Abstract

The invention discloses a mercerized-wool and cotton blended fabric dyeing method using a pomegranate bark plant dye. The mercerized-wool and cotton blended fabric dyeing method includes the followingsteps that 1, 1-3% by weight of sodium bicarbonate and 0.5-5% by weight of wetting agent are added into deionized water and then are uniformly stirred and mixed, mercerized-wool and cotton blended fabric is placed into a mixed solution to be heated to 50-70 DEG C to be processed for 20-30 min, and the bath ratio is 1:(20-30); 2, the pomegranate bark plant dye, dye mordant and a wetting agent areadded into deionized water and then are uniformly mixed and stirred to prepare a dye solution, the mercerized-wool and cotton blended fabric is placed into the dye solution, heating starts at 30-35 DEG C, the heating rate is kept at 2-3 DEG C/min, and the temperature is kept at 50-60 DEG C to carry out processing for 60-80 min, wherein the dye solution is acidic, the bath ratio is 1:(20-30), and the dye mordant is neodymium chloride and/or aluminum potassium sulfate dodecahydrate. By the adoption of the mercerized-wool and cotton blended fabric dyeing method using the pomegranate bark plant dye, neodymium chloride and/or aluminum potassium sulfate dodecahydrate is adopted as the dye mordant, the weakly acidic dyeing solution has little damage on mercerized wool during dyeing, and the dyeing rate and the color fastness are high.

Description

technical field [0001] The invention belongs to the technical field of dyeing wool fabrics, and in particular relates to a method for dyeing mercerized wool-cotton blended fabrics with pomegranate peel vegetable dyes. Background technique [0002] Wool fiber is an important raw material in the textile industry. Because of its excellent properties such as good hygroscopicity, warmth and comfort, soft and plump hand feeling, it has become one of the most high-end textile consumer products. Mercerized wool is the mercerized process of wool through the textile dyeing and finishing process. In China, the wool is generally treated with chlorination, oxidation or protease to destroy and peel off the wool scales on the surface of the wool, so as to reduce the friction coefficient between the forward and reverse movements of the wool. difference, resulting in wool with thread luster and hand. In mercerized wool and cotton blended fabrics, cotton fibers have excellent dye uptake, tha...
