用丝素蛋白整理棉织物，研究丝素蛋白降解时间及浓度对整理后棉织物性能的影响，确定最佳的丝素降解时间和浓度。在此基础上与TiO2复配，研究整理剂中TiO2含量对棉织物性能和结构的影响。结果表明：最佳丝素蛋白降解时间为120min，丝素浓度（质量分数）为1．63％；此时将丝素与Ti02复配，当Ti02质量分数为0．35％时，可使织物折皱回复角比纯丝素整理提高8．68％，紫外防护系数达到42．9，抗紫外性能达到二级。X射线衍射分析表明，丝素蛋白整理可降低棉纤维的结晶度，并使棉纤维由纤维素I向纤维素II转变，而Ti02整理可提高棉纤维的结晶度。

The influence of the silk fibroin degradation time and concentration on the performance of the finished cotton fabric have been studied and got the suitable silk fibroin degradation time as well as the concentration by using the pure silk fibroin to finish cotton fabric. Then the content of TiO2 in the complexed finishing on the performance and structure of cotton fabric can be researched on the basis. The results showed that the best silk fibroin degradation time is 120 min, the silk fibroin density is 1.63%, then 0.35% TiO2 is added, the fabric wrinkle recovery angle increased by 8.68%, the UV protection factor reach to 42.9 achieving the secondary, comparing with the pure silk fibrin finishing. X-ray diffraction showed that the crystallinity degree of cotton fibres was reduced and cellulose I changed to cellulose II by silk fibroin finishing, but the crystallinity was improved by TiO2 finishing.
