Problems solved by technology

But also because of this reason, the surface tension of wool is increased, the hydrophilicity is enhanced, the dye solution is easier to penetrate, the color is dyed faster during the dyeing process, and the cloth surface is more prone to dyeing defects such as colored flowers.

Abstract

The invention relates to a method for dyeing shrinkproof wool fabrics. The method comprises the steps: injecting water into a dyeing machine, adding the shrinkproof wool fabrics, carrying out cycling running for 5-10 min, then adding a wool detergent, sodium carbonate and anhydrous sodium sulphate, and heating to 60-70 DEG C, carrying out heat preservation for 20 min, cooling, then discharging water, and washing with water; and injecting water into the dyeing machine, then successively adding a bath smoothing agent, anhydrous sodium sulphate, a leveling agent and acetic acid with the amount 1 / 2 of the total amount, circulating, then adding an aqueous solution of a dye, carrying out cycling running, then heating to 75 DEG C, then adding the remaining acetic acid, heating to 90 DEG C, carrying out heat preservation for 30-60 min, then cooling to 80 DEG C, and washing. The method can effectively prevent generation of uneven dyeing and other defects, is simple and effective in process, and has a good effect in actual production.

Description

technical field [0001] The invention belongs to the field of dyeing methods for knitted fabrics, in particular to a dyeing method for shrink-resistant wool fabrics. Background technique [0002] Wool is one of the important raw materials of the textile industry. Wool products have the characteristics of full hand feeling, good warmth retention and comfortable wearing. However, there is a scale layer on the surface of the wool fiber. During the washing process of the wool fabric, due to the directional friction effect of the scale layer, the appearance changes such as size reduction, hairy and thickening, and blurred lines will seriously affect the wearability of the fabric. [0003] Shrink-resistant wool is produced under such needs. Compared with ordinary wool, the surface scale layer of shrink-proof wool is destroyed, thus avoiding the felting problem caused by directional friction. But also because of this reason, the surface tension of wool is increased, the hydrophili...
