粗纱捻系数对赛络纺亚麻/涤纶混纺纱性能的影响

Effects of roving twist factor on properties of siro spinning linen/polyester blended yarn

对亚麻/涤纶赛络纺纱试纺,研究粗纱捻系数对赛络纺纱线性能的影响。通过在23.6 tex亚麻/涤纶赛络纺纱的前纺工序中,采用不同的粗纱捻系数,可以得到不同的纱线质量,并对纱线的毛羽、强度、条干CV值等各项指标进行测试与分析。实验结果表明:随着粗纱捻系数的增加,亚麻/涤纶赛络纱的细节减少,粗节增加,但整体条干CV值趋于均匀,粗纱捻系数对其断裂强度的影响随着捻系数的增加而增大。

Siro spinning technology is used to spin linen/polyester yarn, to study effects of roving twist factor on properties of sirospun yarn. Through the 23.6 tex linen/polyester Siro yarn spinning, different choices of roving twist factor, we can get different quality of Siro yarn. Providing measurement and analysis on indexes of the yarn hairiness, strength and evenness under different roving twist factor. The experimen results show that： with the increase of roving twist factor, the details of the 23.6 tex linen/polyester Siro yarn reduced, slub on the increase, but the whole article tended to be uniform, and effects of roving twist factor on the 23.6 tex linen/polyester Siro yarn breaking strength is that yarn breaking strength is increased with the increase of roving twist factor.
