Manufacturing method of sulfonyl-like solvent type polyamide resin artificial leather

Abstract

The invention relates to a manufacturing method of sulfonyl-like solvent type polyamide resin artificial leather. The method is characterized in that coating slurry is prepared through ulfonyl-like solvent type polyamide resin and then coats the surface of a base artificial leather cloth, and then the base artificial leather cloth is subjected to dyeing treatment so as to obtain the dyed polyamide artificial leather, wherein the coating slurry comprises the following components in parts by mass: 100 parts of sulfonyl-like solvent type polyamide resin, 20-120 parts of dimethylformamide, and 20-120 parts of acetone. According to the method, sulfonyl-like solvent type polyamide resin is used as the surface coating material of the artificial leather, and the dyeing processing can be carried out through dye; the dyed color effect can be obtained after the dyeing treatment. Therefore, the product has the characteristics of being bright in color, high in coating permeability, high in surface color fastness, and low in color migration performance.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of polyamide resin artificial leather, and in particular relates to a method for manufacturing a sulfonyl-based solvent-type polyamide resin artificial leather which is easy to dye. Background technique [0002] The artificial leather with dye coloring effect on the surface is bright in color and high in transparency. It is popular in fashion products such as bags and women’s shoes. However, traditional synthetic leather is usually colored by pigment, which cannot achieve the effect of dye coloring. Although it can The manufacturing method of adding dye water coloring agent to the coating material is used to obtain the dye coloring effect, but this manufacturing method will bring serious color migration, poor color fastness, high cost and other problems, which restrict the use of the product. [0003] In the traditional synthetic leather manufacturing process, it is necessary to add co...

Problems solved by technology

[0004] Coloring substances such as dyes are combined to give different colors to the finished leather, but the coloring of the coating feels hard, and once the coloring formula is determined, the coating presents a single color, the gloss and color are monotonous, and there is no layering such as depth, light and shade, new and old.
