| 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.

| Abstract: | The M/G values of different sodium alginate were studied by means of 1H-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-aiginate. Gradually increasing the conceatration of coagulation bath, it increases until the concentration is up to 5%. However,it reduces with lasting coagulating time. |
