| 摘 要： | 通过卡拉胶与环氧氯丙烷交联反应制得改性卡拉胶;并将改性卡拉胶溶于热水制得纺丝液,采用湿法纺丝制备高强度卡拉胶纤维。红外光谱测试及粘度提高证明交联反应的发生;用单因素实验法找到影响因素的最佳范围,通过正交实验法得到最佳合成条件为温度90℃、交联剂加入量为6.25%、反应时间2.0h、pH值为10.0;利用万能材料试验机测得纯卡拉胶纤维的断裂强度为2.17cN/tex,改性卡拉胶纤维的最大断裂强度为3.99cN/tex,交联后断裂强度提高85%。

| Abstract: | Modified carrageenan was prepared by carrageenan cross-linked with epoxy chloropropane.Then the modified carrageenan went through wet-spinning frame to get the high strength carrageenan fibers.The composition of carrageenan and modified fibers were characterized by FT-IR.The viscosity was investigated by viscometer.The range of influencing factors was investigated by experiments of single factor.The optimum synthesis condition of the crosslinking was obtained by orthogonal experiments.The results showed tha... |
