GRAFTING ONTO WOOL V.RADIATION-INITIATED GRAFTING OF ACRYLIC ACID ONTO WOOL FIBER

This paper deals with graft copolymerization of acrylic acid (AA) onto Xinjiang fine wool.fiber in aqueous medium initiated by gamma rays. Graft copolymerization was carried out by themutual irradiation method in limited air. Percent grafting and percent efficiency have been deter-mined as a function of total dose, dose rate, concentration of monomer, wool weight and reactiontemperature. Graft copolymers are characterized with infrared (IR) spectroscopy, scanning elec-tron microscopy (SEM), and X--ray diffractometer. Properties of the grafts were studied, and compared with the virgin fiber.     

不同动物毛的两向凝胶电泳鉴定及其角蛋白组成分析

本文报道一种用于鉴定不同种属动物毛的方法。以二硫苏糖醇为还原剂在尿素存在下,抽提出毛纤维中可溶性角蛋白,经羧甲基化修饰后,通过两向聚丙烯酰胺凝胶电泳,结合对电泳区带和特征斑点的扫描,可对动物毛角蛋白组成作定性和半定量分析。
