探讨混纺比对Modal纤维棉混纺纱性能的影响.选取Modal纤维与棉为原料,分别纺制14.5 tex的纯棉精梳纱、纯Modal纱以及Modal与棉混纺比分别为20/80、30/70、40/60、50/50的混纺精梳纱,并通过对比试验,分析了混纺比对成纱强伸性能、条干、毛羽的影响.结果表明:从提高混纺纱断裂强度考虑,混纺比选择50/50比较适宜;Modal纤维的含量在40％左右时,成纱条干较好；混纺比为40/60或50/50左右时,成纱毛羽数较低.%Effect of blending ratio on Modal fiber cotton blended yarn quality was discussed. Modal fiber and cotton were selected as raw material,pure cotton 14. 5 tex combed yarn was spun,pure Modal 14. 5 tex yarn was spun,Modal cotton blended yarns were spun as well,the blending ratio was 20/80,30/70,40/60 and 50/50- Through contrast and test,effect of blending ratio on yarn strength and elongation,evenness and hairiness were analyzed. The result shows when adopting the blending ratio of 50/50 breaking intensity of the blended yarn is better,when adopt the blending ratio of 40/60 evenness of the blended yarn is better, when adopt the blending ratio of 50/50 or 40/60 hairiness of the blended yarns are better.
