preparation example Construction

[0012] Some embodiments of the present invention provide a method for preparing a woolen woolen fabric with cashmere feel and luster, which includes: chlorinating the woolen woolen fabric with a chlorinating agent; The fabric is reduced by a reducing agent; the woolen woolen fabric after the reduction treatment is subjected to alkali washing; after the alkali-washed woolen woolen fabric is neutralized with acid, soft wet brushing is carried out on a wet brushing machine.

[0013] Specifically, woolen woolen fabrics that have been spun into woolen fabrics will affect their touch and fabric contact with the human body due to the wool oil in the wool blending process, the strength agent, the antistatic agent and paraffin wax in the spinning process, etc. its own gloss. Therefore, it is necessary to remove dirt and sweat stains before chlorination. Therefore, in some embodiments of the present invention, the removal of dirt and sweat stains is performed by adding a leave-in agent...

Embodiment 1

[0035] In the first step, add woolen woolen fabric and water to be processed into the piece dyeing machine, and the mass ratio of water and woolen woolen fabric in the piece dyeing machine is 30:1. Then add Montelai-2703 non-cleaning agent and run for 8-12 minutes, wherein the amount of Montelai-2703 non-cleaning agent added is 1.5% of the mass of woolen woolen fabric.

[0036] In the second step, add half of the chlorinating agent to the piece dyeing machine and run for 8 minutes, then add the other half of the chlorinating agent and run for 18 minutes. Wherein, the consumption of chlorinating agent is 4% of the quality of woolen fabric, and chlorinating agent is sodium dichloroisocyanurate. During the reaction, the reaction temperature was controlled at 20° C., and the pH value was adjusted to 3 by adding formic acid before adding the chlorinating agent.

[0037] The third step is to weigh 4% of the reducing agent of woolen wool fabric mass, dissolve it in water, add half o...

Embodiment 2

[0044] In the first step, add woolen woolen fabric and water to be processed into the piece dyeing machine, and the mass ratio of water and woolen woolen fabric in the piece dyeing machine is 40:1. Then add Montelai-2703 non-cleaning agent and run for 12 minutes, wherein the amount of Montelai-2703 non-cleaning agent added is 2.5% of the woolen woolen fabric quality.

[0045] In the second step, add half of the chlorinating agent to the piece dyeing machine and run for 12 minutes, then add the other half of the chlorinating agent and run for 22 minutes. Wherein, the consumption of chlorinating agent is 6% of the quality of woolen fabric, and chlorinating agent is sodium dichloroisocyanurate. During the reaction, the reaction temperature was controlled at 25° C., and the pH value was adjusted to 4 by adding formic acid before adding the chlorinating agent.

[0046] The third step is to weigh 6% of the reducing agent of the woolen woolen fabric mass, dissolve it in water, add h...

Abstract

The invention discloses a woollen fabric having hand feeling and gloss as cashmere and a preparation method thereof. The preparation method includes: chlorinating the woollen fabric with a chlorinating agent; reducing the chlorinated woollen fabric with a reducing agent; alkaline-washing the woollen fabric after the reduction; adding acid to the alkaline-washed woollen fabric for neutralization, and performing softening wet-brushing on a wet-brushing machine. Through the steps of chlorination, reductive cleaning, alkaline washing, neutralization and wet brushing, degraded proteins in a scale layer of denuded wool fibers are removed, so that the fabric has smooth and flat surface and can regularly reflect light beam and shows gloss; therefore, the woollen fabric has a soft hand feeling andis improved in gloss, has an anti-shrinking effect, can solve problems of itching feeling, stiffness, roughness and the like, and has the feeling and gloss as pure cashmere.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a woolen wool fabric with cashmere feel and luster and a preparation method thereof. Background technique [0002] In recent years, with the continuous introduction of high-count yarns and thin fabrics, especially cool styles, a good foundation has been laid for the transformation of woolen sweaters into underwear and shirting. But one of the problems it faces is that when it is washed many times, it is very easy to feel and shrink in the process of repeated washing. The second problem is that the itching, stiffness and roughness of wool itself are exposed when worn next to the body. Contents of the invention [0003] The first object of the present invention is to provide a woolen woolen fabric with cashmere feel and luster, which can improve the felting shrinkage during washing and the itching of existing woolen woolen fabrics. [0004] The second object of the present inv...
