Abstract

The invention belongs to the field of synthetic leather and in particular relates to a production method of high-permeability furniture leather. The production method of the high-permeability furniture leather comprises the following steps: preparing a dry-process semi-finished product by using a release paper transfer film method; then coating the surface of the dry-process semi-finished product with polyether resin slurry with excellent crosslinking degree, drying and shaping patterns; then fitting the surface of the dry-process semi-finished product with the textured surface of a single-sided brushing fabric, drying again, and curing to prepare the high-permeability polyurethane resin synthetic leather. By virtue of the production method of the high-permeability furniture leather, the technical problem that the conventional PU leather is impermeable can be solved; the production cost is low; the production is convenient to control; the production period is short; meanwhile, the finished leather has full patterns, and is soft in hand feeling and stable in quality.

Description

Technical field [0001] The invention relates to a production method of polyurethane synthetic leather, in particular to a production method of high permeability polyurethane synthetic leather. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the smoke and air permeability of sofas and other furniture. At present, the preparation methods of polyurethane synthetic leather are mainly divided into two categories: [0003] (1) Dry method: [0004] Synthetic leather dry process production uses polyurethane resin (PU) to coat release paper with various textures, after drying and pasting, the base fabric (knitted fabric, non-woven fabric, etc.) is used as the base material for bonding and drying The dry process, and then the printing process, makes it comparable to real leather in terms of touch, toughness and appearance. [0005] (2) Wet method: [0006] The method includes the following steps: firstly cover a ...
