【摘要】 为了提高丝绸产品的质量,对蚕丝绸辐射接枝化学单体的原理和方法进行了更深入地研究。采用预辐射接枝方法将甲基丙烯酰胺单体接枝于蚕丝绸上,研究了接枝率与预辐射剂量、剂量率、接枝反应时间、单体浓度和样品含水量等的关系。此外,讨论了预辐射接枝反应机理;对蚕丝绸预辐射接枝法与辐射固相接枝聚合方法进行了比较,显然,预辐射接枝方法有许多优点,它可实现蚕丝纤维的表面接枝,适合于改善丝绸的染色性能,以及应用于丝绸抗静电、防污、阻燃和卫生整理中。更多还原

【Abstract】 In order to improve the properties of natural silk fabrics, the mechanism and method of the radiation induced graft copolymerization of monomers onto natural silk fabrics were more studied. Grafting of methacrylamide onto natural silk fabrics by the preirradiation grafting method have been made. The dependencies of the grafting yield on preirradiation dose, dose rates, grafting reaction time, monomers content and moisture in sample were investigated respectively. The mechanism of the preirradiation grafting was discussed. The comparison of the preirradiation grafting method with the radiation-induced solid phase graft copolymerization was made. It is evident that the preirradiation grafting method has many advantages. It can carry out surface layer graft of monomer onto natural silk fabrics. The printing and dyeing performance was improved and so on.更多还原
