Problems solved by technology

[0004] At present, disperse / reactive dyes are usually dyed by disperse / reactive two-bath method, dyeing polyester first, and then dyeing cotton. However, due to the long wet processing time, it is easy to make the cloth surface fuzzy and affect the feel of the fabric, resulting in a decline in product quality and economic benefits. , and will produce a large amount of sewage, affecting the environment

Abstract

The invention disclose a uniform-color CVC (Chief Value of Cotton) Dansibo fabric dyeing method, which includes the following steps: a CVC Dansibo fabric is pretreated, and is then immersed in dyeing liquor, the bath ratio is 1:30-40, temperature is increased to 85 DEG C to 95 DEG C, and is kept for 15 to 25 minutes, temperature is then increased to 135 DEG C to 145 DEG C, and is kept for 40 to 60 minutes, temperature is decreased to 85 DEG C to 95 DEG C, water washing is carried out, soaping is carried out, and water washing and drying are then carried out. The uniform-color CVC (Chief Value of Cotton) Dansibo fabric dyeing method is easy to operate, the dyeing period is short, environment pollution is less, dyeing is uniform, colorability is good, color fastness to soaping is good, and color fastness to rubbing is good.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a method for dyeing CVC Dansbury fabrics with uniform color and luster. Background technique [0002] CVC fabric is a fabric with only two components of polyester and cotton, when the cotton content is equal to or exceeds 50%. CVC fabric has good wear resistance and wrinkle resistance, and is not easy to deform, especially in the case of machine washing. [0003] Polyester is generally dyed with disperse dyes, while cotton fibers can be dyed with reactive dyes, direct dyes, and vat dyes. Therefore, the dyeing of polyester-cotton blended fabrics generally uses dyeing processes such as disperse / reactive dyes, disperse / direct dyes, and disperse / vat dyes. In order to make the finished product have better color fastness, dyeing vividness and simpler dyeing process, disperse / reactive dyes are usually used to dye polyester-cotton fabrics. [0004] At present, disperse / reactive ...
