Problems solved by technology

[0004] In the traditional concept, direct dyes have serious discoloration in the face of various physical and chemical reactions, and the molecular structure is damaged, and the color fastness is greatly reduced. It is generally considered unsuitable for dyeing high-end denim fabrics.
[0005] To sum up, the denim fabric preparation industry now has single or dull colors, unstable shades or lack of three-dimensional effect; large pollution emissions; either has a white core effect but poor color fastness, or has good color fastness but no white core effect. question

Abstract

The invention discloses a preparation process of a fadeless jean fabric, and belongs to the technical field of jean fabric preparation. The main technical problems that an existing jean fabric is single in color and not bright in color, or under the condition that the color is bright, the special white core effect of jean is not achieved, pollution emission is high, and color fastness is poor aresolved. The invention provides the preparation method of the jean fabric which not only can be used as high-grade clothes, but also has fashion sense of jean under certain conditions, and is high in color fastness, rich in color and low in pollution emission. The influence of the direct dye on the jean fabric is improved by mainly utilizing the cooperation of a cationic modifier, a penetrant, salt, a color fixing agent, a dry and wet rubbing fastness improver and a washing and dyeing textile process, so that the direct dye can be applied to the preparation of the jean fabric, and the fadelessjean fabric is prepared.

Description

technical field [0001] The invention relates to a preparation process of non-fading denim fabric, belonging to the technical field of denim fabric preparation. Background technique [0002] Denim fabric is a fabric that is widely used in daily leisure life. Common denim fabric preparation processes are pretreatment, wetting, dyeing, washing, weaving, and finishing. The dyes used for dyeing are generally reactive dyes or sulfur dyes. [0003] For a long time, the main color of denim has been dominated by indigo, and it has the disadvantages of serious pollution, huge emissions and single color. The commonly used sulfur-dyed varieties have dull shades and poor fastness. Black is the most important color spectrum, followed by blue, olive and brown. There are few color spectrums, and it is difficult to meet people's needs for colorful colors in modern society. At the same time, the color and light of sulfur dyes are not stable enough, and the reproducibility is poor, so it is...
