Problems solved by technology

[0003] The printing and dyeing industry has always adopted the two-bath two-step dyeing method of disperse / reactive dyes for dyeing polyester-cotton blended or interwoven fabrics, that is, dyeing polyester with disperse dyes-reduction cleaning-reactive dyes for over-dyeing cotton. The entire dyeing process takes more than 10 Hours, low efficiency, high energy consumption, large sewage discharge, and because of the long wet processing time, it is easy to make the cloth surface fuzzy and affect the fabric feel

Abstract

The invention discloses a high-precision flat shade cloth dyeing process, and relates to the technical field of textile dyeing. The dyeing process comprises the following steps of (1) dye liquor preparation; (2) dyeing; (3) water washing; and (4) fabric weaving. A polyester-cotton blended yarn is dyed by utilizing a disperse dye and an reactive dye, efficient dyeing of polyester fibers and cottonfibers is achieved, and the dyeing uniformity is ensured through the cooperative use of a leveling agent; the adhesive force of the dyes on the polyester-cotton fibers is enhanced through the additionof a color fixing agent, so that the color fastness of the prepared polyester-cotton fabric is improved; and the prepared high-precision flat shade cloth is suitable for being used as a processing fabric of middle and high-grade curtains, the shading rate is close to 100%, the soaping color fastness and the light fastness to sunlight are high, and the use quality of the curtains is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of textile dyeing, in particular to a dyeing process of a high-precision flat shading cloth. Background technique: [0002] High-precision flat shading cloth is usually used in the processing of curtains, and it is required to have good shading rate and color fastness. At present, polyester-cotton blended fabric is one of the commonly used processing fabrics for curtains, which has the dual characteristics of polyester and cotton. [0003] The printing and dyeing industry has always adopted the two-bath two-step dyeing method of disperse / reactive dyes for dyeing polyester-cotton blended or interwoven fabrics, that is, dyeing polyester with disperse dyes-reduction cleaning-reactive dyes for over-dyeing cotton. The entire dyeing process takes more than 10 Hours, low efficiency, high energy consumption, large sewage discharge, and because of the long wet processing time, it is easy to make the cloth surface f...
