Abstract

The invention discloses a dyeing method for mycose modified wool fiber, and belongs to the field of modified shell fabrics. The method comprises the following steps: step one, washing the mycose modified wool fiber with a washing agent, washing out with clear water, and drying; step two, adding a dye into water at the temperature of 70 to 80 DEG C to form a dye liquor, soaking the mycose modified wool fiber into the dye liquor for carrying out water-bath heating, wherein the bath ratio is (60 to 70): 1; step three, raising the temperature to 100 DEG C at the heating rate of 0.5 to 1 DEG C per minute, and carrying out a heat preservation reaction 2; step four, quickly cooling, and washing out with water; and step five, drying with hot air, wherein the drying temperature is 72 to 73 DEG C. Cationic starch in the invention is a cationic compound, and has extremely good appetency with wool under an acidic condition, so that the dyeing degree is higher, and the fiber is unlikely to fade. Mycose plays an absorption role for an anionic dye, and the dye is further dispersed into the interior of the fiber more easily, so that the color fastness of the wool fiber is improved.

Description

technical field [0001] The invention belongs to the field of modified fabrics, in particular to a method for dyeing trehalose-modified wool fibers. Background technique [0002] Wool fiber is a deformation of sheep's skin. It has excellent warmth retention property and is mostly used in autumn and winter clothing, but it is very easy to be eaten by insects. The most important wool fiber for textile is sheep wool, which is usually called wool, or wool fiber, or wool for short. Wool covers the surface of the sheepskin and is densely clustered together. In each small bundle of hairs, there is a guide hair with a thicker diameter and deeper hair follicles. Other thinner wools grow around the guide hairs to form a clump. The fibers in the hair bundles have the same shape, similar length and fineness, high growth density, and more sweat fat to make the fibers adhere to each other, forming a shape that is basically the same up and down, and looks like a flat-topped hair bundle fro...
