摘　　要：为了提高细纱成纱质量,介绍了聚氨酯弹性体材料的特点,详细对比分析了不同硬度、不同厂家聚氨酯胶辊与丁腈胶辊在不同工艺应用不同器材后的试纺对比,从套制、磨砺、表面处理和回磨周期四个方面探讨了如何对聚氨酯胶辊进行正确使用与维护。指出:聚氨酯胶辊能明显降低成纱粗节、细节和棉结,在使用中变形极小且耐用,上车基本无走熟期,能适应车间温湿度的突然变化;生产使用中,聚氨酯胶辊硬度可偏低选择,具有较长的上机使用周期,涩性较强,易粘带纤维,须加强维护管理,做好磨砺和表面处理,保持胶辊表面细腻、滑爽。To improve the spinning quality of yarn, introduction is made to the characteristics of PU elastomer material. Detailed comparative analysis is done to rollers of different hardness, different manufacturers and NBR rollers in different process using different accessories in trial spinning.Probing is done into the cautions in correct use and maintenance of PU rollers from telescoping,grinding,surface treatment and regrinding.It is pointed out that PU rollers can significantly reduce hubs,thins, and neps.The rollers are of small deformation and good durability. There is no phase-in period, adapt to sudden changes in humiture in production. It is recommended that Pu rollers can be selected in a lower degree than that as desired. However,the Pu rollers have long service cycle with strong astringent,easy stick with fiber.Something must be done to strengthen maintenance management, grinding surface treatment, keeping the roller surface smooth.
