For Professional Textile Care, water-repellent finishing is entering a new phase. Technologies that have delivered reliable protection to outdoor garments, functional clothing and technical textiles for many years are increasingly being reassessed as European chemicals regulation evolves. The challenge for textile care professionals is therefore becoming broader than simply replacing one chemistry with another: future impregnation has to combine performance, textile compatibility and process reliability with changing regulatory requirements.

PFAS – per- and polyfluoroalkyl substances – have played an important role in many technical applications because fluorinated chemistries can provide highly effective surface properties. Their exceptional persistence, however, has also made them a growing environmental concern. Some PFAS can remain in the environment for very long periods, which is why the group is frequently associated with the term “forever chemicals”.

European regulation has consequently been moving step by step. Restrictions already apply to individual PFAS and specific PFAS groups. More recently, Regulation (EU) 2024/2462 introduced restrictions concerning PFHxA, its salts and PFHxA-related substances, including certain uses in textiles, leather and footwear. At the same time, the much broader proposal to restrict PFAS under REACH remains a separate European regulatory process.

More Than a One-to-One Replacement

For textile care companies, the practical implications are significant. Moving away from established fluorinated technologies cannot always be treated as a simple one-to-one substitution.

Outdoor clothing, sportswear, membrane garments and other functional textiles can differ considerably in construction, fibre composition and intended use. The required level of water repellency may also vary. It is important to note that this discussion does not focus on personal protective equipment (PPE), for which specific exemptions apply under the current PFHxA restriction. Alternative finishing technologies therefore need to be evaluated in relation to the textile itself, the care process and the performance actually required.This makes application knowledge increasingly important.

A technology suitable for one category of garment or technical textile may not automatically be the best choice for another.

PFAS Is Only Part of the Regulatory Picture

The development also demonstrates why Professional Textile Care companies need to look beyond a single substance group. The EU has, for example, separately introduced a REACH restriction for intentionally added synthetic polymer microparticles. PFAS regulation and the microplastics restriction are different regulatory issues, but together they illustrate a wider trend: textile finishing chemistry is being assessed increasingly closely from an environmental and regulatory perspective.

For laundries and professional textile cleaners, this means that purchasing decisions will increasingly require more than a simple “PFAS-free” label. Claims need to be clearly defined, regulatory developments monitored and finishing technologies matched carefully to their intended applications.

The future of impregnation is therefore not about finding one universal replacement. It is about achieving the right balance between required protection, textile compatibility, process conditions, environmental considerations and regulatory compliance.

For Professional Textile Care, that transition has already begun.
