| 摘 要： | 将胶原蛋白和聚乙烯醇(PVA)分别溶解后复合纺丝,制得胶原蛋白/PVA复合纤维,对复合纤维的可纺性、力学性能和结构进行了初步探索。结果表明,胶原蛋白和PVA复合纺丝,具有较好的可纺性,复合纤维经过热拉伸、热定型和缩醛化处理后,纤维强度、模量和伸长率分别达到了2.3cN/dtex,30.69cN/dtex,20.12%;结晶度较高为70.57%;水中软化点由缩醛化前的89℃提高到110℃。通过扫描电镜照片观察复合纤维,未发现两相结构,胶原蛋白和PVA结合较好。

| Abstract: | A polyvinyl alcohol/collagen composite fiber can be produced from a spinning solution containing dissolved collagen and polyvinyl alcohol via composite spinning. The spinnability, mechanical properties and structure of the composite fiber were studied. The results showed that the spinning solution of polyvinyl alcohol and collagen showed good spinnability while composite spinning. After heat drawing, heat setting and acetalization, the composite fiber had strength 2. 3 cN/dtex, modulus 30.69 cN/ dtex, elongation 20. 12% and crystallinity 70.57%. The softening point in water was increased up to 110℃ from 89℃ after acetalization. According to SEM photographs, no two-phase structure was observed which indicated that collagen and polyvinyl alcohol integrated with each other very well. |
