摘要
将同向低捻纱线运用于纯棉机织物中,在保有机织物挺刮感的同时,一定程度上提升了机织物的弹性和柔软度。采用赛络纺纺纱工艺研发同向低捻纱线及其机织物,在不改造传统赛络纺设备的前提下,通过加入长绒棉,并采用精梳工序提升低捻纱线的可纺性。通过探究3种长、细绒棉配比下的低捻单纱纺纱工艺、同向低捻合股线的倍捻工艺并进行性能测试,最终根据测试结果进一步制定织造方案,并分析面料性能。测试结果显示:当3种长绒棉配比及单纱捻系数不同时,随着股线捻度的增加,股线的拉伸断裂强力整体呈上升趋势。双轴向拉伸、压缩、弯曲测试结果显示:同向低捻纱机织物在蓬松度、柔软度、弹性、变形回复能力方面优于常规ZS纱织物,且性能随长绒棉含量的增加而上升。
Using fleeciness, softness and fullness low twist yarn in the pure cotton woven fabric can keep it scrip and improve its elasticity and softness. The low twist yarn and its woven fabric by joining long-staple cotton and combing process without transformingtraditional siro spinning machine are studied. By exploring low twist single yarn spinning process and double-twisting process of the samelow-twisted strand with three kinds of long, fine cotton ratios, synteny low twist yarn twisting process and testing the performance of theyarns, finally the weaving plan is further made according to the test results and the performance of the fabric is analyzed to study the wovenfabrics made by plied yarn. The test results show that when the three kinds of long-staple cotton ratio and single yarn twist coefficient aredifferent, the tensile strength of the strands increases with the increase of strand twist. The results of biaxial stretching, compression andbending test show that the same-direction low-twist woven fabric is superior to the conventional ZS yarn fabric in terms of bulkiness, softness,elasticity and deformation recovery ability, and the improvement is better with the increase of long-staple cotton content.
