文摘The treatment effect of ultrasonic on waste silk material was studied in this paper. The results show that Ultrasonic can emulsify the pupal fat and accelerate the dissolving of sericin. For high pupal fat containing material, high temperature, high pH value and long time which may result in damage to silk fibre are not required and different levels of sericin can be kept according to requirement in ultrasonic refining. In addition, silk fibres are swollen and the breaking elongation of silk fibre is increased on prolonged ultrasonic treatment. But the breaking tenacity is damaged slightly.
