Description

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