Embodiment 1

[0013] Grey fabric: polyester-cotton blended jersey

[0014] Auxiliary: Dyeing, terminating and degreasing and bathing agent DM-1380 produced by Wuxi Demei Company

[0015] Dye: Navy blue dye

[0016] Bath ratio: 1:8

[0017] Process: the grey fabric is put into the dyeing bath, then the degreasing and bathing agent is added to the dyeing bath, and then the dye is added to the dyeing bath, and then the temperature is raised to 125°C for dyeing.

[0019] Grey fabric: polyester-cotton blended jersey

[0020] Auxiliary: Dyeing, terminating and degreasing and bathing agent DM-1380 produced by Wuxi Demei Company

[0021] Dye: black dye

[0022] Bath ratio: 1:8

[0023] Process: the grey fabric is put into the dyeing bath, then the degreasing and bathing agent is added to the dyeing bath, and then the dye is added to the dyeing bath, and then the temperature is raised to 135℃ for dyeing.

Embodiment 3

[0025] Grey fabric: polyester-cotton blended jersey

[0026] Auxiliary: Dyeing, terminating and degreasing and bathing agent DM-1380 produced by Wuxi Demei Company

[0027] Dye: Navy blue dye

[0028] Bath ratio: 1:8

[0029] Process: The grey fabric is put into the dyeing bath, then the degreasing and bathing agent is added to the dyeing bath, and then the dye is added to the dyeing bath, and then the temperature is raised to 130°C for dyeing.

Abstract

The invention discloses a dyeing method of a polyester cotton blended fabric. The method comprises steps of: putting grey cloth into a dye bath; adding one bath deoiling agent in the dye bath; adding dye into the dye bath; heating to 125-135 DEG C; and dyeing. According to the dyeing method of the polyester cotton blended fabric of the invention, a pre-treatment is not needed to carry out emulsification on oil stain and impurities on the grey cloth in the dye bath, so as to guarantee dyeing quality.

Description

Technical field [0001] The invention relates to the field of textile processing, in particular to a method for dyeing polyester-cotton blended fabrics. Background technique [0002] Polyester is widely used in various textiles due to its high strength, good resilience, excellent abrasion resistance, good dimensional stability, and good wrinkle resistance. Among them, polyester-cotton blended fabric is the most common, and polyester-cotton blended fabric combines the above two The advantages of this kind of fiber, the clothes made are not deformed, have bones, are soft, moisture-absorbing, wear-resistant, comfortable to wear, and are very suitable for making workwear fabrics. Due to the difference in chemical structure and performance between polyester and cotton fibers, two different types of dyes are needed. Polyester is dyed with disperse dyes, and cotton fiber is dyed with reactive dyes. Usually, disperse dyes are dyed under acidic conditions, while reactive dyes are Dyeing u...
