6、 into a cylinder.纤维须条从前罗拉前口输出后，先经过异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。平带状转为圆柱体。The head of the fiber are twisted into The head of the fiber are twisted into yarns,yarn very close,smooth yarn yar
7、ns,yarn very close,smooth yarn appearance,less hairy.Compact spinning appearance,less hairy.Compact spinning high strength,less Hairiness.Most high strength,less Hairiness.Most easily sanded in the weaving process.easily sanded in the weaving process.纤维的端头均捻入纱线内，因此成纱非常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
8、。紧密纺纱线紧密，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强力较高，毛羽较少。在编织过程中最不易产生磨毛的现象。产生磨毛的现象。Compact spinning yarn twisting is the Compact spinning yarn twisting is the purpose of the former parallel and as purpose of the former parallel and as close as possible between the fiber,high close as possible between t
9、he fiber,high quality compact yarn is an important quality compact yarn is an important criterion.The fiber is parallel and criterion.The fiber is parallel and consistent as possible before twisting consistent as possible before twisting its advantage on the assumption.its advantage on the assumptio
10、n.紧密纺的目的是在纱线加捻前使纤维之间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。并保持一致在加捻前是其优势的前提。3.Advantages of compact spinning3.Advantages of compact spinning（1 1）Due to twisting fibers fully Due to twisting fibers fully outstretched,parallel,no
11、feathers out outstretched,parallel,no feathers out of gauze,so spinning Hairiness rarely,of gauze,so spinning Hairiness rarely,especially more than 3 mm less Hairiness.especially more than 3 mm less Hairiness.3.紧密纺的优点紧密纺的优点（1）由于加捻前单纤维充分伸直、平行，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，没有毛羽伸出纱条主体，所以成纱毛羽很少，特别
12、是特别是3毫米以上毛羽极少。毫米以上毛羽极少。（2 2）Because every single fibers in the Because every single fibers in the spinning is twisting under straight and spinning is twisting under straight and parallel,at the time of single yarn parallel,at the time of single yarn tensile,basically the same single tensile,basicall
13、y the same single fibers mechanical,compact spinning fibers mechanical,compact spinning higher strength than the traditional higher strength than the traditional single yarn.single yarn.（2）在细纱中由于各单纤维是在伸直、平行的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。而且基本一致，所以紧密纺强力
14、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。大，这也有助于提高纱线的强力。（2 2）Compact spinning process,the yarn is Compact spinning process,the yarn is done in the process gathered after the done in the process gathered after the drafting of the provisions,so its unevenness,drafting of the p
15、rovisions,so its unevenness,indicators have not improved,and twisting indicators have not improved,and twisting roller clamp while twisting fiber inner and roller clamp while twisting fiber inner and outer shifted strongly without the traditional outer shifted strongly without the traditional crafts
16、manship,so compact yarn unevenness,craftsmanship,so compact yarn unevenness,rough and detailed indicators is better than rough and detailed indicators is better than traditional yarn.traditional yarn.（2 2）在紧密纺工艺中，纱条是在完成了工艺规定的牵在紧密纺工艺中，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
17、捻罗拉钳口处加捻时纤维的内、外层转移没善，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。标比传统纱要好。（3 3）Compact yarn less hairy,so ease pressure Compact yarn less hairy,so ease pressure on operations such as sizing,Singeing,on operations such as sizing,Singeing,shuttleless loom weft greatly
18、reduced when shuttleless loom weft greatly reduced when using compact yarn,weft resistance to improve using compact yarn,weft resistance to improve loom efficiency.loom efficiency.（3 3）紧密纱毛羽少，所以减轻了上浆、烧毛等工序的紧密纱毛羽少，所以减轻了上浆、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。的阻力，提高了织机效率。4
19、.Shortcomings of compact spinning4.Shortcomings of compact spinning（1 1）Higher cost of compact spinning Higher cost of compact spinning equipments,increases the investment in equipments,increases the investment in equipment of spinning mills.equipment of spinning mills.4.紧密纺的缺点紧密纺的缺点（1）紧密纺设备的造价较高，增加
20、了纺纱紧密纺设备的造价较高，增加了纺纱厂的设备投资。厂的设备投资。（2 2）Indicators in addition to Hairiness has a Indicators in addition to Hairiness has a lot of room for improvement,yarn of other lot of room for improvement,yarn of other indicators such as dry,rough and detail indicators such as dry,rough and detail improvements at a modest rate.improvements at a modest rate.（2 2）除了毛羽指标有很大的改善之处，纱线的其它指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。标如条干、粗、细节等改善幅度不大。
