For protecting the environment, reducing pollution and saving energy, the technical process of silk degumming and sericin extracting was investigated in this paper. Boiling degumming and icing extracting mathod were adopted in the experiments. The optimal technological conditions of raw silk degumming and sericin extracting were obtained by using the orthogonal experimental design. The experimental results showed that the optimal technical parameters of silk degumming were the concentration of anhydrous sodium carbonate 2%, heating time 60min, bath ratio 1:30, as well as, for sericin extracting, they were pH value 7, temperature -24°C, freezing time 12h. On these conditions, the degumming loss percentage and the recovery rate were 26.1% and 75.5% respectively.
