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

[0019] The manufacturing method of nitroxyl-based solvent-based polyamide resin artificial leather is to use nitroxyl-based solvent-based polyamide resin to prepare a finishing slurry, and then apply the finishing slurry to the surface of the artificial leather base cloth. Technology Laminate the nitroxyl-based solvent-based polyamide surface layer on the wet-process semi-finished product of artificial leather, and then get the dyed polyamide artificial leather through pad dyeing treatment.

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

[0021] Nitroxyl solvent-based polyamide resin 100 parts

[0022] Dimethylformamide 100 parts

[0023] Acetone 80 parts.

Embodiment 2

[0025] The manufacturing method of nitroxyl-based solvent-based polyamide resin artificial leather is to use nitroxyl-based solvent-based polyamide resin to prepare a coating slurry, and then coat the coating slurry on the surface of the artificial leather base cloth. The solvent-based polyamide finishing slurry is applied to the surface of the dry semi-finished artificial leather, and then the dyed polyamide artificial leather is obtained through jigger treatment.

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

[0027] Nitroxyl solvent-based polyamide resin 100 parts

[0028] 80 parts of dimethylformamide

[0029] 60 parts of acetone.

Embodiment 3

[0031] The manufacturing method of nitroxyl-based solvent-based polyamide resin artificial leather is to use nitroxyl-based solvent-based polyamide resin to prepare a coating slurry, and then coat the coating slurry on the surface of the artificial leather base cloth. The solvent-based 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.

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

[0033] Nitroxyl solvent-based polyamide resin 100 parts

[0034] 80 parts of dimethylformamide

[0035] Acetone 100 parts.

Abstract

The invention relates to a manufacturing method of nitroxyl-based solvent type polyamide resin artificial leather. Coating slurry is prepared by using nitroxyl-based solvent type polyamide resin, then coats the surface of artificial leather base cloth and is dyed to obtain dyed polyamide artificial leather. The coating slurry comprises the following components in parts by mass: 100 parts of nitroxyl-based solvent type polyamide resin, 20 to 120 parts of dimethylformamide, and 20 to 120 parts of acetone. The nitroxyl-based solvent type polyamide resin is used as an artificial leather surface coating material, and can be dyed with dye, and the color effect of dye coloring can be obtained after dyeing, so that the product has the characteristics of bright color, high coating permeability, high surface color fastness and low color transfer performance.

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-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...
