摘　　要：以聚乙烯醇(PVAL)和卡拉胶为原料配制纺丝液,通过湿法纺丝技术制备不同种类的复合纤维。通过扫描电子显微镜、单纤维测试仪、极限氧指数(LOI)仪、锥形量热仪、热重分析仪等对纤维的形貌特征、力学性能和阻燃性能进行测试。结果表明,采用AlCl3溶液为凝固浴,以95%乙醇为拉伸浴制备的复合纤维(PVAL/CAF–Al)形貌良好,力学性能优良,断裂强度达到1.85 cN/dtex,并且其阻燃性能优良,LOI值高达36%,在800℃下燃烧2 h仍能够保持良好的纤维形态。Different kinds of composite fibers were prepared by wet spinning with polyvinyl alcohol(PVAL)and carrageenan as raw materials.The morphology,mechanical properties and flame retardant properties of the fibers were tested by scanning elec-tron microscope,single fiber tester,limited oxygen index(LOI)meter,cone calorimeter and thermogravimetric analyzer.The re-sults show that the composite fiber(PVAL/CAF–Al)prepared with AlCl3 solution as coagulation bath and 95%ethanol as stretching bath has good morphology,excellent mechanical properties with breaking strength reaches 1.85 cN/dtex.LOI value of PVAL/CAF–Al is 36%,and it can keep good fiber morphology after burning for two hours at 800℃.
