【摘要】 Tencel是再生纤维素纤维,取白天然木材,其生产过程清洁无毒,99.5%以上的溶剂可被回收,极少数的残留沉淀物可在适当的生物处理过程中被降解,因此它具有良好的环保性能。 Tencel纤维非常坚韧,无论在干或湿的状态下,都具有很高的强力。在干态时,高强力意味着面料保形性好,可提高纺纱及织造的生产效率;在湿态时,高强力可以保证加工或水沈过程中织物的尺寸稳定性。其良好的吸湿性使其具有很好的着色效果,可为染厂降低生产成本。其良好的可纺性,能和棉、麻、毛、绢丝、羊绒、涤纶等各种纤维进行混纺,制成不同规格的纱支,所织成的织物穿着舒适,柔软透气,悬垂性好,皮肤触感良好,易于打理,是服装面料及家用纺织品特别是睡衣和床上用品的首选。因此我公司很重视Tencel纤维系列品种的开发和生产。 本文通过Tencel纺纱生产实践,在清、梳、并、粗、细及后加工各工序进行合理的工艺设置,结合生产流程的质量控制使其质量达到较好水平。同时在粗纱工序进行正交设计优选出最优工艺参数,进而更好的保证成纱质量。另外,对纺纱过程中出现的疵品进行波谱分析,找出故障原因,为长期有效地质量控制积累了一定经验。 为进一步提高Tencel成纱质量,引入赛络纺纱新技术。赛络纺是集纺纱、并线、捻线为一体的纺纱新技术。赛络纱及其织物风格独特,深受市场欢迎;因其设备改造费用低,产品附加值高而倍受纺织企业的青睐。本文介绍了赛络纺的工作原理、技术要求、生产设备和产品特性,及赛络纺在国产棉纺细纱机上的改造使用,通过Tencel系列品种环锭纺和赛络纺成纱指标对比,显示了赛络纱良好的性能。尤其用赛络纺技术纺氨纶包芯纱,可使包覆效果更好,纱线手感柔软,耐磨性较好,纱线条干均匀度,强伸性均优于传统的包芯纱。 作为一种新工艺,通过在传统细纱机上进行改造纺制,不仅改善成纱内外在质量,进一步适用于高速织机的需求,还可降低成本,提高产品附加值,因而具有良好的市场发展前景。更多还原

【Abstract】 Tencel is a regenerated cellulose fibre that made from natural woods.Its process of production is clean and nonpoisonous. 99.5 percent of solvent can be retrieved, very little of the left sediment can be cut down and decomposed through the suitable biological degradative process. So it has good environmental protective property.Tencel is a high-tenacity fibre. Whenever it in dry or wet condition, it has high strength. In dry condition, high strength means the fabric has good shape relenlion, it can improve spinning and weaving production efficiency. In wet condition, high strength can keep fabric’s shape stableness in production or in cleaning process. Its good hygroscopicity make it has fine substantivity, thus it can reduce the production costs in printing and dyeing mill. Tencel has good spinnability, it can blend spinning with cotton, linen, wool, silk, cachmire, polyester etc variousnt fibres, and spin various different counts of yarn. Tencel fabric is wear-comfort, softness, good breathability, great touch, and easy wash and wear. It is the first selection of wearing apparel and home textiles especially pajamas and bed clothes. So our company pay more attentions to produce and develop series new varieties.Through Tencel spinning production practice in scotching, carding, drawing, roving, spinning and winding process, we set up rational spinning process to control quality, further improve semi-manufactured goods and yarn property to good level. After all we select optimun process parameter through orthogonal design in roving to further control yarn property. On the other hand, we combine the substand and products in the process, through wavegram analysis to find reasons of the failure, finally we accumulate some experience by the effective quality control.We draw into a new spinning technology-Sirospun for further improve Tencel yarn quality. The Sirospun is a new technology of woolen spinning, which combine spinning, doubling and twisting into one operation. The Sirospun yarns and its products have special styles, good markets and high economical benefits, so the Sirospun has been well favored by textile factories because its low expenses in equipmentmodification and high extra-value of the products. The Sirospun principle, technological requirements, peocessing equipment, product specialties and processing program are described here in detail. It has important practical significance in spreading Sirospun technology in china-made spinners, and compare sirospun yarn property to ring spinning yarn property, showing sirospun yarn has very good property. Especially the Sirospun technology has been applied to produce core yarn. It can make yarn has good wraping effection, yarn touch softness, good wear-resisting, good yarn evenness, and strength is better than traditional core yarn.As a new process, through spinning in the transformed traditional ring spinning, it not only improves yarn quality but also fits to the demands of high speed of air-jet loom in the next process, and can reduce production costs, improve production additional value, so it has dood market progress prospect.更多还原
