Abstract

The present invention discloses paint dyeing process for dyeing blended fabric of gossamer with wool, cotton, bast, etc. The blended gossamer fabric material is pre-treated with polyamine polyol as multifunctional compound and dyed with special dyeing adhesive via optimized technological process to obtain destination product. The technological process is simple and low in power consumption, and the dyed blended gossamer fabric product has soft hand feeling, low formaldehyde content, high color fastness and stable product quality. The present invention is suitable for industrial production.

Description

Technical field [0001] The invention belongs to the technical field of fabric dyeing and finishing, and particularly relates to a dyeing method of Tencel blended fabric. Background technique [0002] The tencel blended fabric of the present invention is a knitted product with wide application. [0003] Tencel (Tencel fiber) and cotton, wool, and linen can be respectively composed of Tencel / cotton, Tencel / wool, Tencel / linen and other blended fabrics. Usually, the dyeing process uses reactive dyes. Due to the high swelling and adsorption of Tencel The fast speed leads to inconsistent color absorption of different fibers, and it is easy to produce color blur and color difference. Most Tencel blends are dyed separately with more than two dyes to solve the problem that the two fibers cannot be dyed at the same time. There is a difference in color during dyeing. Color and color difference, the quality of the dyed product is unstable, the hand feel is poor, and the color fastness is not...
