利用湿法纺丝方法制备了海藻酸纤维。通过讨论纺丝过程中纺丝液制备、纺丝液浓度、过滤、脱泡、喷丝口、凝固浴浓度及温度、初生纤维的牵伸等诸因素的要求和对纤维的影响,得到了海藻酸纤维的纺丝最佳工艺条件。并介绍了海藻酸纤维的纺丝设备和在医用材料上的应用。
Alginate fiber is prepared by wet spinning method. The preparation process of alginate fiber is: dissolution, filtration, deaeration, figuration, stretching, washing, drying and convoluting. At present, one of the biodegradable fibers studied the most is alginate fiber. The material, principle and producing technology of alginate fibers are introduced in this article and its application in wound dressings are underlined.
