PFAS-FREE

The PFAS-FREE project aims to sustainable and high-performance water repellency  in the textile industry. While many alternatives on the market today claim to be PFAS-free, they often fall short in performance or sustainability.  

The PFAS-FREE project aims to go further by delivering solutions that are not only fluorine-free but also safer, more sustainable, and better performing than what is currently available. 

Why PFAS-Free Matters 

PFAS (per- and polyfluoroalkyl substances) have long been used in textiles for their exceptional water and stain resistance. However, they come at a high cost: they are persistent, bioaccumulative, and toxic.

PFAS compounds accumulate in ecosystems and living organisms over time, posing serious health risks, including cancer. 

In Europe alone, an estimated 50,000 to 80,000 tonnes of PFAS are used annually in functional textile applications. Despite growing awareness and regulation, viable alternatives remain limited.  

The PFAS-FREE project addresses this urgent need by developing eco-friendly water repellents that do not compromise on performance. 

A Collaborative Research Effort 

The project brings together leading research institutions: Centexbel, UCLouvain, ULiège, and UGent. Their combined expertise ensures a multidisciplinary approach, merging:

• material science
• sustainable chemistry
• environmental assessment 

Centexbel is focusing on the development of two materials:

• hydrophobic bio-based polyurethanes (PU)
• non-isocyanate polyurethanes (NIPU)

These innovative materials are being applied to common textile substrates such as polyester and cotton to achieve superior water repellency without the use of fluorine.  

These materials are then combined with a structured surface developed by UCLouvain, ensuring an innovative approach to achieve durable, water-repellent  textiles.  

From Molecule to Market: Designing for Safety and Sustainability 

To ensure the materials and processes are effective and aligned with long-term sustainability goals, ULiège and UGent are conducting an inclusive Safe and Sustainable by Design (SSbD) study, including LCA and ecotoxicity analysis. This framework will enable:  

• material selection 
• a choice of processing techniques
• environmental impact assessments  

This approach ensures that the final products meet the highest safety and sustainability standards. 

Enabling the Circular Economy Through Smarter Textiles 

By removing PFAS from textile production and replacing them with bio-based, biodegradable alternatives, PFAS-FREE directly contributes to a more circular economy. The materials under development are designed to have a lower environmental footprint and to support better end-of-life management, such as recycling or safe degradation. 

Creating Value for Businesses and Consumers 

For textile manufacturers and SMEs, PFAS-FREE opens the door to next-generation product lines that meet stricter regulations and growing consumer demand for safer products. These innovations offer a competitive edge in a market where sustainability is fast becoming a key differentiator. 

Whether it's for outdoor gear, technical fabrics, or everyday apparel, the solutions developed by PFAS-FREE promise to deliver water repellence that is both high-performing and future-proof. 

A New Standard for Functional Textiles 

The PFAS-FREE project is more than just a research initiative; it's a call to action for the textile industry to innovate responsibly. By combining cutting-edge science with circular economy principles, the project is setting a new benchmark for what sustainable textile performance can look like. 

For businesses ready to lead in sustainable innovation, PFAS-FREE provides both the tools and the vision to create textiles that respect people, the planet, and the future.
