摘要
The M/G values of different sodium alginate were studied by means of H-NMR. The alginate fiber was prepared via wet-spinning technology. The effects of M/G, the concentration of sodium-alginate, the concentration of the coagulation bath and coagulating time on the absorptive ability of alginate fiber were discussed. The results show that the absorptive ability to different substances varies in such order： physiological saline 〉 blood 〉 tap water 〉distilled water. The absorptive ability of the alginate fiber increases with the increase of M/G value and the concentration of sodium-alginate. Gradually increasing the concntration of coagulation bath, it increases until the concentration is up to 5%. However, it reduces with lasting coagulating tine.
不同的钠 alginate 的 M/G 价值借助于 1H-NMR 被学习。alginate 纤维经由湿旋转的技术被准备。M/G， sodium-alginate 的集中，凝结洗澡的集中和 alginate 纤维的吸收性的能力上的凝结的时间的效果被讨论。结果证明不同物质的吸收性的能力在如此的顺序变化：生理盐 > 血 > 自来水 > 提取的水。alginate 纤维的吸收性的能力随 M/G 价值的增加和 sodium-aiginate 的集中增加。逐渐地增加凝结洗澡的 conceatration，它增加直到集中直到 5% 。然而，它与持续减少使时间凝结。
