摘　　要：采用有机溶剂6号轻汽油通过浸出法工艺处理丝绵,利用现代分析技术测试了丝绵的性能和结构变化。研究发现:与未处理丝绵相比,处理后丝绵白度、压缩率及回弹率明显提高,而其含油率、含胶率、回潮率和断裂强度则降低。处理后丝绵含油率小于5%,压缩率大于42%,回弹率大于90%,回潮率小于12%,处理后丝绵微观结构未发生变化。结果证明该脱胶除油工艺方法是合理可行的。6#light gasoline was used to treat silk floss through leaching method. The changes in the structure and property of silk floss were tested with modern analysis technique. It is found that compared with untreated silk floss,whiteness,compression ratio and elastic recovery of the treated silk floss improve obviously,while the oil content,glue content,moisture regain and breaking strength reduce. After treatment,the oil content is less than 5%; the compression ratio is more than 42%; the elastic recovery rate is more than 90%; the moisture regain is less than12%. After treatment,microstructure of silk floss remains unchanged. The results show degumming and oil removal method is rational and feasible.
