The technology of ptfe waterproof and breathable membrane was first introduced from European and American countries. It has developed into many generations of products: the first generation, shoes, clothing, tents, and sleeping bags were first only covered with waterproof glue on the fabric in order to achieve waterproofing and windproofing. In order to achieve the purpose of waterproofing, products made of this material and technology can withstand a certain amount of water pressure, but they are absolutely not breathable and have poor waterproof and breathable properties.
The second generation, PU film, is a material with good water pressure resistance. By combining the product fabric with it, it can achieve better waterproof stability. Its high-end products may have some moisture permeability, but The effect is very unsatisfactory.
For example: KING-TEX is currently on the market.
The third generation, TPU film, is developed on the basis of PU film. It is better than PU film in terms of air permeability, moisture permeability and water pressure resistance. It is a waterproof and breathable film that replaces PU film. There are TING- TEX, KING-TEX, etc.
The fourth generation, ptfe waterproof and breathable membrane is the latest generation of waterproof and breathable materials. All the world’s leading manufacturers use this material, and combine it with their respective company’s R&D composite processing technology to develop different brands of EPTFE composite fabrics with their own specialties. Its waterproof and breathability are among the best today.
The main ones that have outstanding performance in the international market are: GORE-TEX (developed by Gore Company of the United States, open-ended and used by various outdoor products companies around the world), OMNI-TECH (developed by COLUMBIA Company of the United States, only for its own brand) Used), FIRST-TEX (developed by FBA International Group in the United States, only used in designated brands, the largest outdoor brand in the United States in 2014 is using this material), EVENT (developed by a professional waterproof and breathable material manufacturer that has rapidly emerged in recent years) , TEXPORE (developed by German JACKWOLFSKIN company, only for its own brand use) and other professional waterproof and breathable materials independently developed by international high-end material manufacturers or well-known outdoor brand companies.
