紧密赛络纺集聚效果及纱线结构分析

紧密赛络纺将紧密纺与赛络纺技术相结合,所纺纱线具有紧密纱与合股纱的优点,毛羽少,强力高,结构紧密,摩擦性能好,介绍了紧密赛络纺纱技术的原理及特点。用自行研制的具有不同吸风双槽的紧密赛络纺吸风管分别纺制相同线密度的棉纱,并与相同工艺条件下的紧密纺和赛络纺纱线就纱线结构与性能进行比较分析,进一步说明紧密赛络纺纱工艺的优越性。同时,用模糊数学的方法对结构不同的吸风双槽进行综合性能评判,选出所纺纱线综合性能最佳的紧密赛络纺吸风装置。

Analysis of compact effect and yarn structure of compact Siro spinning

Combing the advantages of the compact spinning with Silo spinning, compact sirospun yam possesses good performances of both the compact yam and two-ply yam, such as high strength, less hairy, compact structure and high abrasion resistance. The principle and features of the compact Siro spinning technology are introduced in this paper. Several profile suction pipes with different double slots are developed and applied to spin cotton yams of same fineness. Though comparing the structure and performance of this cotton yam with that of yarns by the compact spinning or the Silo spinning, the advantages of compact Siro spinning are further indicated. Finally, the results of these suction slots are evaluated by fuzzy mathematics, and the suction installation by which yams with the best comprehensive performances are spun is selected.
