摘　　要：在高速经编机上编链,分别采用11.6、9.7、7.3 tex的紧密纺棉纱完成送经、垫纱、成圈等加工过程,通过改变上机编织的组织结构,分别从经编机的盘头、分纱筘、导纱针和成圈部位取样,测试纱线捻度和毛羽,对纱线棉结微观形貌进行分析研究。试验测试表明:当成圈运动方向与纱线捻度一致时,捻度增大,反之,捻度减小,且捻度越大变化越明显。同种棉纱不同组织结构,横移针数越大,张力越大,棉纱受摩擦影响越小,毛羽增加和减少的幅度越小;成圈部位是捻度和毛羽数量变化的主要影响因素,同时也是棉结形成的主要位置。On a high-speed warp knitting machine,compact spun cotton yarns of 11.6,9.7 and 7.6 tex are used for knitting with warp feeding,padding,and looping.By changing the knitting texture,samples are taken from the disc head,dividing reed,guide needle,and looping parts of the warp knitting machine to test the yarn twist and hairiness,and to analyze and study the microstructure of the yarn neps.Experimental tests show that when the direction of the loop motion is consistent with the twist of the yarn,the twist increases.Conversely,the twist decreases,and the greater the twist,the more significant the change.For the same type of cotton yarn with different texture,the larger the number of lateral needles and the greater the tension,the less affected on cotton yarn by friction,and the smaller the magnitude of increase and decrease in hairiness;The looping position is the main influencing factor for changes in twist and hairiness,and it is also the main location for the formation of cotton neps.
