【摘要】 研究棉纤维经丝胶处理后的聚集态结构。采用高碘酸钠对棉纤维进行选择性氧化,再利用丝胶溶液对棉纤维进行处理,使丝胶涂覆于棉纤维上,通过FT-IR、XRD和DSC等方法对处理后棉纤维的结构进行了测试分析。结果表明,丝胶蛋白分子与氧化棉纤维之间形成了共价结合键;氧化棉纤维经丝胶蛋白溶液处理后结晶度无明显变化,其热稳定性有所提高。更多还原

【Abstract】 Aggregating structural analyses of cotton fibre treated by sericin were studied.Cotton fibre was selectively oxidized with NaIO4 and treated by sericin solution that covered cotton fibre.The structure of treated cotton fiber were analysed by means of FT-IR,XRD and DSC.The result shows that sericin proteinic molecule is linked by oxidized cotton fiber through covalent bond.After treating by sericin solution the crystallinity is not changed significantly while the thermal stability of the oxidized cotton fibre improved in a degree.更多还原
