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.

Embodiment 1

[0027] The microwave urea modification treatment method for wool comprises the steps of: soaking the wool in a finishing solution containing 200g / L urea for 20 minutes, two dipping and two rolling, the excess rate is 70%, and then putting the wool fabric in a microwave device for irradiating for 1 minute , with a microwave power of 300W, fully washed in hot water at 50°C, washed in cold water, and finally dried.

[0028] Microwave / urea treatment increased the roughness of the wool fiber surface by SEM photos after modification treatment.

Embodiment 2

[0030] The microwave ammonia salt modification treatment method of wool comprises the steps of: soaking the wool in a finishing solution containing 0.4mol / L ammonia water and 8g / L sodium chloride for 20 minutes, two dipping and two rolling, the excess rate is 70%, and then Put the woolen fabric into a microwave device for 3 minutes and irradiate it with a microwave power of 300W, fully wash it in hot water at 50°C, wash it in cold water, and finally dry it.

Embodiment 3

[0032] The microwave hydrogen peroxide modification treatment method of wool comprises the steps of: soaking the wool in a finishing solution containing 30ml / L hydrogen peroxide, 0.7% sodium silicate and 0.2% anhydrous sodium carbonate for 20 minutes, two dipping and two rolling, and the excess rate is 70% %, and then put the wool fabric into a microwave device for 3 minutes of irradiation, the microwave power is 700W, fully washed in hot water at 50°C, washed in cold water, and finally dried.

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...
