Abstract

The invention discloses a dispersing bath method dyeing process of polyester-cotton microcapsule disperse dye. The dispersing bath method dyeing process comprises a microcapsule dispersing dyestuff processing process and a dyestuff reduction processing process which are sequentially performed, wherein the microcapsule dispersing dyestuff processing process comprises microcapsule dispersing dyestuff dyeing, primary water washing, soaping and post water washing; the dyestuff reduction processing process comprises the steps of dyestuff reduction, dyeing, water washing, oxidation, soaping, hot washing and drying; in the dyeing process of the microcapsule disperse dye, polyester-cotton fabrics are subjected to dye liquid soaking according to a bath ratio of 1:(10-20). A recipe of dye liquid comprises 1 to 3 (owf) percent of microcapsule dispersing dyestuff, 1 to 2g / L of pH buffering agents and 1 to 2g / L of levelling agents. The dispersing bath method dyeing process of polyester-cotton microcapsule disperse dye has the advantages of good uniform dyeing degree, small color differences and high color firmness; in addition, the process is simple.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a disperse-bath dyeing process of polyester-cotton microcapsule disperse dyes. Background technique [0002] The dyeing of polyester-cotton 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, is poor. . Since vat dyes have the advantages of complete chromatogram, bright color after dyeing, and good color fastness to light, washing, and chlorine bleaching, the use of dispersion / reduction method to dye polyester-cotton blended fabrics can improve the shortcomings of reactive dyes. , to meet customer demand 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. Among them, ...
