Problems solved by technology

The molecular structure of chemical fiber itself is tight, and disperse dyes are generally used, which are dyed under high temperature and high pressure, and the color fastness is high; while the structure of natural fibers is loose, direct dyes and reactive dyes are mostly used, and the color fastness is relatively poor.

Abstract

The invention discloses a high-fastness suit fabric dyeing process and relates to pure wool fabrics. The high-fastness suit fabric dyeing process comprises the following steps of S1, pretreatment, S2,dyeing including heating reactive dye solution to 76-82 DEG C and holding the temperature for 50-60 min, then adding in ammonium hydroxide to regulate the PH to 8-9 for treatment for 10-20 min, thencooling down to 50-60 DEG C, adjusting the PH to 4.5-5 for treatment for 8-10 min, and sequentially performing cold water washing, soaping, cold water washing and drying, wherein the active dye solution is composed of, on weight the fabric, 2-3% of reactive dyes, 2-3% of acetic acid, 1-2% of low-temperature additives, 2-3% of ammonium sulfate and 0.1-0.2% of gadolinium chloride, S3, fixation including immersing the dyed fabric into dye-fixing solution at 40-60 DEG C for treatment for 12-25 min, wherein the dye-fixing solution is composed of, on weight the fabric, 2-4% of dye-fixing agent, andS4, cleaning. During the dyeing process, gadolinium ions can be complexed with amino and carboxyl of wool fiber as well carboxyl and amino of dye macromolecules to improve the dye uptake as well as the wool dyeing fastness and the mechanical performance.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a high color fastness dyeing process for suit fabrics. Background technique [0002] A suit is a type of clothing, which has the characteristics of crisp appearance and smooth lines. The commonly used fabrics are wool, cotton and linen, chemical fiber and so on. Dyeing is the process of chemical or physical chemical combination of dyes and fibers, or the formation of insoluble colored substances on fibers. Color fastness refers to the degree of fading of dyed fabrics under the action of external factors (extrusion, friction, washing, rain, etc.) during use or processing, and is an important indicator of fabrics. [0003] Due to the different structures of natural fibers and chemical fibers, the types of dyes used in the two are different. The molecular structure of chemical fiber itself is tight, and disperse dyes are generally used, which are dyed under high temperature and high pressure, a...
