摘　　要：实验研究了添加不同质量分数的硼酸凝胶剂对以聚乙烯醇(PVA)为载体,制备干质量比为1∶6的PVA/聚四氟乙烯(PTFE)纤维的纺丝工艺工艺参数和复合初生纤维质量的影响;实验还探讨了将硼酸作为外部凝固浴纺制PVA/PTFE纤维的可行性。结果表明:凝胶剂质量分数多的浆液在其本身最佳的纺制参数条件下纺制出的PVA/PTFE复合纤维的强度较佳;将硼酸作为外部凝固浴纺制具有一定的可行性。The influence of concentration of boric acid on fabrication parameters and the properties of PVA/ PTFE（net weight ratio 1∶6） fiber was studied in the article.The possibility of using boric acid as coagulation bath was also studied.The results showed that the mechanical properties of PVA/ PTFE Fiber were improved with increasing of concentration of boric acid.The possibility of using boric acid as coagulation bath was proven,but the suitable concentration should be tested further.
