Degradation of sericin (degumming) of Persian silk by ultrasound and enzymes as a cleaner and environmentally friendly process
چکیده انگلیسی

Degumming is a surface modification process of natural fibers such as silk. In this paper, the feasibility of degumming with ultrasonic, ultrasonic–soap, and ultrasonic–enzyme (alcalase, savinase, and mixtures of these enzymes) processes as cleaner and environmentally friendly surface modification techniques of Persian silk were investigated. The effectiveness of parameters such as sonication time, soap, ultrasound–enzyme, enzyme concentration, degumming time and enzymes mixture on silk degumming were studied. The evaluation of the data was carried out through the measurement of the weight loss, strength, and elongation of the samples. In addition, the enzymatic treatment improved the properties of silk yarn such as strength and elongation. The scanning electron microscope images were obtained for degummed silk samples. The findings of this research support the potential production of new environmentally friendly textile fibers.
