ITNs remain one of the most important tools for preventing malaria. However, their effectiveness depends not only on insecticidal performance, but also on whether the net remains physically intact and functional over time. In many settings, nets are expected to provide protection across a three-year distribution cycle, yet real-world durability can vary significantly depending on product construction, use conditions, user habits and local environmental factors.

NIRI researchers have collaborated on this breakthrough project with Bill and Melinda Gates Foundation, WHO and Innovative Vector Control Consortium (IVCC) to address the challenge of developing laboratory-based methods for assessing the resistance of mosquito-net structures to real-world modes of damage. This work has involved developing the resistance-to-damage score, or RD score, a single metric designed to reflect key physical performance attributes including bursting strength, snag strength and resistance to hole enlargement.

The new WHO technical consultation report discusses the evolution of this work into the weighted resistance-to-damage score, or wRD score, and considers how it could help link laboratory performance to operational life in the field. The report notes that wRD was positively associated with median net lifespan and that improved durability scoring could support more value-based procurement decisions.

This is a significant moment for applied textile science. By translating the mechanisms of field damage into measurable laboratory tests, NIRI’s work is now helping to create a stronger evidence base for how future ITNs are designed, assessed and selected.

Professor Stephen Russell, Technical Director of NIRI Group, said:

“Physical durability is a critical factor governing the effectiveness of ITNs. NIRI’s work focused on understanding how and why nets fail in use, then developing practical textile tests along with a new metric to inform new product development and procurement decisions. It is encouraging to see the importance of ITN durability measurement being discussed at global level.”

The WHO report also highlights the broader opportunity for durability metrics to support value-based procurement, where decisions consider not only the purchase price of a net, but also its likely period of effective protection. This approach could help to incentivise innovation, improve the allocation of resources and support malaria programmes in maintaining protection between distribution campaigns.

NIRI’s contribution to this field is set out in a series of peer-reviewed Journal papers:

1. Development of a single resistance to damage metric for mosquito nets related to physical integrity in the field. Read more here.
2. Physical durability: are bed nets getting any stronger? Read more here.
3. The causes of holes and loss of physical integrity in long-lasting insecticidal nets. Read more here.
4. Textile testing to assess the resistance to damage of long-lasting insecticidal nets for malaria control and prevention. Read more here.
5. Correlation of textile ‘resistance to damage’ scores with actual physical survival of long-lasting insecticidal nets in the field. Read more here.

As the sector seeks to refine and validate durability-testing protocols, NIRI will continue to support the translation of textile science into practical tools that improve product performance, procurement decisions and public-health outcomes.

Matthew Tipper, NIRI’s CEO, says “to see NIRI’s pioneering work help improve mosquito net performance and contribute to saving lives is testament to collaborative innovation.”

The NIRI team returned from INDEX™26 energised by four days of valuable conversations, new connections and a renewed sense of momentum across the global nonwovens industry.

Held at Palexpo in Geneva from 19–22 May, INDEX™26 once again brought together the full nonwovens supply chain, from raw materials and machinery to converters, brands, researchers and end users. For NIRI, the event provided an important opportunity to meet with partners, industry peers and prospective clients from across the world, and to explore how innovation can help the sector respond to both immediate challenges and long-term opportunities.

Throughout the exhibition, one message came through clearly: the future performance of the nonwovens industry will depend on its ability to innovate. In a market shaped by economic uncertainty, regulatory pressure, sustainability expectations and changing customer needs, innovation is no longer simply about developing new products. It is about improving performance across the whole value chain.

That means designing materials that do more with less. It means developing lighter, more efficient and more sustainable nonwoven structures. It means rethinking product construction, optimising manufacturing processes, reducing carbon impact and enabling greater circularity. Above all, it means bringing technical expertise and commercial ambition together to create solutions that are practical, scalable and ready for the market.

INDEX™26 demonstrated the strength and resilience of the sector. The exhibition halls reflected an industry that is continuing to invest, adapt and collaborate, even while navigating pressure on supply chains, costs and global markets.

For NIRI, this spirit of collaboration was one of the most encouraging aspects of the event. Innovation is rarely the result of a single breakthrough in isolation. It is built through partnerships that combine market insight, technical capability, process knowledge and a clear understanding of end-use requirements.

A key theme at INDEX™26 was the integration of technical performance and environmental responsibility. Across the show, sustainability was not presented as a separate objective, but as a core part of product and process performance. The exhibition highlighted how the industry is moving towards solutions that deliver both functionality and reduced environmental impact.

This is a direction NIRI strongly supports. Innovation has a vital role to play in helping the nonwovens sector improve sustainability without compromising on performance. Whether the challenge is reducing material consumption, improving filtration efficiency, developing bio-based or biodegradable options, replacing problematic chemistries, improving durability, or scaling a new product concept, the most effective solutions come from a deep understanding of both materials and manufacturing.

At INDEX our CEO, Matthew Tipper, discussed how the move away from plastic-containing wipes is reshaping the wipes value chain, from fibre and substrate selection through to product performance, packaging, claims and commercialisation. The talk highlighted the following key takeaways:

1. Regulation is shifting sustainability from a voluntary improvement to a mandatory product redesign challenge.
2. Innovation is moving upstream into fibre, substrate and nonwoven architecture development.
3. Plastic-free wipes must still meet consumer expectations, retailer cost pressures and scale-up requirements.
4. Competitive advantage will come from integrated solutions: plastic-free fibres, engineered nonwovens, compatible chemistry, robust packaging, traceability and credible claims.

As a result, future success will depend on designing complete wipe systems that balance compliance, consumer experience, technical performance and commercial viability.

INDEX™26 also reinforced the need for agility. As regulations tighten and customer expectations rise, companies must be able to adapt quickly. Innovation helps businesses stay ahead of change, turning compliance challenges into opportunities to create differentiated, market-ready products.

The nonwovens industry will increasingly be judged not only on output, cost and speed, but also on resource efficiency, adaptability and environmental impact. Companies that invest in smarter material selection and process optimisation will be better placed to develop products that are more efficient, more sustainable and aligned with future market needs.

By supporting the journey from concept and feasibility through to prototyping, testing and scale-up, NIRI helps organisations turn ideas into high-performing material solutions.

Our time at INDEX™26 reinforced our belief that the nonwovens industry has an exciting future. The sector is already central to essential applications across hygiene, healthcare, filtration, packaging, personal protection and more. As expectations continue to rise, nonwovens have the potential to deliver even greater value through improved performance, reduced environmental impact and new functionality.

We would like to thank everyone who visited the NIRI team during the exhibition. The conversations we had throughout the week reflected the ambition, creativity and shared commitment that continue to drive this industry forward.

INDEX™26 showed that, even in uncertain times, the nonwovens sector remains focused on progress. Through innovation and collaboration, the industry can build resilience, boost performance and create the next generation of materials needed for a more sustainable future.

We look forward to continuing the conversations beyond the show.

Improving margin in nonwoven production is often approached through pricing or cost-cutting. But in practice, the biggest gains come from something more fundamental; delivering the same customer outcome with less waste, less variability, and less complexity without increasing risk.

In this article, we outline a practical 5-step roadmap to improve margin.

Step 1: Increase Saleable Output 

Profit is lost whenever you make material that cannot be shipped.

Focus on:

• Reject reduction: identify the three biggest defect types and remove their causes (web non-uniformity, bonding instability, winding damage, contamination).
• Faster grade changes: improve start-up efficiencies with standard machine settings and fast checks.
• Less unplanned stoppage: treat critical components (dies/nozzles/rolls/filters) as measurement tools, when condition drifts, defects rise.

Step 2: Reduce Material Usage 

Many products carry “extra grams” because specifications are not tied tightly to real use conditions. By defining measurable outcomes and designing smarter structures, weight can be reduced without sacrificing function.

Focus on:

• Clearly defining the customer outcomes in measurable tests: for example, filtration efficiency and pressure drop, fluid uptake and rewet, abrasion resistance. 
• Reducing mass with structure, not hope: use layered designs so more expensive fibres or chemistry sit only where they are needed to work.
• Mapping the safe operating window: run controlled trials so you know where performance drops sharply and set limits before scale-up.

Step 3: Rebalance Raw Materials 

Raw materials cost money twice; once when you buy them, and again when their variability creates scrap, claims, or over-processing.

Focus on:

• Blend optimisation: adjust fibre types and ratios to hit performance at minimum cost.
• Remove “nice-to-have” chemicals: keep only what measurably improves processing, performance, or durability.
• Control variability at the gate: set acceptance limits for incoming material properties so the process stays stable.

These efficiencies directly reduce operational risk and shrink the environmental footprint of processing.

Step 4: Reduce Energy and Utilities 

Energy is often used to compensate for instability. Improve process control to reduce the need for excess energy. 

Focus on:

• Drying and heating: recover heat, control exhaust humidity, balance airflow, and avoid overheating. 
• Water and filtration systems: keep filtration and nozzle condition high so you don’t need higher pressure to get the same effect.
• Compressed air: fix leaks and lower pressure where possible, small changes have large cost effects.

Step 5: Simplify the Product Range 

Every additional product variant increases complexity, testing burden, inventory, and opportunities for error.

Focus on:

• Building platform families: create a small number of base materials, then add features only where customers pay for them.
• Eliminating low-value variants: keep differences only when they deliver a measurable customer outcome.
• Pricing for performance: where function is proven, sell the outcome delivered, not the material used.

The common thread across all five steps can be summarised as follows: optimise for customer outcome and remove everything else that doesn’t contribute.

However, this isn’t about trying to tackle everything at once. The most effective approach is to start with yield, capture the quick wins, and then improve step-by-step from there.

When approaching margin improvement, the key question is: where are you seeing the biggest margin losses today, materials, waste, or complexity?

In our previous article, we highlighted how lightweighting, monolayer constructions, and mono-component solutions are gaining traction as manufacturers pursue performance with less material use and improved recyclability. Now, we want to address a challenge, and opportunity, which sits at the heart of sustainable manufacturing: energy and resource efficiency.

For nonwoven and textile manufacturers, energy is a critical input that shapes competitiveness, environmental impact, and long-term resilience. The industry remains energy intensive throughout its process chain, from fibre preparation to bonding and finishing. Improving energy efficiency is no longer optional to future-proof operations in a climate-constrained world. 

1. Resource Efficiency: More Than Just Cost Cutting

Lightweighting and mono-component materials are not just sustainability buzzwords; they are strategic levers for resource efficiency. By reducing material consumption while maintaining or enhancing performance, manufacturers cut embodied energy upstream and lower the operational energy tied to processing heavier, more complex constructions. 

Why it matters:

• Fewer material types mean fewer process steps, fewer energy-intensive bonds, and fewer chemical inputs.
• Lighter materials often require less thermal and mechanical energy to process.
• Mono-component systems simplify recycling and reduce energy costs during end-of-life handling.

2. Low-Energy Production & Bonding Technologies

Manufacturers are increasingly adopting bonding technologies that reduce both energy and water use:

• Thermal bonding with optimised heat profiles and active cooling control.
• Airlaid and hydroentanglement processes that reduce reliance on high-energy drying stages. 

These approaches do not just save energy, they reduce water usage and emissions too, driving multi-dimensional efficiency.

3. Water & Dyeing: A Big Piece of the Efficiency Puzzle

Wet processing remains one of the most energy and water-intensive phases of textile production. But strategic interventions can make a big difference:

• Sustainable dyeing techniques such as digital printing and low-impact dyes reduce both water and energy per batch. 
• Heat recovery systems reuse energy from process exhaust streams to pre-heat water or air, cutting net energy demand.
• Process automation and real-time monitoring help eliminate over-processing, another unseen drain on resources.

These efficiencies directly reduce operational risk and shrink the environmental footprint of processing.

4. Supply Chain & Process Optimisation: Immediate and Long-Term Gains

Strategic analysis of process capability and manufacturing workflows can identify bottlenecks and energy hotspots. By rethinking layout, sequence, and resource scheduling, companies can significantly reduce peak loads and wasteful energy spikes.

Examples include:

• Energy audits to benchmark performance and pinpoint opportunities.
• Smart controls and sensors to shut down idle equipment and optimise heating/cooling cycles. 
• Data-driven manufacturing optimisation using emerging AI tools to balance efficiency and output.

This is where the dual benefits of immediate savings and long-term resilience converge, smarter processes make operations leaner and more adaptive.

5. Renewables, Low-Carbon Energy Integration & Science-Based Targets – Why 2026 is a Pivotal Year for Action

Energy efficiency improvements inside the factory are critical but they are only part of the decarbonisation equation. Increasingly, manufacturers are aligning operational strategy with structured frameworks such as the Science Based Targets initiative (SBTi).

SBTi provides companies with a clear methodology to set greenhouse gas reduction targets aligned with climate science and the goals of the Paris Agreement. For textile and nonwoven manufacturers, this typically means:

• Reducing Scope 1 emissions (direct emissions from owned or controlled sources)
• Cutting Scope 2 emissions (indirect emissions from purchased electricity, heating, cooling)
• Addressing Scope 3 emissions (all other indirect emissions across the value chain), which is often the largest proportion of emissions, including raw materials, logistics, and end-of-life impacts

While more than 11,000 companies and financial institutions have already set science-based targets or committed to doing so, SBTi is currently developing an updated Corporate Net Zero Standard, V2.  Incorporating new technical standards, this will include incentivisation for companies taking early, voluntary action to remove emissions.  From 1^st January 2028, all companies will need to use this new Net Zero Standard – those that act now will gain competitive advantage.

ISO: The International Organisation for Standardisation is currently reviewing the first internationally recognised Net Zero Standard, ISO 14060.  This will set out the requirements for how organisations can demonstrate targets and delivery on these, showing credible and verifiable progress, aligned with the Paris Agreement, and guarding against greenwashing.  It will ensure a consistent, internationally agreed approach to carbon accounting.  It is anticipated that this Standard will be published mid to late 2026.  Companies acting now to align with ISO 14060 will be better prepared to meet disclosure requirements, particularly when working across multiple territories and jurisdictions.

The implications are significant. Energy strategy is no longer about efficiency, it becomes part of a company’s formal decarbonisation roadmap which is increasingly scrutinised by customers, investors, and regulators.

Practical steps include:

• Transitioning to renewable electricity through on-site solar, wind, or power purchase agreements (PPAs)
• Electrifying thermal processes where feasible, supported by industrial heat pumps and electric boilers
• Implementing heat recovery and energy cascading across production stages
• Collaborating with suppliers to reduce embodied carbon in raw materials

For many organisations, Scope 3 reduction, particularly in polymer and fibre sourcing, is now the defining challenge. This is where material optimisation, lightweighting, and mono-component design become powerful levers, reducing both raw material intensity and upstream emissions.

Conclusion: Efficiency as a Competitive Advantage

Nonwoven and textile manufacturing operate in a global environment of rising energy prices, tightening climate regulation, and increasingly conscious customers. With material optimisation, low-energy technologies, water reduction, and supply chain optimisation, manufacturers can turn energy challenges into strategic advantage.

Meeting sustainability goals doesn’t mean accepting lower performance or higher costs. Rather, it means re-thinking how we use energy and materials and in doing so, unlocking value across the entire value chain.

At NIRI, we see these challenges every day across nonwovens and technical textiles. Energy efficiency, material optimisation, and supply chain resilience are rarely solved by a single intervention, they sit at the intersection of product design, process capability, and manufacturing reality.

Our work supports manufacturers across:

• Product development, including lightweighting strategies, mono-component and monolayer constructions, and performance-led material selection
• Manufacturing and process optimisation, helping identify energy hotspots, reduce waste, and improve process capability
• Supply chain and sourcing support, ensuring materials and processes are not only technically sound, but scalable, resilient, and commercially viable

By taking a holistic view from concept through to industrialisation we help clients reduce energy and resource intensity while protecting performance, margins, and long-term competitiveness.

2025 was a milestone year for NIRI as we proudly marked 20 years of supporting commercial innovation across nonwovens, textiles, and advanced materials. As a group it was important that we took a moment to reflect on our history, the partnerships, expertise, and problem-solving that have shaped our journey. Now, as we turn our focus to 2026, the pace of change shows no sign of slowing.

As we enter 2026, the nonwovens and textiles industries face another defining year. Sustainability targets are tightening, regulatory obligations are accelerating, and cost pressures remain a constant challenge. Yet with these pressures come significant opportunities – for innovation, efficiency, and competitive diversification.

At NIRI, we see 2026 as a year where technical excellence, regulatory readiness, and smart supply-chain decisions will be critical to success and we are ready to support customers through these challenges.

Cost and Energy Efficiency: Doing More with Less

Cost saving remains a priority across manufacturing sectors, but in 2026 it is increasingly linked to resource efficiency and energy reduction rather than simple cost-cutting. Lightweighting, monolayer constructions, and mono-component solutions are gaining momentum as manufacturers look to reduce raw material use while maintaining performance.

Alongside material optimisation, low-energy production and bonding technologies, reduced water usage, and waste minimisation are becoming essential tools for maintaining margins. Supply chain optimisation, through process capability analysis, manufacturing optimisation, and improved material selection, can deliver both immediate savings and long-term resilience 

NIRI’s Supply Chain & Manufacturing Support services are designed to help companies identify inefficiencies, optimise processes, and support measurable progress toward cost and energy reduction goals.

Net Zero and Science-Based Targets

Net zero commitments and Science Based Targets initiative (SBTi) alignment are now moving from ambition to execution. In 2026, companies will be expected to demonstrate credible plans backed by data—covering Scope 1, 2, and increasingly Scope 3 emissions.

Process optimisation, energy-efficient manufacturing routes, and material substitution all play a role. Independent technical assessment and life-cycle thinking can help businesses make decisions that are both environmentally and commercially sound.

Materials Innovation: Biobased and Recycled Solutions

The adoption of biobased materials and the rapid development of fibre and textile recycling technologies, including mechanical, thermal, enzymatic and chemical, continue to reshape product design. While these technologies offer clear sustainability benefits, they also introduce technical, performance, funding/ investment, and regulatory challenges.

Balancing recyclability, functionality, and compliance requires robust testing, validation, and expert guidance. NIRI supports companies across the innovation lifecycle, from early-stage material evaluation through to scale-up and market readiness.

Regulatory Readiness: From PFAS to Textile Waste

Regulatory change will be one of the most significant drivers of activity in 2026.

One major development is the EU restriction of PFHxA and related substances under Regulation (EU) 2024/2462. From 10 October 2026, products placed on the market must not exceed:

• 25 ppb for the sum of PFHxA and its salts, or
• 1000 ppb for the sum of PFHxA-related substances

Ban on Plastic Containing Wipes

In the UK, the upcoming ban on plastic-containing wet wipes adds further urgency. Scotland is expected to implement the ban around April 2026, Wales from December 2026, and the UK-wide ban comes into force in May 2027—impacting baby wipes, cosmetic wipes, and household cleaning wipes sold both in-store and online 

Navigating this evolving regulatory landscape requires not only awareness, but proactive planning, organisation, technical validation, and clear documentation.

Industry Events: INDEX26 and Techtextil

Key industry events in 2026 will play a vital role in shaping the year ahead. For example, INDEX26 will showcase the latest innovations, sustainability solutions, and regulatory developments in nonwovens, while Techtextil will be a focal point for technical textiles and advanced material applications.

These events offer valuable opportunities to explore emerging technologies, share best practice, develop collaboration and partnerships and understand how the industry is responding to global challenges.

2003: Chris Fowler and Professor Stephen Russell meet – and immediately saw the potential for collaboration
Steve was then – and still is today – one of the leading minds in nonwovens and technical textile engineering.  At this time, he led a nonwovens research group at the University of Leeds.  Chris, with a background in running innovative medical technology companies, was looking for an investment opportunity – a business where he could make a major contribution, and ideally one based in Yorkshire.

2004: a spin-out is negotiated
The University of Leeds, where Steve’s research group was based, were looking to spin-out and commercialise cutting-edge innovation and product development capabilities from this world-class textile expertise, with the help of a commercially minded investor.  Chris and Steve’s skillsets aligned in a compelling case for the birth of NIRI.

2005: NIRI Limited is formed
The company is established, with Chris as Managing Director and Steve as Technical Director, combining the commercial acumen with the technical rigour that remain very much the core values of NIRI to this day.

2007 – 2014: expansion, facilities, and people – and a £1 million turnover
From the outset, NIRI knew that world-class consultancy is only possible with world-class talent – the driven individuals that make up a team passionate about technical textile development for real-world, commercial product development.  And it is testament to this approach that the company’s first recruit, Dr. Matthew Tipper, is now NIRI’s CEO.

To provide the best possible service to clients, NIRI started out with an investment-led philosophy, with a clear focus on the facilities and equipment needed to ensure both the opportunity to experiment with technical textile development  – the cutting-edge commercial research that has always underpinned NIRI’s offering – and to facilitate the speed to market necessary for optimum return on investment for clients.

NIRI achieved a first licence deal for a new textile product within four years of spin-out.  And 2013 marked a £1 million-plus turnover from commercial consultancy.

2015 – 2017: success leads to funding – and further expansion
Growth in NIRI technologies was supported by several grant awards and significant investor funding.  10 years on from the company’s formation, NIRI’s commercial success led to expansion with new premises – now off the University campus and into an 11,000 ft² facility.  And this investment and expansion incorporated a range of new equipment to help develop, test and manufacture better-performing products for NIRI’s expanding client base.

A laboratory-scale electrospinner meant NIRI could respond to the growing use of nanofibres for clients across a wide range of sectors, for small-scale investigation prior to scaling up to larger sample sizes.  A flatbed hydroentanglement pilot line was installed in the new premises, with the flexibility to allow for fabric structure and properties to be tailored to specified requirements.  A new Scanning Electron Microscope (SEM) provided an additional tool for understanding how manufacturing conditions affect the microstructure of nonwovens, and integrated image analysis software meant that NIRI could quantify fibre dimensions, pore size and other structural features more effectively. And investment in a new liquid extrusion capillary flow porometer helped NIRI’s clients quantify the through-pore diameters present in a nonwoven structure. 

Recognising and anticipating the growth in the hygiene sector, NIRI invested in bespoke testing equipment, including liquid strike through time and re-wet. Additional testing equipment included a fluff pulp specific volume and absorption tester, to balance wet strength and user comfort alongside biodegradability and dispersibility, all aimed at helping clients enhance existing products, with cost-reduction and quality improvement, and to help identify and evaluate new markets.

2018 – 2022: company changes, awards, investment and independence
Having moved from university premises in the previous year, one of NIRI’s Technologies was sold in 2018, and NIRI continued global expansion and consultancy, to turn ideas into products and sales more rapidly. The company’s collaborative approach to innovation saw a win with The Engineer C2I (Collaborate to Innovate) Award for the Sanguis universal plasma technology, in partnership with NHS Blood and Transplant and Macopharma.  And the Surfaceskins antibacterial door-push and -pull product received the 2019 Innovation Award at the Research, Innovation & Science for Engineered Fabrics (RISE®) Conference.

Major investments over these four years included:

• A new V-Lap machine to help clients develop applications for 3D vertically lapped nonwoven fabrics.
• A new airlaid system capable of prototyping pilot-scale samples containing high proportions of wood pulp and other very short fibres, to support clients in the hygiene and medical sectors. 
• Upgrade to the latest meltblown technology – an investment particularly relevant for clients’ R&D, pilot projects, sampling and prototyping, and proof of concept testing, for enhanced functionality and the rapid development of innovative and commercially-viable products.
• Bespoke-engineered spray bonding capability, to enable products to meet current and future regulatory demands, and to help investigate and develop better-performing products with improved functionality.

Alongside this investment, NIRI expanded their team and expertise, with more than 20 additional staff joining the company in 2021, alone – including principal scientists, senior innovation engineers, and technicians.  With project delivery doubling, NIRI achieved full independence in 2022, following a buy-out from the University. NIRI’s consultancy continued to have impact during this period, and work on one dual-AI net technology has been proven to reduce malaria cases and has recently been calculated as saving more than 24,000 lives.

2023 – a landmark year with the opening of Innovation House
Following 2022’s year of growth, NIRI relocated to new headquarters in Leeds with a £1.2 million investment, more than doubling the size of the facilities, with seven new laboratories and significantly increased R&D capabilities designed in close collaboration with NIRI’s textile engineers and material scientists.

¹

As part of a three-year strategy for growth, much of the new equipment at Innovation House is bespoke to NIRI, with new labs designed to foster the expansion of NIRI’s functional chemistry, formulation, and polymer engineering capability. This was coupled with the expansion of NIRI’s US presence, and further investment in NIRI’s 40-strong team.

Unveiling a plaque to commemorate the opening of Innovation House, the Rt. Hon. Hilary Ben, MP for Leeds Central, highlighted the pivotal role NIRI play in the development of sustainable, commercially driven nonwoven innovation,

“You are helping to design the future… Creating products that are genuinely biodegradable, will not add to the problems of the planet, that will help us to solve climate change – you couldn’t be doing a more important job.”

2023 onwards – and looking to the future of textile innovation
NIRI’s investment continues apace: with ongoing investment into biopolymer processing and development; investment in R&D focused on high performance PFAS replacement, and further investment this year in polymerisation facilities.

2025 sees the launch of a new initiative, an innovation hub dedicated to supporting scientific companies grow their ideas into commercial realities.  The Technology & Innovation Hub enables companies to co-locate alongside NIRI’s state-of-the-art facilities – with access to fully-equipped laboratories, private meeting rooms, and office suites – with support services and access to NIRI’s commercialisation expertise through bespoke support packages designed to help start-ups and scale-ups accelerate their innovations into commercially-viable technologies.

The company remains committed to its original commercially driven ethos and, in the current economic climate, helping clients reduce costs and improve efficiency is at the heart of development and innovation.

Chris Fowler reflects on NIRI’s growth and ambitions over the last twenty years, “Our evolution has been a great learning experience and having successfully innovated many novel products across many sectors I am proud of the positive impact the NIRI team has made for our clients, end users and the planet.

I feel our mission to develop cost effective, novel products, which deliver high performance and help protect the planet is even more relevant today than when we started out over 20 years ago.”

Steve Russell adds, “It’s been exciting to be part of NIRI’s 20-year evolution, from small University-spinout to an internationally recognised commercial innovation Company. It’s been a pleasure to work with so many different companies over the years, to deliver meaningful product improvements, and to witness the real-world impact, first hand”.

And Matt Tipper, from the perspective of NIRI’s first recruit to his current position as the company’s CEO, considers NIRI’s future, “After 20 years NIRI continues to build on the founding vision of combining scientific excellence with industry knowledge to help the polymer, textile and nonwoven industry develop new products, solve industrial problems and generate new business.

“Looking to the future, the industry faces a radical change with new regulations, sustainability requirements, cost challenges, social responsibilities and the transition to a circular economy. NIRI is at the forefront of these material challenges and continues to help our clients meet existing and emerging business needs.”

PFAS Legislation is Coming: How Manufacturers Can Innovate and Thrive

As industries strive to become more sustainable, manufacturers face mounting pressure to address a critical challenge: replacing per- and polyfluoroalkyl substances (PFAS).

PFAS are employed for their durability and repellence, making them essential across many protective textile industries, including medical and healthcare, first responder garments, defence and CBRN protection. However, pressure to replace PFAS is growing because these substances are generally known to be toxic, persist in the environment and cause widespread contamination. In addition, research has revealed alarming health risks, including elevated cholesterol levels, pregnancy-induced hypertension, reduced vaccine efficacy, and links to kidney and testicular cancers.

But, PFAS represent a very large chemical family of substances, and they are not all equal in terms of persistence, bioaccumulation and toxicity. Their environmental and health risks are governed by the molecular chain length, functional groups and stability. 

Nonetheless, significant legislative developments are now driving the urgency to replace PFAS, as a result of emerging research. Because of the large number of PFAS compounds, restrictions are focussing on targeted PFAS groups, as opposed to isolated compounds. The Environmental Protection Agency (EPA) and the European Union’s REACH regulations are set to impose severe restrictions on PFAS usage. Amendments to the Stockholm Convention have expanded the list of restricted PFAS, with subsequent effects across international markets. 

Derogations for PFAS usage are likely to be limited and temporary, so businesses across nonwoven and technical textile industries must act now to remain compliant or risk severe penalties and product restrictions. As regulatory pressures increase, protective industries are being called to innovate and address growing consumer demand for safer, more sustainable products. 

Understanding the chemical nature of PFAS and regulatory focus is also vital to the development of new products and applications. Partnering with external expertise can help to navigate these challenges with greater confidence. 

Companies that fail to adapt to such upcoming restrictions may find themselves quickly outpaced by competitors who embrace innovation. The call to replace PFAS is not just a requirement, it’s an urgent mandate that will shape the future of protective apparel and equipment. 

Now is the time for businesses to invest in research and developmentdemonstrate their commitment environmental strategies and position themselves as leaders in sustainability and innovation.

PFAS Alternatives: How the Nonwoven Industry Can Respond

The search for direct PFAS replacements has been ongoing for years and is particularly challenging. PFAS have traditionally delivered exceptional alcohol and fluid resistance due to their unique molecular structure. However, PFAS alternatives often struggle to deliver the same level of performance, as they lack the low surface energy given by carbon-fluoride bonds, which is key to robust liquid chemical resistance – a critical requirement for protective textiles.

Repellence to liquid chemicals is crucial to maintain effective protection against pathogen-laden fluids and chemical exposure in extremely hazardous settings. 

Therefore, this challenge demands innovative approaches. The nonwovens and technical textiles industries need a multifaceted strategy to address PFAS replacement, including:

1. Address Over-Specification: Many products are designed to meet performance standards that exceed actual requirements, leading to the overuse of PFAS. Reviewing these specifications can help decrease reliance on these chemicals.
2. Develop Different PFAS Replacement Strategies: No single solution currently exists for replacing PFAS. However, innovative fabric design, intelligent material selection, and surface functionalisation offer promising pathways forward. At NIRI, we have applied these strategies to develop next-generation PFAS-free products, using a combination of lightweight and breathable high-surface area nonwoven structures with durable woven layer. 
3. Ideate Alternative Coatings and Surface Treatments for Oil, Water and Stain Repellency: utilising expertise in polymerisation and coating technologies, NIRI is developing a PFAS-free polymer, in addition to design and replacement strategies. Polymer properties can be engineered and coatings can be produced without the use of harsh solvents.

Economic headwinds in traditional textile and related markets are being faced by many businesses. To combat this, uncertainty can be turned into opportunity through targeted product innovation and diversification into new application areas. The medical sector can be reasonably resilient during economic downturns, providing attractive opportunities for technical innovators with an awareness of the needs of patients and healthcare providers, the regulatory landscape and the performance limitations of existing products. 

Current Challenges for Manufacturers

Globally, textile and related businesses are contending with inflationary pressures, geopolitical tensions, and shifting consumer behaviour. The uncertainty in some supply chains, coupled with rising material and energy costs, has disrupted traditional business models. Tightening environmental regulation is a further challenge in some markets, affecting the ways products need to be designed, manufactured and quantitatively measured. At the same time, the medical sector is providing pockets of resilience with numerous healthcare products and medical devices now relying on the properties of fibres and engineered textile materials to perform.

Opportunities in the Medical Market

Despite continued economic uncertainty, the medical sector stands out as a robust and largely recession-proof market. Products incorporating textile materials for supporting healthcare and hygiene as well as non-implantable, implantable and extracorporeal medical devices are enabling patient outcomes and reduced morbidity to be achieved in a variety of healthcare settings, whilst delivering attractive margins and costs-in-use. Preventative treatments, diagnostics, remote patient monitoring, wearable technology and products for personalised healthcare are just some of the areas where textile materials are finding new applications to improve patient outcomes, both in medical and community settings. Changes in regulation also open new avenues for innovating, creating new products to deal with performance deficits in currently available products. Although not previously a major driver of innovation in this sector, sustainability concerns and the reliance on single-use plastics for hygiene and infection control has become an area of development.  

Diversifying into the medical sector comes with a unique set of challenges and they vary depending on the country involved, and the specific way in which its healthcare system operates. Product classifications, costs, margins and regulatory compliance are naturally of major importance, but so too is understanding the needs of healthcare professionals and patients, if new products are to provide real-world benefits. When faced with this opportunity, collaboration with external innovation specialists can be valuable, improving targeting, de-risking in-house R&D and accelerating progress towards the creation of competitive products.  Access to the necessary prototyping facilities, testing and structure-property modelling can significantly reduce the timescale between concept and scale-up, reducing commercial risk.

Biomaterials in the Medical Sector

With an evolving healthcare sector, ageing population and growing incidence of chronic conditions there are opportunities to process biomaterials into advanced fibres and fabrics, including nonwovens and coated substrates for use in medical products. Biomaterials, many with multifunctional properties, play a crucial role in providing diagnostic or therapeutic capabilities in contact with biological tissues and organs, with the ultimate aim of improving patient outcomes.

Advanced drug delivery, scaffolds for tissue regeneration, wound care, stents and other implantable devices are among various fibre and fabric based applications. Modified biomaterial formulations, as well as processing methods, are now being explored to manufacture new medical product formats, suitable for a variety of clinical needs. 

The Role of Biomaterials in Fibrous Medical Products 

Certain biomaterials have well established compatibility with existing fibre spinning and textile processing methods, while others are incorporated within mixed polymer formations as components for fibres, or coatings. Certain inorganic compounds can be converted into fibres and fabrics directly, or incorporated within fibres as dispersed nanoparticles.

More commonly, natural biopolymers and synthetic polymers are used as materials for making fibres and filaments (alone, or as additives in commixed polymer formulations), fabrics and porous coatings, as follows: 

• Polysaccharides: e.g., alginates, cellulose including carboxymethyl cellulose (CMC), regenerated cellulose, chitosan, pectin, hyaluronan and dextrin. 
• Polypeptides: e.g., collagen, gelatin, fibrin and various forms of silk. 
• Synthetic polymers: e.g., aliphatic polyesters and copolyesters (including PLA, PGA, PLGA, PCL, PHAs and PHBs), polyanhydrides, polyolefins (including PE, HDPE and UHMWPE, PP), PVOH, polyamides, polycarbonates and polyurethanes. 

Each material formulation is selected based on physical properties, economics, regulatory requirements and compatibility with the appropriate fibre or textile manufacturing platform with specific medical needs depending on the application. 

Challenges and Opportunities in Developing Biomaterials using Textile Processes

Despite the promise of new biomaterials, significant hurdles can be encountered in their development for clinical use. Biomaterials can be challenging to process and manufacture into fibres and fabrics at different scales, often requiring specialist techniques, process modifications and expertise. This can increase development costs and time to market. Meeting regulatory requirements also demands careful planning, good manufacturing practice and validation. Limited infrastructure can be a significant challenge, as many organisations lack the facilities to conduct efficient end-to-end biomaterial development.  

Biocompatibility can be investigated in laboratory settings, but the safety and performance for extended periods of time must also be addressed. Careful consideration and materials selection must be employed.

Materials such as alginate and collagen are sensitive to processing conditions such as temperature, pH, and ionic strength, and over-processing can denature proteins, or alter the molecular structure, affecting material functionality and performance.  

Controlling moisture levels of highly hydrophilic biomaterials during processing is also challenging, but critical to maintaining their structural integrity and performance in the final application.  

Many biopolymers used in medical applications also lack inherent mechanical strength, requiring reinforcement through blending or cross-linking to achieve a balance between flexibility and durability.

Beyond electrospinning to produce nanofibrous webs from polymer solutions or melts, (i.e. products in the form of ‘mats’ and ‘meshes’ and sometimes yarns), developers frequently overlook other highly versatile fibre spinning and fabric forming methods that have the capacity to produce better performing products. This includes wet, dry, dry-wet and gel spinning of biomaterials into continuous filaments, or staple fibres and melt spinning (for thermoplastic polymers). A large variety of fabric forming techniques can then follow, depending on the final products’ required structure-property relationships, and high reproducibility and speed of production are possible. Drylaid, wetlaid and spunlaid nonwovens, followed by appropriate web bonding can enable three-dimensional, porous fabrics to be made very cost effectively from biomaterials than can be challenging to make using other processes.  

NIRI can help to address these challenges by providing access to a comprehensive suite of services, including material innovation, pilot-scale fibre and fabric manufacturing, and performance validation, all under one roof. 

Innovations in Material Processing

In addition to fibre and fabric manufacturing, textile substrates and the materials from which they are made can also be modified. Functionalisation is a key area of innovation. By modifying biomaterials at the molecular level, as well as at the fibre and fabric levels, it is possible to enhance physical properties and therefore performance, tailoring materials to meet precise clinical needs.
