摘　　要：蓖麻蚕作为一种野蚕,其结成的蚕茧与桑蚕茧相比有很多不同之处。文章将蓖麻蚕茧与桑蚕茧各自分为外观特征区别明显的三个层次:外层(茧衣)、中层(茧层)和内层(蛹衬),分别对其结构和强力、防紫外、抗菌等防护性能进行对比研究。蓖麻蚕茧由于茧丝模量高、结构致密,拉伸过程中存在明显的二次断裂现象,其三层茧丝的强力变化与桑蚕茧存在类似的规律。蓖麻蚕茧的抗紫外线能力高于桑蚕茧,对金黄色葡萄糖球菌的抑菌能力与桑蚕茧相当,对大肠杆菌的抑菌能力略低于桑蚕茧。综合来看,蓖麻蚕茧表现出比桑蚕茧更强的保护能力。通过对不同茧层结构性能差异与茧层之间的构造进行研究分析,为非织造仿生材料的开发提供借鉴。As a kind of wild species,eri silkworm make cocoons with a lot of difference compared with Bombyx mori cocoon.In this paper,eri silkworm cocoons and Bombyx mori cocoon are classified into three categories in terms of the obvious differences in appearance:outer layer(cocoon coat),middle layer(cocoon layer)and inner layer(cocoon lining).A comparative study is performed on the structure and strength,UV resistance,antibacterial and protective properties.There exists a significant secondary fracture during tensile process due to high modulus of eri silkworm cocoon lining and its dense structure.The strength variation of eri silkworm cocoon silk in three layers is similar to that of Bombyx mori cocoon.The UV resistance of eri silkworm cocoon is higher than that of Bombyx mori cocoon,and its antibacterial ability against S.aureus is equivalent to that of Bombyx mori cocoon,its antibacterial ability against E.coli is slightly lower than that of Bombyx mori cocoon.On the whole,eri silkworm cocoon exhibits stronger protection ability than Bombyx mori cocoon.The research and analysis of the difference in structure and properties of different cocoon layers and the structure between cocoon layers are expected to provide reference for the development of nonwoven bionic materials.
