1. Outdoor sportswear belongs to functional clothing, which is very different from ordinary clothing. Fireproof clothing, waterproof clothing, dustproof clothing, etc. It belongs to the category of professional clothing, but it can be used by the public in life. According to the characteristics of outdoor sports, this kind of clothing has the following basic requirements: 1. It has certain wear resistance and tear strength, that is, it must be very strong. 2. Have certain warmth to prevent maintaining body temperature under extreme conditions. 3. waterproof; 4. It is breathable. Especially the latter two, waterproof and breathable are contradictory in themselves, so it is necessary to solve this problem in a special way. At present, no single structural material has all the above functions, so the research and development of composite -3 laminated adhesive technology is a clothing technology developed to solve the above needs. The outermost layer is wear-resistant and tear-resistant, the middle layer is waterproof and breathable, and the inner layer is warm and protective. The purpose of glue pressing is to ensure the waterproofness of slit.
Gore is recognized as the best waterproof and breathable man-made film in the world at present, with waterproof performance of 20000mm and air permeability of 8000- 10000gm/m2/24hr. Widely used in aerospace, outdoor, engineering and other fields, it is currently the top waterproof and breathable material. However, this kind of film has a weakness, that is, it is easy to be damaged and has poor wear resistance.
At present, the market price of a pair of Gore shoes is more than 1000 yuan, and the real three-layer Gore outdoor clothing is more than 2000 yuan.
