摘　　要：纱线的强伸性能与捻系数有着直接关系,了解临界捻系数的分布对合理选用捻系数至关重要。对CJ18.2 tex和CJ14.6 tex两种纱线在不同设计捻系数下的强伸性进行研究。结果表明:所纺CJ 18.2 tex纱的临界捻系数约为500,CJ14.6 tex纱的临界捻系数约为460,且在各自临界捻系数附近强力达到最大值。Yarn strength and elongation have direct relationship with the twist factor. The critical twist faclor distribution is of great importance in selecting twist factor. In this paper, the strength and elongation of CJ18.2tex yarn and CJ14.6tex yarn spun with different twist factors were studied. The result shows that the critical twist factor of CJ18.2tex yarn is 500 appropriately and the critical twist factor of CJ14.6tex yarn is 460 appropriately. They own their best strength when spun by using critical twist factors.
