用湿法纺丝制备琼胶纤维,扫描电镜(SEM)观察纤维的表面形态,并且测试了纤维的拉伸性能和吸水性能。结果表明用二甲基亚砜(DMSO)做溶剂,50%无水乙醇做凝固浴,纺丝原液的溶度为12%,可制得纤维性能良好的琼胶纤维,而且纤维的拉伸强度达到了5.52 cN/tex,在蒸馏水中的膨胀度为114%,在0.9%的盐溶液中为111%。 Agarose fibers were prepared by wet spinning, the surface morphology of the fibers was observed by scanning electron microscopy (SEM), and the tensile properties and water absorption properties of the fibers were tested. The results show that with dimethyl sulfoxide (DMSO) as a solvent, 50% absolute ethanol coagulation bath, the spinning solution of the solubility of 12%, can be prepared good agar fiber properties, and the fiber tensile strength Reached 5.52 cN / tex, swelling in distilled water was 114% and 111% in 0.9% salt solution.
