Abstract

The invention discloses a method for processing a faux suede membrana dermalis coating. The method comprises the following steps: (1) bottom layer rubber coating preparation, namely, evenly stirring 100 parts of polyurethane resin, 0.5-1 part of polyurethane thickening agent, 0.5-2 parts of melamine cross-linking agents, 4-10 parts of foam stabilizers and 1-3 parts of foaming agents and increasing the foaming size to 1-3 times, (2) facial layer rubber coating preparation, namely, evenly stirring 100 parts of coldness-resistant lightless coating adhesive, 5-10 parts of amidogen modified polysiloxane, 0.5-2 parts of cross-linking agents and color paste, (3) adopting a dry method to coat directly, increasing the dry weight of the bottom layer rubber coating by 5-8g / m2, using a planishing mill for calendaring, and increasing the dry weight of the facial layer rubber coating by 7-10g / m2. The method is simple in technology and feasible, improves the distortion and bending resistance, elasticity and softness of fabric, improves dry-wet friction firmness, wear-resisting performance and coldness resistance of the fabric, and does not influence in index of the fabric.

Description

technical field [0001] The invention belongs to the technical field of finishing of textile fabrics, and specifically relates to a treatment method for a suede fabric coating, so as to improve the anti-distortion and bending performance of the suede fabric coating, and improve the softness, elasticity and durability of the product . Background technique [0002] In the textile industry, the fabric imitating the fur style of animal suede is called imitation suede. In the cloth market, suede has become a common name for various imitation suedes. The suede mentioned below is this kind of imitation suede. fleece fabric. Suede is a kind of fabric that uses natural fibers or natural fibers and superfine fibers to interweave cloth to make the surface of the fabric form a smooth and smooth hairiness style. Its unique style is very popular among consumers. [0003] Suede-like dry film coating is to use direct coating equipment to apply the coating glue on the surface of the fabric ...
