Abstract: Summary: This study aim is to investigate the impact of urea on mulberry silk degumming of papain, by the changes of silk degumming rate. The results indicated: The urea may promote effectively the raw silk papain degum under the higher concentration, reduce amount of papain degummed by a larger degree，cause papain degum temperature broad. Namely: urea play a catalytic role on silk degumming of papain. According to this experimental result, if taking urea as the raw silk papain degum promoter, is necessary to study further more.
