Abstract

The invention relates to a high-strength environment-friendly ultrafine fiber product with low deformation resistance, which is characterized in that the high-strength environment-friendly ultrafine fiber product with low deformation resistance is manufactured by adjacently attaching a plurality of non-woven base materials A to non-woven base materials B in sequence, and the non-woven base materials A and the non-woven base materials B consist of polybutylene terephthalate and polyamide polymer respectively, wherein the weight ratio of the polybutylene terephthalate to the polyamide polymer is 10-90:90-10 percent. After being impregnated by a polyurethane coating, the base materials are solidified, washed, dried and softened to obtain a high-strength divisional ultrafine fiber base material with low deformation resistance; and the divisional ultrafine fiber artificial leather base material can be attached to form a high-strength divisional ultrafine fiber leather product with low deformation resistance through post processing.

Description

technical field [0001] The invention relates to a high-strength environment-friendly superfine fiber product with low deformation resistance and a manufacturing method thereof. A high-strength segmented microfiber leather product made of a non-woven fabric as a base material and a manufacturing method thereof. Background technique [0002] Known superfine fiber artificial leather mostly uses solvent or alkaline solution to carry out weight reduction and splitting treatment. With Taiwan Patent Application No. 76102732 "Novel manufacturing method of superfine fiber and its processed fabric", the periphery of its fiber has A layer of polyester film is formed. When opening the fibers, the surrounding polyester film must be dissolved with lye before the fibers can be split by mechanical fiber splitting. However, this manufacturing process often causes serious water pollution. . [0003] U.S. Patent No. 6517938 and Japanese Patent No. 2003105679, their production methods all use...
