摘要(Abstract)：
为提高纤维素纤维和壳聚糖纤维的生物相容性能并保持纤维原有的力学机械强度,在其单纤维纺丝溶液中添加原胶原蛋白、丝素蛋白、甲壳素等,经湿法纺丝,考察了各种混合纤维的密度、直径、纤度、强度、伸长率等性能的变化。研究结果表明:壳聚糖纤维中混合原胶原蛋白后,纤维纤度增加,但对纤维的伸长和强度影响不大;当原胶原蛋白含量达10%时,纤维伸长率最大。纤维素纤维因添加了丝素后,强度、伸长下降,但添加第三组分甲壳素后表现出优异的机械性能。扫描电镜对混合纤维的形貌分析证实了生物材料与甲壳素、壳聚糖及纤维素间存在着良好的共混相容性,对纤维性能起到改善的作用。
In order to enhance the biocompatibility of the cellulose and the chitosan, and maintenance their original mechanical strength, the wet-spinning is used by the addition of tropocollagen, and silk fibroin to the single textile fiber. The density, diameter, titer, tenacity and elongation of the blend of chitosan and cellulose filament have also been tested. The test showes that the increasing of the fiber titer in the blend tropocollagen of the chitosan, the effect on the elongation and the tenacity is ignore. When the content of tropocollagen is up to 10 %, it displays the best elasticity. The strength and elasticity of cellulose filament decrease due to the addition of silk fibroin, but it shows the excellent mechanical property when chitin as a third component is added. Finally it indicates that there are well compatibility and promotion for mechanical property of filament between bioactive materials and chitin, chitosan and cellulose which studied by SEM.
