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
The present invention relates to a kind of production method of Synthetic Leather, particularly a kind of production method of high-permeability Synthetic Leather.
Background technology
Along with improving constantly of living standard, people require more and more higher to the saturating cigarette of the furniture such as sofa, permeability.At present, Synthetic Leather its preparation method is mainly divided into two classes:
(1) dry method:
Synthetic leather dry production is coated in the release liners of various lines with polyurethane resin (PU), after drying, upper paste with base cloth (knitted cloth, nonwoven fabric etc.) for base material carry out fitting, the processing procedure such as oven dry, then through printing treatment, make it in sense of touch, toughness and in appearance, is enough to the corium that matches in excellence or beauty.
(2) wet method:
The method comprises the steps: first uniform fold one deck PU resin on textile fibre cloth, being immersed by the textile fibre cloth being coated with PU resin is equipped with in the coagulating basin of water again, when PU tree resin layer is in half curdled appearance, the figuratum mould of surface engraving is utilized to carry out embossing process on PU tree resin layer, then textile fibre cloth is taken out, enter in rinsing bowl, make its further slaking shaping, namely obtain the PU synthetic leather that surface has space pattern.
Although adopt wet method can obtain the synthetic leather with gas permeability, poisture-penetrability, continuous poriferous Rotating fields, the cycle of wet-layer preparation is longer.The present invention adopts dry process to have excellent polyurethane resin synthetic leather that is ventilative, smoke performance thoroughly, solve traditional PU and remove from office air-locked technical problem, and its production cost is low, be convenient to control.
Summary of the invention
The object of the present invention is to provide a kind of production method of high-permeability furniture leather, for achieving the above object, present invention employs following technical scheme:
A production method for high-permeability furniture leather, comprises the steps:
(1) release liners is selected, at described release liners surface uniform coating polyurethane cover slurry, epithelium namely obtained to be transferred after oven dry; Select raising base cloth, at the matte even spread polyurethane sticking layer slurry of described raising base cloth, the adhesive layer on described epithelium and described base cloth is fitted after drying, release liners is peeled off and obtains dry method semi-finished product; The weight of described polyurethane sticking layer slurry and polyurethane cover slurry consists of:
