1、紧密纺,Compact Spinning Yarn,Name：xioamingNumber：20104587,1.Profile of Compact Spinning Yarn,Compact yarn is a new kind of yarn on ring spinning machine a new spinning technology.,1.紧密纺简介 紧密纺是在改进的新型环锭细纱机上进行纺纱的一种新型纺纱技术。,2.Yarn spinning principle,The spinning mechanism is mainly:on ring spinning machine
2、of towing attachment in front adds a condensed area fiber,eliminates the front roller to twist yarn twisting triangle.,2.紧密纺的纺纱原理 其纺纱机理主要是：在环锭细纱机牵引装置前增加了一个纤维凝聚区，基本消除了前罗拉至加捻点之间的纺纱加捻三角区。,Fiber roller front output rear,first going to the special suction tube jacket mesh eyelids,eyelid ring movement in
3、the net,due to contraction of the air flow and the aggregation function,through special pipe suction shroud the agglomeration,turning gradually from the flat ribbon into a cylinder.,纤维须条从前罗拉前口输出后，先经过异形吸风管外套网眼皮圈，须条在网眼皮圈上运动，由于气流的收缩和聚合作用，通过异形管的吸风槽使须条集聚、转动，逐步从扁平带状转为圆柱体。,The head of the fiber are twisted
4、 into yarns,yarn very close,smooth yarn appearance,less hairy.Compact spinning high strength,less Hairiness.Most easily sanded in the weaving process.,纤维的端头均捻入纱线内，因此成纱非常紧密，纱线外观光洁、毛羽少。紧密纺纱线 强力较高，毛羽较少。在编织过程中最不易产生磨毛的现象。,Compact spinning yarn twisting is the purpose of the former parallel and as close a
5、s possible between the fiber,high quality compact yarn is an important criterion.The fiber is parallel and consistent as possible before twisting its advantage on the assumption.,紧密纺的目的是在纱线加捻前使纤维之间尽可能平行并接近，对于高质量的紧密纺纱线这是重要的评判标准。使纤维尽可能平行并保持一致在加捻前是其优势的前提。,3.Advantages of compact spinning,（1）Due to twis
6、ting fibers fully outstretched,parallel,no feathers out of gauze,so spinning Hairiness rarely,especially more than 3 mm less Hairiness.,3.紧密纺的优点（1）由于加捻前单纤维充分伸直、平行，没有毛羽伸出纱条主体，所以成纱毛羽很少，特别是3毫米以上毛羽极少。,（2）Because every single fibers in the spinning is twisting under straight and parallel,at the time of s
7、ingle yarn tensile,basically the same single fibers mechanical,compact spinning higher strength than the traditional single yarn.,（2）在细纱中由于各单纤维是在伸直、平行的状态下加捻，在单纱受到拉力时，各单纤维受力基本一致，所以紧密纺强力比传统单纱高。而且由于紧密纱中的单纤维排列紧密，相互间抱合力大，这也有助于提高纱线的强力。,（2）Compact spinning process,the yarn is done in the process gathered a
8、fter the drafting of the provisions,so its unevenness,indicators have not improved,and twisting roller clamp while twisting fiber inner and outer shifted strongly without the traditional craftsmanship,so compact yarn unevenness,rough and detailed indicators is better than traditional yarn.,（2）在紧密纺工艺
9、中，纱条是在完成了工艺规定的牵伸之后再进行聚集，所以其条干不匀的指标没有大的改善，且在加捻罗拉钳口处加捻时纤维的内、外层转移没有传统工艺强烈，所以紧密纱的条干不匀，粗、细节指标比传统纱要好。,（3）Compact yarn less hairy,so ease pressure on operations such as sizing,Singeing,shuttleless loom weft greatly reduced when using compact yarn,weft resistance to improve loom efficiency.,（3）紧密纱毛羽少，所以减轻了上
10、浆、烧毛等工序的压力，在无梭织机的纬纱使用紧密纱时大大减少了引纬的阻力，提高了织机效率。,4.Shortcomings of compact spinning,（1）Higher cost of compact spinning equipments,increases the investment in equipment of spinning mills.,4.紧密纺的缺点（1）紧密纺设备的造价较高，增加了纺纱厂的设备投资。,（2）Indicators in addition to Hairiness has a lot of room for improvement,yarn of other indicators such as dry,rough and detail improvements at a modest rate.,（2）除了毛羽指标有很大的改善之处，纱线的其它指标如条干、粗、细节等改善幅度不大。,THE END,THANK YOU!,
