With the development of science and technology, as well as the development of leisure, sightseeing and leisure industry, sportswear or mountaineering wear are also becoming more popular. However, when the body is sweating, the sweat will enter the clothes fiber, when the internal drainage function of the clothes fiber is lower than the sweat. Accumulated speed will cause sweat to not easily evaporate and accumulate in the clothes, causing the skin to feel wet and uncomfortable, so there is a need for improvement.

One of the objects of the present invention is to provide a textile which is subjected to a foam coating process to impart moisture and water repellency to textiles.
