Abstract

The invention discloses a pretreatment technology for disperse dye printing of a polyester-cotton blended fabric. The pretreatment technology comprises the work procedures of desizing, bleaching, washing, and shaping, wherein multi-effect compound enzyme and a disperse dye alkaline dyeing protection additive are added in the work procedure of desizing and bleaching. The pretreatment technology has the advantages that desizing, bleaching and dyeing pretreatment are completed in a one-bath process, so that the technical process is shortened, and the operation is simplified; not only can paste, cellulose, stains, oil spots and the like on the polyester-cotton blended fabric be effectively removed for dyeing preparation, but also the polyester-cotton blended fabric can be endowed with an excellent coloring property in advance; the pretreatment technology is low in water and electricity consumption, has the energy conservation and emission reduction effects, conforms to the development trend of the printing and dyeing industry, and has a broad market prospect.

Description

technical field [0001] The invention relates to the technical field of pretreatment of textiles, in particular to a pretreatment process for printing polyester-cotton blended fabrics. Background technique [0002] Traditional knitted and woven polyester-cotton blended fabrics need to undergo high-temperature pre-treatment before dyeing to remove textile oil stains, stains, sizing, etc., especially to remove cotton seed husks and short fibers on cotton fibers to improve the smoothness of the fabric. Washing and neutralization process after pre-treatment process, to avoid the pre-treatment of knitted fabrics to avoid oil removal, impervious scouring, unevenness and unclean alkali removal, resulting in white spots, blooms and uneven slivers on the cloth surface during printing. And other issues. The traditional pretreatment process is long, consumes a lot of resources such as water and electricity, and removes a large amount of sewage and pollutants at the same time, which doe...
