The first generation, shoes, clothing, tents, and sleeping bags were first designed to achieve waterproof and windproof. They only covered the fabric with waterproof glue to achieve waterproofing. The products made by this material and process can withstand certain water pressure, but definitely not. It will be breathable and waterproof and breathable.
The second generation, PU film, this is a kind of material with good water pressure resistance. The product fabric can be combined with it to achieve better waterproof stability. Its high-end products may have some moisture permeability, but the effect is very good. ideal. Such as: the market has KING-TEX, JCT and so on.
The third generation and TPU film have been developed on the basis of PU film. Compared with PU film, it has improved in air permeability, moisture permeability and water pressure resistance. It is a waterproof and breathable film that replaces PU film. There are TING-TEX and KING in China. -TEX, JCT, etc.
The fourth generation, EPTFE (polytetrafluoroethylene) is the latest generation of waterproof and breathable materials. The world's first-class factories use this material, and combined with their own research and development compound processing technology to develop different brands of EPTFE composite fabrics. Waterproof and breathable are the best in today. The main performances in the international market are: GORE-TEX (developed by Gore, USA, and open to the outdoor products companies worldwide) but expensive, OMNI-TECH (developed by COLUMBIA, USA, for its own brand only) Use), FIRST-TEX (developed by FBA International Group of the United States, used only in designated brands, used by the first outdoor brand in the United States in 2014), TEXPORE (developed by JACKWOLFSKIN, Germany, for its own brand only), JCT (China Jiujia-Boshen Development, open to the outside world, inexpensive and inexpensive) and other professional materials manufacturers or well-known outdoor brand companies exclusively developed professional waterproof and breathable materials.
