丝胶蛋白处理氧化亚麻纤维的工艺研究

The Processing Parameter Analysis of Oxidized Flax Fiber Treated with Sericin Solution

采用高碘酸钠对亚麻纤维进行选择性氧化生成醛基,再利用丝胶蛋白溶液对氧化亚麻纤维进行改性接枝加工,研究了不同处理条件对丝胶处理氧化亚麻纱线的增重率、断裂强度和断裂伸长率的影响。结果表明,不同处理条件对氧化亚麻纤维的增重率有一定的影响,但氧化亚麻纤维经丝胶蛋白溶液处理后的断裂强度和断裂伸长率基本不变。

The flax fiber was oxidized by sodium periodate to cleave the 2.3-vicinal diol of the cellulose glucose units, giving the flax fiber with two aldehyde groups. Subsequently, the oxidized flax fiber was treated with sericin solution. Factors which may affect the weight gain, the breaking strength and the breaking elongation of the oxidized flax fiber treated with sericin solution were discussed. The results show that the weight gain of the oxidized flax fiber was affected by the concentration of sericin solution, pH value, treated time and treated temperature. However, little change was found on the breaking strength and the breaking elongation of the oxidized flax fiber treated with sericin solution.
