Problems solved by technology

[0002] At present, the dyeing of polyester-cotton blended fabrics mainly adopts the two-bath method. Due to the different dyeing properties of the fibers, two different types of dyes are used to dye the two fibers respectively. The polyester components in the fabric need to be dyed with disperse dyes, and the cotton components need to be dyed. Direct dyeing, usually disperse dyes are dyed under acidic conditions, while direct dyes are dyed under neutral conditions, so polyester-cotton blended fabrics need to be dyed twice, that is, two baths are required for dyeing. The whole dyeing process is long and has many procedures. Waste of energy, and secondary dyeing is easy to cause uneven dyeing, high production costs, affecting the economic benefits of enterprises

Abstract

The invention, belonging to printing and dyeing area for silk cloth, relates to a dyestuff alkali-washing dyeing method for polyester mixed textile dispersedly and directly. Said method is that under the condition of 7<PH<9 alkali, direct and dispersal dye of alkali resistivity are use as dyeing for polyester textile. Under the lower alkali condition, polyester fibre after dyeing can avoid shortcoming of a mass of flaw generated by lixiviation of slurry, oils and other catabolite in acidic bath. It can conquer damnification of dyeing and fibre under the circumstance of high temperature, pressure and alkali. The invention can conserve energy, decrease cost and improve production efficiency.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to an alkaline one-bath dyeing method for polyester-cotton blended fabrics with disperse and direct dyes.
