PFAS-free textile protection: Drop-in solutions for industrial finishing and consumer DIY care
Technology overview
Nanopool develops and supplies PFAS-free, water-based textile coating formulations based on ultrathin SiO₂ technology. They provide suitable textiles with water-repellent surface properties, help reduce the adhesion of water-based contaminants and facilitate cleaning. The treatments are designed to preserve the textile’s appearance, feel and breathability.
The technology is available as a drop-in solution for suitable existing industrial textile finishing processes and in formulations for consumer DIY application to finished textile products. Nanopool supplies the coating formulations, not the finished textiles.
Industrial and consumer applications
Industrial applications include integration into existing finishing processes at textile manufacturers and industrial finishers. Relevant areas include sportswear, performance apparel, outdoor fabrics, technical textiles and interior textiles.
Consumer DIY applications enable users to apply suitable formulations directly to finished textile products. This creates opportunities for consumer textile-care and protection products for upholstery, carpets, home textiles and suitable clothing and outdoor textiles.
Potential applications include: • Sportswear, performance apparel and outdoor textiles. • Technical and industrial textiles. • Upholstery and furniture fabrics, including sofas and chairs. • Home textiles, including curtains and decorative fabrics. • Carpets, rugs and textile floor coverings. • Automotive interior textiles.
Suitable natural and synthetic fibres can be treated. Formulation, application method and process parameters are selected according to the textile and intended use.
Validation and market readiness
The textile coating technologies are commercially available and already on the market. Selected NP® Fibre Protect formulations hold OEKO-TEX® ECO PASSPORT certification and meet ZDHC MRSL Level 1 requirements. Product-specific PFAS testing documentation is available for relevant formulations.
Performance, durability, material compatibility and preservation of textile properties depend on the formulation, substrate and application conditions and are assessed for the intended use.
Collaboration opportunities
We are seeking textile manufacturers, industrial finishers, sportswear and outdoor brands, furniture and home textile producers, and consumer textile-care companies.
Collaboration can include coating supply, substrate-specific application trials, industrial process integration, co-development of consumer DIY textile-protection products and licensing partnerships.
Our objective is to make PFAS-free textile protection accessible both within industrial production and through application by consumers.

About Nanopool GmbH
Nanopool GmbH is a German nanotechnology research and development company founded in 2002 that specializes in functional surface coatings based on proprietary Liquid Glass (SiO2) technology. The company operates as a technology platform, focusing on the development and manufacturing of ultra-thin, transparent, and environmentally friendly protective layers. These coatings are engineered to provide surfaces with specific properties, such as water and dirt repellency, antimicrobial protection, and durability, while largely maintaining the original appearance, feel, and breathability of materials like glass, metal, plastic, textiles, and paper. Their products are developed through interdisciplinary research and are often patented or patent-pending, with a strong emphasis on sustainability and resource efficiency.
By providing tailored coating systems, Nanopool helps partners across diverse industries—including healthcare, construction, photovoltaics, and sustainable packaging—to enhance product performance, improve hygiene, and reduce maintenance requirements. Their SiOPack initiative, for instance, offers a recyclable, plastic-free barrier coating for paper-based packaging that protects against moisture and grease. The company’s solutions have been recognized with numerous scientific and environmental awards and are designed for integration into industrial production processes, helping customers achieve more durable, hygienic, and sustainable material applications.
