Description

technical field [0001] The invention relates to the field of textiles, in particular to a preparation method of an ultra-fine denier nylon fiber, an ultra-light fabric and an ultra-light jacket. Background technique [0002] Nylon fiber fabric has the characteristics of sweat absorption, light weight, good toughness, good resilience, acid and alkali resistance, etc., and is one of the main raw materials of clothing materials. The thickness of nylon fiber can be characterized by monofilament fineness. Generally, chemical fibers with a monofilament fineness of about 1 dtex are called fine denier fibers, and chemical fibers with a single fiber fineness of about 0.5 dtex are called ultra-fine denier fibers. Fine denier nylon fibers can give the fibers a silky luster, smooth and soft feel, and are very popular. For this reason, fine denier or ultra-fine denier nylon fibers are very important. However, none of the existing technologies can reasonably make nylon fibers fine or ult...
