Abstract

The invention discloses a dyeing method of a wool / viscose blended fabric. The dyeing method comprises following steps: S01, the wool / viscose blended fabric is subjected to moistening; S02, dyeing is started at 44.5 to 45.5 DEG C; S03, a dyeing auxiliary, urea, and anhydrous sodium sulphate are added, and M minutes later, a dye is added; S04, N minutes later, the temperature of an obtained mixture is increased to 84.5 to 85.5 DEG C at a temperature rise rate of 1.5 DEG C / min; S05, dyeing is carried out for X minutes; S06, anhydrous sodium sulphate is added continuously, thermal insulation is carried out, and dyeing is carried out for X minutes; S07, the temperature of an obtained product is reduced to be lower than 70 DEG C, and the obtained product is washed; S08, acetic acid and a dye-fixing agent are added, and fixation is carried out for Y minutes; and S09, a washing agent is added for washing, and a finished product is collected. Color yield percentage of the wool / viscose blended fabric is consistent, and dyeing effect is improved.

Description

technical field [0001] The invention relates to a method for dyeing wool-viscose blended fabrics. Background technique [0002] Wool-viscose blended fabrics can be dyed with direct dyes and acid dyes in the same bath, mostly in weakly acidic dyeing baths. The process is simple and easy to control, but the color yield of wool-viscose blended fabrics is inconsistent, which affects the dyeing effect. Contents of the invention [0003] In view of the above problems, the present invention provides a method for dyeing wool-viscose blended fabrics, which makes the color yield of the wool-viscose blended fabrics consistent and improves the dyeing effect.
