A method for crushing wool fiber scale tips

Abstract

The invention discloses a wool fiber flake tip crushing method, which is characterized in that the wool fiber is immersed in a suspension of inorganic particles, fully contacted by the action of ultrasonic waves, and the inorganic particles are loaded on the surface of the fiber; the loaded inorganic particles are The wet wool fiber is laid flat on the tray in the vacuum microwave treatment equipment for vacuum microwave treatment; the microwave treated wool fiber is immersed in water and cleaned by ultrasonic vibration; the cleaned wool fiber is dried. In the present invention, the inorganic particles are loaded on the inner side of the tip of the wool fiber scale through ultrasonic vibration, so that the microwave radiation energy is concentrated on the tip of the fiber scale during the microwave treatment process, thereby avoiding damage to the mechanical properties of the wool fiber. The directional friction effect of the wool fiber treated by the method is reduced, the mechanical properties are unchanged, and the anti-shrinkage performance and dyeing property of the fiber are improved. The method has the advantages of simple process, energy saving, environmental friendliness and broad market prospect.

Description

technical field [0001] The invention relates to a treatment method for removing scale tips on the surface of wool fibers, and belongs to the technical field of anti-shrinkage treatment of plush fiber products. Background technique [0002] The surface of wool fiber is covered with dense scales, and the scale layer can protect the internal tissue of wool and resist external mechanical and chemical erosion. However, the existence of the scale layer will not only cause felting of wool products, but also form a dyeing barrier, which makes it difficult for the dye solution to wet when wool fibers are dyed, hinders the adsorption and diffusion of dyes, and makes dyeing difficult. [0003] At present, physical methods such as ultrasonic waves, microwaves, plasma treatment, and corona discharge can be used to remove the wool scale layer; and chemical methods such as ozone, oxidation, chlorination, biological enzymes, resins, and persulfate treatment. However, the alkali resistance ...

AI Technical Summary

Problems solved by technology

However, the alkali resistance of wool fiber is poor, and it will also cause damage to the main body under strong acid conditions. Many organic solvents are harmful to wool fiber. In addition, chemical methods are easy to directly dispose of the entire wool scale and destroy the surface scale structure of wool fiber.

Compared with chemical methods, the application of physical technology can reduce the amount of chemicals used and the generation of dyeing and finishing sewage, but the treatment effect is often not as good as chemical methods
