摘　　要：选择酒石酸为生丝脱胶剂,通过正交试验与验证试验优化用酒石酸对生丝脱胶的工艺条件。对生丝脱胶效果影响最大的因素是脱胶温度,其次是酒石酸浓度和脱胶时间,后2个因素对脱胶效果的影响程度相仿。确定生丝用酒石酸脱胶的最佳工艺条件为:酒石酸质量浓度6 g/L,脱胶温度100℃,脱胶时间45 min。在此优化工艺条件下,可获得完全脱胶的生丝,且减少生丝的断裂强力和断裂伸长率损失。试验结果提示酒石酸是一种良好的生丝脱胶剂,用酒石酸脱胶更有利于保持生丝的力学性能。The present study used tartaric acid as degumming agent to optimize technological conditions for degumming raw silk of mulberry silkworm by means of orthogonal experiment and verification experiment.It was found that the biggest influencing factor was degumming temperature,followed by tartaric acid concentration and degumming time.The optimal technological condition for degumming with tartaric acid was as follows： tartaric acid mass concentration 6 g /L,degumming temperature 100 ℃,and degumming time 45 min.Under this condition,completely degummed raw silk could be obtained.Meanwhile,loss of breaking strength and breaking elongation rate of the raw silk was reduced.The above results indicate that tartaric acid is a good raw silk degumming agent,and degumming using tartaric acid is favorable to maintain mechanical properties of the raw silk.
