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