Abstract

The invention discloses a dispersion-reduction dyeing process for a cotton-polyester blended fabric. The dispersion-reduction dyeing process comprises a disperse dyestuff treating procedure and a vat dye treating procedure which are successively carried out. The disperse dyestuff treating procedure comprises dyeing, reduction cleaning, washing and pickling; the vat dye treating procedure comprises dip padding with a vat dye suspension, dip padding with a reducing solution, steaming, oxidation, soaping, hot washing and drying; in the disperse dyestuff treating procedure, a disperse dyestuff microcapsule method is used for dyeing; and in the vat dyestuff treating procedure, vat dye wet rapid-steaming pad dyeing process is employed. The dispersion-reduction dyeing process for the cotton-polyester blended fabric has the advantages of good level dyeing effect, small chromatic aberration and high color fastness, and is simple in process.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a process for disperse reduction dyeing of polyester-cotton blended fabrics. Background technique [0002] The dyeing of polyester-cotton blended fabrics mostly adopts the one-bath two-step method of disperse / reactive dyes in actual production. The dyeing process is relatively simple, easy to operate and easy to control, but the color fastness of reactive dyes, especially the chlorine fastness Difference. Vat dyes have the advantages of complete chromatogram, bright color after dyeing, good color fastness to sunlight, washing and chlorine bleaching. Dyeing polyester-cotton blended fabrics by disperse / reduction method can improve the deficiency of reactive dyes and meet customers' demands for high-quality products. Among them, vat dyes are usually dyed by exhaust dyeing, and the commonly used methods are suspension method and leuco method. Vat dye suspension dyeing ...
