Abstract

The invention discloses imitation sheepskin ultrafine fiber polyurethane synthetic leather and a manufacturing method thereof. The manufacturing method comprises the following steps: (1) applying oil to raw base cloth A and drying to obtain base cloth B; (2) bonding a sizing agent of surface layer dry-method polyurethane resin to the base cloth B obtained in the step (2) through a polyurethane bonder by a release paper dry-method film-shifting and surface-making technology, and stripping release paper to obtain the imitation sheepskin ultrafine fiber polyurethane synthetic leather. According to the method, the moderately soft base cloth is selected, the base cloth subjected to oil application is high in softness and leather feel, and the surface-overlaid ultrafine fiber polyurethane synthetic leather obtained through a dry-method surface-making process is good in fold lines and smooth feel. The imitation sheepskin ultrafine fiber polyurethane synthetic leather provided by the invention is exquisite in fold lines and smooth in hand feel, has a very good genuine leather feel and successfully solves the problem that exquisite fold lines and high softness of conventional imitation genuine leather ultrafine fiber synthetic leather cannot be compatible.

Description

technical field [0001] The invention relates to a superfine fiber polyurethane synthetic leather and a manufacturing method thereof, in particular to a sheepskin-like superfine fiber polyurethane synthetic leather and a manufacturing method thereof. technical background [0002] Genuine leather goods have always been regarded as a symbol of high-end leather goods. With the improvement of people's environmental protection requirements and the strengthening and deepening of animal protection awareness, the appeal to develop a high-simulation artificial leather that can replace genuine leather is becoming stronger and stronger. Microfiber polyurethane synthetic leather is a high-grade artificial leather developed on the basis of fully analyzing the microstructure and properties of natural leather. Its strength, chemical resistance, wrinkle resistance, abrasion resistance, processability and quality uniformity It is superior to genuine leather in terms of other aspects, and over...
