Abstract

The invention relates to a dyeing-facilitating sulfonyl polyurethane suede artificial leather manufacturing method. Dyed polyurethane suede artificial leather is obtained by preparing coating slurry by using sulfonyl solvent type polyurethane resin, then coating the surface of suede artificial leather base cloth with the coating slurry, and carrying out dyeing treatment. The coating slurry is prepared from the following components in parts by mass: 100 parts of the sulfonyl solvent type polyurethane resin, 20 to 120 parts of dimethyl formamide and 20 to 120 parts of acetone. As an artificial leather surface coating material, the sulfonyl solvent type polyurethane resin can be dyed through a dye; after being dyed, the sulfonyl solvent type polyurethane resin can achieve a color effect of the dye; therefore, a product has the characteristics of bright color, high coating permeability, high surface color fastness and low color migration property.

Description

technical field

[0001] The invention belongs to the technical field of preparation methods of polyurethane suede artificial leather, and in particular relates to a method for manufacturing sulfonyl polyurethane suede 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 color paste, tone...
