A dyeing and finishing process for improving the splicing and mutual dyeing fastness of blended brushed fleece fabrics

Abstract

The invention relates to fabric dyeing and finishing processes, in particular to a dyeing and finishing method of a plush fabric. In the soaping step of a dyeing procedure of the blending plush fabric dyeing process, different soaping agents are used for fabrics prepared from different components, residual dye on different fabrics can be removed specifically, the surface dyeing of the fabrics reaches 4 levels or higher, and a basis is laid for the follow-up washing procedure; in the washing procedure, multiple water tank cleaning processes realizing slow temperature rising and slow temperature reducing are adopted, various special dispersants are adopted, distribution and combination of the dispersants in different water tanks are designed reasonably, a silicone oil aid can be dispersed uniformly, the situation that oil stains are produced and attached to cloth due to demulsification of silicone oil is effectively prevented, besides, surface dyeing granules produced on the surface of the fabric can be removed through multiple washing procedures, accordingly, the color fastness of the fabric is improved, and the cross staining color fastness of a textile spliced by fabrics in different colors is substantially improved.

Description

technical field The invention relates to a dyeing and finishing process for fabrics, in particular to a dyeing and finishing method for plush fabrics. Background technique In recent years, with the continuous innovation of style design, more and more splicing textiles have appeared on the market, such as splicing organic fabrics and knitted fabrics, splicing dark fabrics and light fabrics, and splicing dark fabrics and dark fabrics. Different tissue structures, different dyeing methods, and different color fastnesses after being spliced ​​together. These textiles are prone to mutual staining after washing. Dyes usually migrate from dark-colored parts to light-colored parts, resulting in light-colored fabrics. The parts are heavily stained, and because of the inconsistency in fiber composition and dyeing methods, when dark colors are combined with dark colors, such as bright red and purple, staining will also occur, which will affect the appearance of the textile. Therefore,...

Problems solved by technology

For special fabrics such as plush fabrics, in order to be easy to fluff, and to make the fur dense, supple, and shiny, it is necessary to add fluffing agents, fluffing agents, and softeners in the finishing. The above-mentioned additives all contain silicone components. Silicone It has a significant impact on the color fastness of blended fabrics. If the conventional dyeing and finishing process is used, the excellent splicing mutual color fastness cannot be achieved, that is, there will be serious mutual dyeing and collision between the spliced ​​plush fabrics of different colors. color phenomenon

At the same time, if the plush fabric is not handled properly in the subsequent washing process, the silicone oil will easily break and cause silicone oil spots on the surface of the fabric, which cannot be removed, resulting in the scrapping of the fabric

There is still no good solution to this problem
