Investigating the Process Conditions of Mulberry Silk Degumming with Papain
摘要
Abstract
This study investigated whether the degumming conditions had effect on mulberry silk degumming with papain. It used single-factor experiment to pick up the proper enzyme quality-concentration, temperature, time, pH value range, and then obtained optimized degumming conditions by orthogonal experiment. The results indicated that papain can effectively remove sericin. The results of the single-factor experiments showed the degumming loss rates and silk degumming strength loss rate are increasing with the enzyme concentration increase, pH value and temperature enhance and degumming time extension. The orthogonal experiment confirmed that the enzyme concentration is the main factor impacting on the degumming loss rate, the time of degumming is the major factor of affecting the force loses. Considered degumming loss rate and breaking strength loss rate, two better craft conditions of mulberry silk degumming are: one is papain quality concentration: 3 g/L, pH:6, temperature:85℃, time:60 min; the other is papain quality concentration:3 g/L, pH:8, temperature:65 ℃, time:90 min.关键词
