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.
