Abstract

The invention relates to a method for manufacturing carboxylic solvent type polyamide resin artificial leather. The method comprises the following steps: preparing coating slurry with carboxylic solvent type polyamide resin, applying the coating slurry to the surface of an artificial leather substrate and dyeing, and performing dyeing treatment to obtain dyed polyamide artificial leather. The coating slurry comprises the following ingredients in parts by weight: 100 parts of carboxylic solvent type polyamide resin, 20-120 parts of dimethyl formamide and 20-120 parts of acetone. Carboxylic solvent type polyamide resin is taken as a coating material on the surface of the artificial leather, so that carboxylic solvent type polyamide resin can be dyed by a dye, the color effect of dye coloring can be achieved after dyeing, and a product has the characteristics of bright color, good coating permeability, high surface color fastness and small color mobility.

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 carboxyl-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 colo...

Examples

Embodiment 1

[0019] The carboxyl-based solvent-based polyamide resin artificial leather manufacturing method is to use the carboxyl-based solvent-based polyamide resin to configure the finishing slurry, and then coat the finishing slurry on the surface of the artificial leather base cloth. The carboxyl-based solvent-based polyamide surface layer is pasted on the wet-process semi-finished product of artificial leather, and then dyed polyamide artificial leather is obtained through pad dyeing treatment.

[0020] Finishing paste comprises the following components by mass:

[0021] Carboxylic solvent type polyamide resin 100 parts

[0022] Dimethylformamide 100 parts

[0023] Acetone 80 parts.

Embodiment 2

[0025] The carboxyl-based solvent-based polyamide resin artificial leather manufacturing method is to use the carboxyl-based solvent-based polyamide resin to configure the coating slurry, and then coat the finishing slurry on the surface of the artificial leather base cloth. The amide coating slurry is applied to the surface of the semi-finished artificial leather dry process, and then dyed polyamide artificial leather is obtained after jigger dyeing.

[0026] Finishing paste comprises the following components by mass:

[0027] Carboxylic solvent type polyamide resin 100 parts

[0028] 80 parts of dimethylformamide

[0029] 60 parts of acetone.

Embodiment 3

[0031] The carboxyl-based solvent-based polyamide resin artificial leather manufacturing method is to use the carboxyl-based solvent-based polyamide resin to configure the coating slurry, and then coat the finishing slurry on the surface of the artificial leather base cloth. The amide coating surface layer is coated on the surface of the semi-finished artificial leather base cloth, and then dyed polyamide artificial leather is obtained through air-flow dyeing treatment.

[0032] Finishing paste comprises the following components by mass:

[0033] Carboxylic solvent type polyamide resin 100 parts

[0034] 80 parts of dimethylformamide

[0035] Acetone 100 parts.
