Abstract

The invention belongs to the field of textile printing and dyeing, and particularly relates to a dyeing and finishing process of a highly-washable T / C blended woven workwear fabric. Regenerated colormaster batches serve as polyester raw materials, dyeing and finishing are implemented by the T / C blended woven workwear fabric without PVA (polyvinyl alcohol) slurry in the spinning process, and a technological process of dyeing and finishing includes the steps: pretreating; dyeing; post-finishing; fished product preparing. According to the process, the slurry containing PVA is omitted in the spinning process, pretreating difficulty is reduced, the working fluid concentration of a desizing and scouring process is averagely reduced by about 25%, a COD (chemical oxygen demand) value of dischargeof a first rinsing tank is reduced by 40% or more, the process has obvious energy conservation and emission reduction effects, the color master batches serve as the polyester raw materials, a dyeingprocess of disperse dyes is omitted in the dyeing process, production effects are improved, sodium hydrosulfite in the reducing cleaning processes and use of NaOH are reduced, and a finished product has excellent pilling resistance and wrinkle resistance.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing processing, and in particular relates to a dyeing and finishing process of highly washable T / C blended woven tooling fabric. Background technique [0002] T / C blended woven fabric has a very wide market at home and abroad as tooling and protective fabrics. It fully integrates the excellent properties of polyester fiber such as high strength, wrinkle resistance, wear resistance and cotton fiber's moisture absorption and breathability, and has become the mainstream of tooling fabrics. Varieties, especially after various dyeing and finishing functional processing, are used in various industries. However, with the advancement of science and technology and the change of production and lifestyle, people's requirements for the performance and durability of tooling fabrics are also increasing, and their standards are getting higher and higher, such as the washability of fabric performance, espec...
