摘　　要：将芳砜纶纤维分别与高强涤纶纤维、阻燃粘胶纤维按照不同比例混纺,测试混纺纱的强伸性能、外观质量和阻燃性。结果表明:芳砜纶/高强涤纶混纺纱中芳砜纶强力的临界混纺比为92.3%。随着高强涤纶比例的增加,混纺纱的断裂强力增加,断裂伸长率降低,条干不匀率及毛羽指数减少,阻燃性能下降且出现熔融现象。芳砜纶/阻燃粘胶混纺纱中阻燃粘胶强力的临界混纺比为73.8%。随着阻燃粘胶比例的增加,混纺纱的断裂强力及断裂伸长率降低,条干和毛羽有所改善,阻燃性能下降。Polysuifonamide/high tenacity polyester and polysulfonamide/fire-retardant viscose blended yarns were produced and the properties of the yarns were tested. It could be found that the critical blending ratio of polysulfonamide/high tenacity polyester was 92. 30%. The increase of high tenaci- ty polyester fibre would result in the enhancing of the yarn strength, decrease of the yarn elongation and improvement of the yarn evenness and hairi- ness as well as the reduction of the fabric flammability with melting phenomenon. The critical blending ratio of polysulfonamide/fire-retardant viscose blended yarn was 73. 8%. The increase of fire-retardant viscose fibre could cause the reduction of yarn strength and elongation and the improvement of the yarn evenness and hairiness as well as the decline of the fabric flammability.
