摘要:
为了纺得性能较好的PVA)纤维,文选用聚合度为3 500全水解(醇解度99.9%)的PVA为原料,以二甲基亚砜(DMSO)作为溶剂,以一定比例的甲醇和异丙醇混合溶液为凝固浴,采用干湿法纺丝方法制备出综合性能良好的PVA纤维。对纺得的初生纤维进行拉伸测试,比较不同PVA原液纺得纤维的断裂强度的差异。通过对初生纤维的断裂强度的测试发现,在实验范围内的最佳条件下,初生纤维断裂强度最大可达到1.1±0.04) cN/dtex。使用扫描电子显微镜对PVA纤维样品进行观测,发现采用干湿法方法纺得的PVA/DMSO初生纤维表面均光滑无沟槽。
Abstract:
In order to obtain PVA fiber with high performance, PVA fibers with good comprehensive performance was prepared with dry-wet spinning method by using PVA with degree of polymerization of 3500 and total hydrolysis (99.9% alcoholysis) as the raw material, using dimethyl sulfoxide (DMSO) as the solvent, and using the mixed solution of methanol and propanol as the coagulation bath. Tensile testing of the raw fibers was carried out to compare the differences in the breaking strength of the fibers spun from different concentrations of PVA. Through the test of the breaking strength of the raw fibers, it is found that the breaking strength of the raw fibers can reach (1.1±0.04) cN/dtex under the optimum conditions in the experimental range. The PVA fiber samples were observed by scanning electron microscopy (SEM). It is found that the surface of PVA / DMSO raw fibers is smooth and trenchless
