Abstract

The invention belongs to the field of textile printing and dyeing processing, and in particular relates to the dyeing and finishing process of highly washable T / C blended woven tooling fabrics, for the use of regenerated color masterbatch as polyester raw material, and the use of T / C without PVA slurry in the textile process Dyeing and finishing of blended tooling fabrics, the technological process: pre-treatment ‑ dyeing ‑ post-finishing ‑ finished product. The textile process of the present invention does not use the slurry containing PVA, which reduces the difficulty of the pre-treatment process, reduces the concentration of the working solution in the deboiling process by about 25% on average, and reduces the COD value of the first washing tank by more than 40%. The effect of energy saving and emission reduction; the use of masterbatch as polyester raw material, there is no process of dyeing disperse dyes during dyeing, which improves production efficiency, and also reduces the use of hydrosulfite and NaOH in the reduction cleaning process; the finished product has excellent anti-corrosion Pilling 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...
