摘要: 为了提高棉纺环锭细纱的成纱质量,提出并介绍了假捻集聚纺纱方法,并通过纺纱实验研究了采用此种纺纱方法时假捻器转速比、转向以及牵伸形式对纱线条干CV值、毛羽指数、断裂强度和断裂伸长率四项性能的影响。实验结果表明皮圈牵伸系统所纺纱线质量要好于简单罗拉牵伸系统。假捻器的转向选择要根据粗纱的捻向而确定,如果粗纱为“Z”捻,则假捻器应为逆时针转动。假捻器转速比的作用受到其它纺纱参数的影响,当假捻器呈逆时针转动时,最佳转速比约为0.36;而当假捻器呈顺时针转动时,纱线的各项性能随着转速比的增大而有所提高。

Abstract: The false-twist compact spinning method was suggested to improve the quality of cotton ring spinning yarn. A series of spinning experiments were conducted to investigate the influences of drafting systems, rotational speed ratio and rotational direction of the false twister on yarn evenness, hairiness index, breaking strength and breaking elongation. The results showed that the yarns produced on the double-apron drafting system have better qualities than that produced on the simple three-roller drafting system. The rotational direction should be adjusted according to the twist direction of the roving. The twist direction of the roving used in the experiment is “Z” twist, so the rotational direction should be counterclockwise. The experiment results also indicated the determination of rotational speed ratio should be based on other spinning parameters. When the rotational direction of the false twister is counterclockwise, the optimum rotational speed ratio is 0.36. When the false twister runs clockwise, the rotational speed ratio should be higher to improve yarn quality.

Key words: Cotton ring spinning, False-twist Compact spinning, False twister, Rotational speed ratio, Drafting system, Yarn property
