摘　　要：为了研究涤纶长丝与涤棉短纤纱并捻复合纱线的力学性能。分析了并捻张力、并捻捻度和复捻捻向对复合纱线强伸性能和外观的影响情况。结果表明 ,不同的并捻张力配置对复合纱线强力和外观影响较大 ;复合纱线存在临界捻度 ;采用同向加捻和适当捻度 ,复合纱线外观和力学性能良好。To study the mechanical properties of polyester filament and blended yarn of polyester & cotton, the effect of tension, twist and after twist direction of doubling & twisting on the strength, elongation and appearance of composite yarn are analyzed. The results show that tension configurations of doubling & twisting much affect the strength and appearance of the composite yarn. There is a critical twist of the composite yarn. The appearance and mechanical properties of the composite yarn are good with twist on twist and a correct twist selection.
