项目摘要
Investigations have been made on the fine structure and the physical properties of the blend film and fiber composed of silk sericin from bombyx mori and poly- (vinyl alcohol)(PVA). The results are as follows.1. The microphase separated structure was found in the blend film and fiber by an microscope. The interfacial region between two phases consists of PVA-sericin complex.2. The complexz is formed strongly by the interaction between NH groups of sericin and OH groups of PVA chains at the region of sericin content of about 10 to 20 wt%, yielding the increase of fracture strain and the decrease of elongation at high temperature.3. Sericin in the blend fiber protects against the orientation of amorphous PVA chains with drawing, so that the thermal shrinkage of the blend fiber is very small.4. Moisture regain of the blend film increases with increasing hydrophilic sericin , which mainly consists of an amorphous region. The complex region, however, keeps away the increase of water content.5. The dyeing by an acid dyes becomes easily with increasing sericin content.
本文研究了桑蚕丝胶与聚乙烯醇(PVA)共混膜及纤维的微细结构和物理性能。研究结果如下:1.显微镜观察发现共混膜和纤维中存在微相分离结构。两相界面区由PVA-丝胶复合物组成.在10 ~ 20wt%的范围内,丝胶中的NH基团与PVA链上的OH基团之间形成了强烈的复合物,导致了高温下断裂应变的增加和伸长率的降低.共混纤维中的丝胶蛋白阻止了PVA无定形链在拉伸过程中的取向,使共混纤维的热收缩率很小.共混膜的回潮率随亲水性丝胶含量的增加而增加,亲水性丝胶主要由无定形区组成。而复合区则抑制了土壤含水量的增加.酸性染料的染色性随丝胶含量的增加而变好。
