Abstract

The invention discloses a disperse reactive dye one-bath two-step dip dyeing method for polyester cotton fabric. The method comprises the following steps: S1, pretreatment: padding a polyester cotton fabric to be dyed in a finishing liquid, conducting two dipping and two rolling, pre-drying at 60-80 DEG C, baking at 120-140 DEG C, washing with cold water and drying; S2, polyester dyeing: immersing the polyester in a disperse dye, insulating at 65-75 C, and insulating at 110-130 DEG C; S3, cotton dyeing: adding a quaternary ammonium salt cationic etherifying agent, stirring for reaction, adding a reactive dye, insulating at 70-80 DEG C, adding a dyeing auxiliary, insulating, adding soda ash, and insulating at 60-100 DEG C; and S4, posttreatment: conducting an initial washing, soaping and post washing. The disperse reactive dye one-bath two-step dip dyeing method for polyester cotton fabric has the advantages of simple process, easy industrial implementation, wide dye application, uniform coloration, high fixation rate and good levelness.

Description

technical field

[0001] The invention relates to the technical field of dyeing, in particular to a one-bath two-step exhaust dyeing method of disperse reactive dyes for polyester-cotton fabrics. Background technique

[0002] 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, the production efficiency is low, the water, electricity, steam consumption is large, the sewage discharge is large, and because the wet processing time is long, it is easy to make the cloth surface fluffy and affect the fabric feel, so that the product quality and the economic benefits of the enterprise are reduced.

[0003] The existing disperse / reactive dye one-bath dyeing method replaces the disperse / reactive dye two-bath two-step...
