Method for microwave chemical modification treatment of wool

Abstract

The invention relates to a method for microwave chemical modification treatment of wool, which comprises: the wool is immersed in finishing liquid containing a chemical finishing agent for 20 to 40 minutes, is immersed twice and rolled twice, wherein the take-up ratio is from 70 to 120 percents, microwave irradiates 1 to 6 minutes, the power is from 300 to 700 W, and the wool is sufficiently washed by hot water of 50 to 60 DEG C, and dried. The invention has simple technology, energy source saving and environmental pollution reduction or prevention, and is suitable for industrial production. The wool after the modification processing of the invention can greatly improve the dyeing performance of wool-use active dyes and acid dyes on wool.

Description

technical field [0001] The invention belongs to the field of wool modification treatment, in particular to a microwave chemical modification treatment method of wool. Background technique [0002] Wool textiles have long been known for their luxury, elegance, and comfortable natural style, especially cashmere, which has the reputation of "golden fiber". During the dyeing process of cashmere, due to the hydrophobic dense scale layer on the surface of the wool fiber, it hinders the adsorption of dyes to the wool fiber and the internal diffusion, resulting in difficulty in wool dyeing. In order to improve the dyeing performance of wool, some physical or chemical methods are usually used to treat the scale layer to passivate or remove it. The conventional chemical boiling dyeing method pollutes the environment, and dyeing for a long time will easily cause yellowing or even gelation of the fiber, which will affect the feel and luster of the dyed product, and consume a lot of ene...

AI Technical Summary

Problems solved by technology

The conventional chemical boiling dyeing method pollutes the environment, and dyeing for a long time may easily cause the fiber to yellow or even gel, which affects the feel and luster of the dyed product, and consumes a lot of energy

Compared with chemical methods, although the application of physical denaturation technology can reduce the amount of chemical agents and the discharge of dyeing and finishing sewage, and realize anhydrous or non-aqueous dyeing, the treatment effect is often not as good as that of chemical methods.
