摘　　要：为综合反映加捻作用对股线性能的影响,分别采用捻系数为320、340、360的纯棉粗纱进行单纱纺制。采用两根或三根相同的单纱进行反向加捻成双股线或三股线,探究单纱捻系数与合股时捻系数比对相应股线强伸性、条干的影响。研究结果表明:单纱捻系数为360、捻系数比为1.4时,两股线各项性能最好,与捻系数比为0.6的两股线相比,强力提高56.8%,条干均匀度提高18.6%,毛羽H值降低34.1%;单纱捻系数为360、捻系数比为1.7时,三股线各项性能最好,与捻系数比为0.5的三股线相比,强力提高36.4%,条干均匀度提高62.5%,毛羽H值降低28.3%。In order to comprehensively reflect the effect of twisting on the linear performance of the strand,pure cotton roving is selected as raw material,and single yarn is spun with twist factors of 320,340 and 360 respectively.Two or three identical single yarns are used to re⁃versely twist into double strands or three strands,and the influence of the twist factor ratio of single yarn to ply on the strength,elongation and evenness of the corresponding strands isinvestigated.The results show that when the twist factor of the single yarn is 360 and the twist fac⁃tor ratio is 1.4,the performance of the two-strand yarn is the best.Compared with the two-strand yarn with a twist factor ratio of 0.6,the strength is increased by 56.8%,the evenness is increased by 18.6%,and the hairiness H value is reduced by 34.1%.When the twist factor of the single yarn is 360 and the twist factor ratio is 1.7,the performance of the triple yarn is the best.Compared with the triple yarn with a twist factor ratio of 0.5,the strength is increased by 36.4%,the evenness is increased by 62.5%,and the hairiness H value is reduced by 28.3%.
