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.

Embodiment 1

[0018] The manufacturing method of glycol water-soluble polyurethane resin artificial leather is to use glycol water-soluble polyurethane resin to configure finishing slurry, and then coat the finishing slurry on the surface of artificial leather base cloth. The glycol water-soluble polyurethane surface layer is attached to the artificial leather wet-process semi-finished product, and then the dyed polyurethane artificial leather is obtained through pad dyeing treatment.

[0019] Finishing paste comprises the following components by mass:

[0020] 100 parts of glycol water-soluble polyurethane resin

[0021] 20 parts of water.

Embodiment 2

[0023] The manufacturing method of glycol water-soluble polyurethane resin artificial leather is to use glycol water-soluble polyurethane resin to configure the coating slurry, and then coat the coating slurry on the surface of the artificial leather base cloth. Polyurethane finishing slurry is applied to the surface of dry-process semi-finished artificial leather, and then dyed polyurethane artificial leather is obtained through jigger dyeing.

[0024] Finishing paste comprises the following components by mass:

[0025] 100 parts of glycol water-soluble polyurethane resin

[0026] 60 parts of water.

Embodiment 3

[0028] The manufacturing method of glycol water-soluble polyurethane resin artificial leather is to use glycol water-soluble polyurethane resin to configure finishing slurry, and then coat the finishing slurry on the surface of artificial leather base cloth. The polyurethane coating surface layer is coated on the surface of the semi-finished artificial leather base cloth, and then the dyed polyurethane artificial leather is obtained through air-flow dyeing treatment.

[0029] Finishing paste comprises the following components by mass:

[0030] 100 parts of glycol water-soluble polyurethane resin

[0031] 40 parts of water.

Abstract

The invention relates to a manufacturing method for water-soluble glycol polyurethane resin artificial leather. The manufacturing method comprises the following steps: preparing coating slurry from water-soluble glycol polyurethane resin; then coating the surface of artificial leather base cloth with the coating slurry; and carrying out dyeing so as to obtain dyed polyurethane artificial leather, wherein the coating slurry comprises, by mass, 100 parts of water-soluble glycol polyurethane resin, 20 to 120 parts of dimethyl formamide and 20 to 120 parts of acetone. Since the water-soluble glycol polyurethane resin is used as a coating material for the surface of artificial leather, dyeing with dyes can be carried out; and after dyeing, dye coloring effect can be obtained, and the produced artificial leather has the characteristics of a brilliant color, good permeability of a coating, high surface color fastness and small color migration.

Description

technical field [0001] The invention belongs to the technical field of polyurethane resin artificial leather preparation methods, and in particular relates to a method for manufacturing glycol water-soluble polyurethane 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 pa...
