Abstract

The invention relates to a production method of synthetic leather, and specifically relates to a production method of degradable soybean fiber synthetic leather. The production method comprises the following steps of 1) selecting soybean fiber with excellent physical properties, blending the selected soybean fiber and chemical synthetic leather fiber according to a certain proportion to obtain a mixture, and carrying out the processes of cotton carding, cotton lapping, needling and design fixing on the mixture to obtain soybean fiber non-woven fabrics, and 2) carrying out a synthetic leather production process by a wet method and a synthetic leather production process by a dry method to obtain soybean fiber synthetic leather finished products. The production method changes a present situation that 100% of fiber of traditional synthetic leather is checamical synthetic fiber, and introduces degradable biological soybean fiber into traditional synthetic leather thereby reducing a contentof chemical fiber. The production method is beneficial to reduce environmental pollutions, and has the characteristics of low carbon and environmental protection. On the premise of no change of mechanical properties, synthetic leather produced by the production method has cashmere-like soft hand-feel belonging specially to soybean fiber, silk-like soft luster, cotton-like heat-retention property,good skin affinity and observable bacteriostasis functions.

Description

technical field [0001] The invention relates to a production method of synthetic leather, in particular to a production method of degradable soybean fiber synthetic leather. Background technique [0002] At present, in the field of synthetic leather, most of the non-woven fabrics with 100% chemical synthetic fibers (polyester, nylon) are used as the base. Due to the difficulty of degrading chemical fibers, they are easy to pollute the environment, and most chemical fibers are due to their The incompatibility to the skin makes it uncomfortable to wear. Soybean fiber belongs to the category of regenerated plant protein fiber. It uses oil-pressed soybean meal as raw material, and uses bioengineering technology to extract globulin in soybean meal. branching, copolymerization, and blending to make a protein spinning solution with a certain concentration, change the spatial structure of the protein, and form it by wet spinning. It has cashmere-like soft feel, silk-like soft lust...
