A Study on Ultrasonic Technology in Silk Degumming

Article Preview

Abstract:

During the transmission of ultrasound, its great directionality, ubiquitous penetration and the ability to strengthen the diffusion, exchange and transfer of matter can help the treating fluid reach the crossing points of silk fabric. And the function of ultrasonic wave can make use of acoustic cavitation effect to produce impact on sericin layer at the crossing point, thus promoting the fragmentation and separation of sericin, improving the removal efficiency of sericin at crossing points and achieving uniform silk fiber degumming. The function of ultrasonic wave can cut down the time of process and avoid the damage of fibroin through controlling the temperature and dose of chemical agent.
