Abstract

The present invention discloses a dyeing process of an anti-staining nylon color strip fabric cheese, and relates to the technical field of textile dyeing. The dyeing process comprises the following steps of (1) preparing a dye liquor; (2) performing dyeing; (3) preparing a color fixation liquid; (4) performing color fixation; and (5) carrying out cleaning. Dyeing of the nylon cheese is completedby virtue of combination of dyeing of an active dye and two times of color fixation, the dye-uptake reaches almost 100%, the nylon cheese after being dyed is high in color fastness, an anti-staining effect is achieved during processing of the color strip fabric, and especially the problem of staining after water washing of the color strip fabric can be avoided effectively, thereby ensuring the appearance quality of the color strip fabric.

Description

Technical field: [0001] The invention relates to the technical field of textile dyeing, in particular to a dyeing process for cheeses of anti-staining nylon color strip fabrics. Background technique: [0002] Polyamide fiber is commonly known as nylon, referred to as PA, and its basic composition is aliphatic polyamide linked by amide bonds. The most prominent advantage of polyamide fiber is that its wear resistance is higher than other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabrics can greatly improve its wear resistance. [0003] With the improvement of living standards, people have higher and higher requirements for the performance of textiles, and the requirements for various performances of textile dyeing have become increasingly stringent. Efforts to improve the fixation rate of dyes and the color fastness of textiles, as well as to reduce the amount of dyeing wastewater, have become current research ...
