The performance of the material of the trousers can be basically divided into two categories: one is the microporous fabric of EPTFE laminating film. At present, there are only three kinds of GORE-TEX, DENTIK and EVENT in China. Its waterproof and breathable function is to laminate a microporous film on the outer fabric of the garment to volatilize its own sweat while blocking the rain; the other is a hydrophilic fabric with PU or TPU coating (or lamination). In addition to the above three, all other brands are in this category. Its function is achieved by a non-porous waterproof layer and a hydrophilic molecular chain structure.
The comparison between these two types of materials: EPTFE fabrics have the advantage of being waterproof and breathable, especially at low temperatures (the snow mountain climbers wear such garments thanks to this feature). ),Wide range of applications. The disadvantage is that the washability is slightly worse and the price is higher; the PU fabric has the advantages of good durability and low price. The disadvantage is that the gas permeability is poor, especially when the ambient temperature is low, the gas permeability is lowered due to the instability of the material properties, and the application range is not as wide as the former.
