Manufacturing method for water-soluble nitroxyl polyamide resin artificial leather

Abstract

The invention relates to a manufacturing method of nitroxyl-based water-soluble polyamide resin artificial leather, which is to use nitroxyl-based water-soluble polyamide resin to prepare coating slurry, then apply the coating slurry to the surface of artificial leather base cloth, and then undergo dyeing treatment to obtain The dyed polyamide artificial leather and the finishing paste include the following components in parts by mass: 100 parts of nitroxyl water-soluble polyamide resin, 20-120 parts of dimethylformamide, and 20-120 parts of acetone. Nitroxyl water-soluble polyamide resin is used as artificial leather surface coating material, which can be dyed with dyes. After dyeing, the color effect of dyeing can be obtained, so that the product has bright colors, good coating permeability, and surface color fastness. High, small color migration characteristics.

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 nitroxyl water-soluble 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 color pas...

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.
