Problems solved by technology

This process screens disperse and vat dyes, strengthens the reduction cleaning and soaping processes in the dyeing process, and pads the chlorine washing enhancer to improve the chlorine washing fastness of blue series polyester-cotton workwear fabrics. After the process is improved, it solves the problem Blue series polyester-cotton tooling products have the problem of low chlorine washing fastness, which avoids the defect of black and dark cloth surface caused by peroxidation, and improves the grade and added value of the product

Abstract

The invention relates to a long vehicle continuous pad dyeing process in the processing of dyeing and finishing of fabrics, in particular to a high chlorine washing fastness dyeing process of blue series polyster cotton tooling fabric. The dyeing process in the invention strengthens the reduction clearing and soaping working procedures by screening and dispersing and reactive dyes, and improves chlorine washing fastness of the blue series polyster cotton tooling fabric by padding chlorine washing promoter; after the technology is improved, the invention solves the problem of low chlorine washing fastness of the blue series polyster cotton tooling fabric, avoids the defect of blackening and darkening of cloth cover caused by overoxidation and improves product grade and additional value.

Description

technical field [0001] The invention relates to a long-car continuous pad dyeing process in the dyeing and finishing of textiles, in particular to a high-chlorine wash fastness dyeing process for blue series polyester-cotton tooling fabrics. Background technique [0002] The European and American markets have very high requirements for the color fastness of polyester-cotton workwear fabrics, with grade 4 or above for dry rubbing, grade 3 for wet rubbing fastness, grade 3 for white cloth staining, and grade 4 or above for washing color change, especially for medical tooling fabrics. The chlorine washing fastness is required to be above grade 4 of the AATCC standard. [0003] At present, a large number of workwear fabrics are dyed with disperse vat dyes. Pad dyeing with vat dye suspensions has strong adaptability to dyes, and has good level dyeing, penetration and fastness, especially chlorine fastness. Generally, vat dyes have excellent chlorine fastness, such as red F3B, ye...
