摘　　要：为显著降低环锭纱线毛羽,采用环锭给液纺进行纺纱,利用特定溶液与纤维之间的相互作用加强纤维控制,使毛羽紧密贴服在须条表面,并在加捻过程中被卷入须条内部,完成有害毛羽的有效降低。选取与纤维素极性相似的聚丙烯酸钠(PAAS)配置不同浓度溶液,对溶液性能与所纺纱线的结构与性能进行测试,结果表明,随PAAS浓度的增加,溶液表面张力逐渐增加并接近水的表面张力,粘度提高,对应粗纱粘附力也相应增加。给液纺纱线表面更加紧密光洁,纱线毛羽大幅度减少,毛羽减少率达60%以上,络筒后仍可保持,纱线强力与耐磨性能也有一定提升。因此,采用PAAS溶液进行给液纺纱生产纯棉纱线确实可有效降低纱线毛羽,改善纱线强力与耐磨性能,综合提升纱线品质。In order to reduce the hairiness of adhesive-aided ring spun yarn significantly,the adhesive-aided ring spinning is used to produce yarn in this article.The interaction between specific solution and fiber is used to strengthen the fiber control,so that the hairiness is closely contacted to the yarn surface,then the hairiness is involved into the interior of the fiber strand during the twisting process,and the harmful hairiness is effectively reduced.Therefore,sodium polyacrylate(PAAS)with similar polarity to cellulose was selected to prepare different concentrations of solutions,and the properties of the solution and the structure and properties of the spun yarns were tested.The results shows that the surface tension of the solution increases gradually and approaches the surface tension of water with the increase of PAAS concentration,and the viscosity of PAAS solution and the roving adhesion also increase.The surface of the adhesive-aided ring spun yarn is more compact and smooth.The yarn hairiness is greatly reduced and the hairiness reduction rate of bobbin yarn is more than 60%,and the similar hairiness reduction rate of cone yarn is still maintained after winding.The yarn strength and resistance performance of adhesives-aided ring spun yarns are also improved.Therefore,the adhesive-aided ring spinning can effectively reduce yarn hairiness,improve yarn strength and resistance performance,and improve yarn quality comprehensively.
