海藻酸钡纤维的制备和性能研究

Preparation and properties of barium alginate fiber

以海藻酸钠为原料,0.5mol/L氯化钡水溶液为凝固浴,通过湿法纺丝制备了海藻酸钡纤维。利用扫描电镜、红外光谱仪对制得的纤维进行了表征,并对纤维进行了单纤维拉伸测试和防辐射性能测试。研究表明,海藻酸钠在凝胶化过程中形成明显的螯合结构,海藻酸钡纤维的平均断裂强度20.69cN/tex,线密度为3.86dtex,与普通粘胶纤维相比海藻酸钡纤维有明显的防辐射性能。

Barium alginate fibers were prepared through wet-spinning of alginate sodium into coagulationg bath containing 0.5mol/L barium chloride. The composition and morphology of barium alginate fibers were investigated with FT-IR and SEM. The mechnical property and anti-radiation property of barium algiante were analysized. It revealed that the average tensile strength of the barium algiante fiber was 20.69cN/tex and the line density was 3.86dtex. Barium alginate fiber has good anti-radiation property compared with viscose fibers.
