Patagonia’s Durable Water Repellent (DWR) application progresses from C8 to C6 for outdoor sportswear.
Patagonia—as well as other high-quality outdoor outerwear suppliers—for years relied on a Durable Water Repellent (DWR) of a certain chemistry (described below) to bead up, then disperse, surface moisture from rainwear. It is necessary, even in a waterproof jacket, to prevent surface saturation. ...Read more -
Is the silicone waterproofing agent used in fabric water-repellent finishing a fluorine-free waterproofing agent?
1. Fluorine-based waterproofing agents and fluorine-free waterproofing agents The fluoride contained in the carbon eight and carbon six fabric waterproofing agents currently used on the market is difficult to degrade. Finding alternatives to fluorine-based fabric waterproofing agents has become a...Read more -
Principles and test methods of fluorine-free anti-siphoning
1. What is anti-siphoning? Anti-siphonage can be divided into two types: static and dynamic. This article mainly introduces static anti-siphonage. In shoe material processing or leather anti-siphon finishing, static anti-siphonage refers to a performance that prevents water or liquid from being s...Read more -
Why carbon six waterproofing agent does not contain PFOA.PFOS.APEO?
