This study was investigated on the effect of degumming of cocoon shell, raw silk yarn and grey silk crepe by use of Papain, comparing with soap, soda and soap-soda. The obtained results may be summarized as follows : 1. Degumming loss, when the pretreatment was done, was completed by Papain more than by alkali. 2. Lousiness result of Papain degummed silk yarn was apt to be improved more than that of alkali degummed one. 3. As a result of tensile property test, elasticity and resilience of Papain degummed crepe were good compared to those of alkali degummed one. 4. Not only bending rigidity of Papain degummed crepe was reduced more than that of alkali degummed one but also hysteresis of bending moment was decreased in papain degummed crepe. 5. Handle of Papain degummed crepe was superior to that of alkali degummed one.
