摘　　要：研究不同捻系数比对纯棉7.3tex×2股线性能的影响。通过对捻系数为350和390的集聚纺单纱分别反向加捻成股线,并表征了股线在不同捻系数比下的表面形貌、断裂强力、强力不匀率、断裂伸长率和条干不匀率。结果表明,在一定范围内,随着捻系数比的增大,股线的强伸性和条干均有所改善;两种单纱捻系数的股线性能变化趋势相似,但单纱捻系数390的股线整体性能较好;捻系数比在0.3～0.5和1.2～1.5之间时,两种股线性能均较好。The effects of different twist s on the properties condensed yarn with of pure cotton 7. 3 tex ×2 ply and plied with different twist multipliers like surface topography, breaking strength, strength unevenness, breaking elongation and yarn unevenness were evaluated. The test results showed that the strength ＆ elongation and yarn evenness were improved as the increase of twist multiplier ratio within certain range. The change trend of plied with two single yarn twist multipliers were similar. However,the overall
