Abstract

The invention relates to a manufacturing method for water-soluble phosphate polyamide resin artificial leather. The manufacturing method comprises the following steps: preparing coating slurry from water-soluble phosphate polyamide resin; then coating the surface of artificial leather base cloth with the coating slurry; and carrying out dyeing so as to obtain dyed polyamide artificial leather, wherein the coating slurry comprises, by mass, 100 parts of water-soluble phosphate polyamide resin, 20 to 120 parts of dimethyl formamide and 20 to 120 parts of acetone. Since the water-soluble phosphate polyamide 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 preparation methods of polyamide resin artificial leather, and in particular relates to a method for manufacturing phosphoric acid-based 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 ...

Examples

Embodiment 1

[0018] The manufacturing method of phosphoric acid-based water-soluble polyamide resin artificial leather is to use phosphoric acid-based water-soluble polyamide resin to configure the coating slurry, and then apply the coating slurry to the surface of the artificial leather base cloth. Technology The phosphoric acid-based water-soluble polyamide surface layer is attached to the wet-process semi-finished product of artificial leather, and then the dyed polyamide artificial leather is obtained through pad dyeing treatment.

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

[0020] Phosphate-based water-soluble polyamide resin 100 parts

[0021] 20 parts of water.

Embodiment 2

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

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

[0025] Phosphate-based water-soluble polyamide resin 100 parts

[0026] 60 parts of water.

Embodiment 3

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

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

[0030] Phosphate-based water-soluble polyamide resin 100 parts

[0031] 40 parts of water.
