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.
