The main component of microfiber in a microfiber jacket is polyamide fiber. According to the data, the composition and structure of polyamide fiber is simpler than that of protein fiber, and it only has carboxyl and amino groups at the end of the molecular chain. In the middle of the molecular chain, there are a large number of carbon chains and amide groups without side chains.

　　Therefore, the microfiber jacket should first use acid hydrolysis and enzymatic hydrolysis technology to chemically modify the microfiber, open its amide bond, increase its active group, and then use natural The retanning, filling, fatliquoring and dyeing technology of leather enables macromolecular tanning agents to be filled between microfibers to improve its water vapor permeability and other physical properties. Microfiber jackets make microfiber base fabrics and real leather blanks feel close.

　　Microfiber jackets feel that as a new synthetic leather processing method, it is currently feasible to introduce leather wet processing and finishing technology into the production of microfiber synthetic leather. However, with the improvement of the microfiber processing technology level, it is necessary to fundamentally improve the manufacturing process of the microfiber base cloth, so that the microfiber base cloth itself is close to the physical properties and feel of the natural leather blank.

　　The microfiber jacket reminds us to pay special attention to the fact that the development of microfiber synthetic leather must be combined with tanning, dyeing and finishing, shoemaking and furniture processing to form a one-stop shop and improve the overall development capability. The vitality of fine fiber synthetic leather.
