【摘要】 真丝纤维面料有着穿着舒适,光泽柔和,手感优良等优良的性能,长期以来一直受到人们的青睐,是一种高档华贵的纺织材料。但是它也有很多缺陷,如易泛黄、易起绒、湿弹差等,因而真丝的改性整理研究工作具有非常重大的现实意义。本文针对真丝的结构性能特点,在参考了国内外大量接枝改性真丝方法的基础上,采用化学引发、等离子体引发和辐照引发等方法接枝共聚改性真丝。采用具有抗菌效能的阳离子季铵盐单体化合物甲基丙烯酰氧乙基三甲基氯化铵作为改性整理剂,改变接枝反应条件,如单体浓度、引发剂浓度、整理浴pH 值、整理浴温度及接枝时间等,研究了在阳离子单体化合物与真丝的接枝反应中影响接枝增重率的因素。在考虑了各种反应因素影响的基础上,得到较佳的接枝条件,优化了接枝工艺。本研究还测试了接枝真丝的白度、回潮率、力学性能等;另外,采用红外光谱(IR )、X-ray 衍射分析、热分析、氨基酸分析和扫描电镜等现代测试手段对接枝改性后的真丝的结构进行了分析,探讨了接枝改性后真丝大致的结构变化。本研究结果表明,本单体能够对真丝进行接枝改性,接枝增重率的大小可以通过改变工艺条件来控制;改性真丝的性能有很大改善,抗菌效果明显。本研究的结果,对拓展真丝的改性研究和实际生产具有一定的现实意义。更多还原

【Abstract】 In this paper, for the purpose of improving the silk properties, graft copolymerization of cationic compound on silk fiber was studied according to silk fiber structure characters. Two initiators, Ammonium Cerium(Ⅳ) nitrate(CAN) and Potassium Persul phate(KPS), and two kinds of initiation methods, plasma treatment and radiation treatment, were used to initiate graft copolymerization between cationic compound and silk. And other influences of initiator concentration, radiation dose, compound concentration, pH value, temperature and reaction time of graft copomerization were shown and optimized method can be derived from the experiment results. The physical properties of ungrafted and grafted silk fiber were tested to find the changes of grafted silk fiber. And other analysis methods like infrared spectroscopy(IR), scanning electron micrograph photographs(SEM), wide-angle X-ray diffraction patterns(WAXD), thermogravimetric analysis(TGA) 、differential scanning colorimetry(DSC) and amino acid analysis were done to study the graft copolymerization and verify reaction mechanism. In the end, good antibacterial effect was shown by experiment.更多还原
