| 中文摘要: |
| 采用双氧水预处理并结合蛋白酶-脂肪酶工艺细化羊毛纤维.通过正交试验分别确定了羊毛双氧水预处理的条件和蛋白酶-脂肪酶处理工艺条件,并进行了生物酶细化处理羊毛的对比试验.结果表明采用双氧水预处理并蛋白酶-脂肪酶细化处理羊毛后,羊毛纤维鳞片层受到一定程度的破坏,纤维的直径降低约2.3μm,断裂强力保持率达到94.8%. |
| 英文摘要: |
| Pretreatment of wool fibers with hydrogen peroxide,refinement with enzymes were studied in this paper.Orthogonal experiments were adopted to analyze the pretreatment process with hydrogen peroxide and refinement process with protease-lipase treatment process.Comparison experiments of different enzymes on wool fiber were also carried out.Results showed that by adopting the protease-lipase refinement process,the scales of wool fibers were destroyed partially,diameters decreased about 2.3 microns and tensile strength remains to 94.8 percent. |
