TANATEX Chemicals has introduced a fluorine-free water repellency concept aimed at helping textile mills and finishers replace fluorocarbon-based durable water repellent (DWR) chemistry without sacrificing wash durability or process reliability, as manufacturers worldwide face mounting pressure from PFAS-related regulations.
The Netherlands-based chemicals supplier, a company of Transfar Chemicals, said its Durable Water Repellence concept combines fluorine-free repellent technologies, booster systems and technical application expertise rather than offering single-product substitutes, an approach it says addresses the trial-and-error challenges mills encounter when switching chemistries.
Fluorocarbon-based water repellency is being phased out across the textile industry as PFAS restrictions tighten, but performance expectations from brands and end users have not eased, TANATEX said. Fluorine-free alternatives behave differently across fibre types, fabric constructions, application methods and curing conditions, meaning a formulation that performs well in one production setup can fall short in another.
The concept centres on six BAYGARD-branded products covering different fibre and performance needs. BAYGARD BIO-FFS is a bio-based, non-fluorinated repellent suited to synthetic fabrics. BAYGARD FCF 01 targets synthetic fibres and blends with moderate wash durability and is designed for continuous application. BAYGARD LTR 01 is a bio-based option for cellulosic fibres and blends, usable in both continuous and discontinuous processes.

BAYGARD I-WR is positioned for cellulosic materials requiring strong dry repellency and high wash durability, while BAYGARD N-S is a universal hydro-repellent offering resistance to laundering and dry cleaning. BAYGARD WRS rounds out the range as a universal fluorine-free DWR for all fibre types and blends.
TANATEX said performance depends on more than the repellent chemistry alone, with fibre type, fabric construction and process conditions all influencing outcomes. By pairing the right auxiliaries with products selected for specific fibre and process conditions, the company said mills can achieve more consistent results and reduce the number of production trials needed to reach target specifications.
The company is positioning the concept for textile mills and finishers phasing out fluorocarbon chemistry, brands seeking to stay ahead of PFAS restrictions, and technical teams in performance and technical textile segments including outdoor, workwear, luggage and leisurewear. TANATEX said the approach fits existing production routes, including continuous and discontinuous application, and does not require mills to adopt a fixed bundle of products.
The push comes as the broader fluorine-free coatings segment gains momentum. Green Theme Technologies, developer of the EMPEL clean-chemistry DWR platform, has said fluorine-free alternatives now match PFAS-based coatings on water repellency and wash durability after early-generation formulations struggled with stiffness and reduced performance. Industry analysts covering the space expect fluorine-free technology to become the standard for textile coatings within the next decade as regulatory enforcement and brand sustainability commitments intensify.
TANATEX said its concept is intended to shorten that transition timeline for mills by pairing chemistry selection with technical guidance rather than leaving finishers to identify compatible product combinations independently, reducing development time and lowering compliance risk associated with fluorocarbon chemistry.
TANATEX has published a handout detailing the concept’s performance data and product combinations for mills evaluating fluorine-free transitions.
