YY-J68型无差异化纺纱牵伸胶辊的研制与应用

Development and Application of YY-J68 Undifferentiated Spinning Drafting Cots

为了满足小批量、多品种纺纱对胶辊的高要求,从主体材料、补强剂、抗老化和耐疲劳结构剂3方面阐述YY-J68型无差异化纺纱牵伸胶辊的研制要点,通过抗拉试验以及与其他胶辊纺莫代尔11.66 tex纱和9.72 tex纱、LC 14.58 tex纱、C/T 55/4513.06 tex纱的成纱质量,对比分析YY-J68型胶辊性能优势,介绍其套制、磨砺与表面处理、使用与维护保养的注意事项。指出:YY-J68型胶辊适纺纯棉、混纺(涤/棉)纱,具有优良的弹性、抗拉性及抗缠绕性能,上车损坏率低、使用寿命长;选用YY-J68型胶辊纺纱,成纱的CV值、线密度平均差不匀率、细节、粗节、棉结指标均得到明显改善。

In order to meet the high requirements of cots for small batch and multi-variety spinning,the key points of development of YY-J68 undifferentiated spinning drafting cots are described from three aspects of main material,reinforcing agent,anti-aging and anti-fatigue structural agent.The performance advantages of YY-J68 cots are analyzed by anti-pull test and yarn quality comparison with other cots spinning modal 11.66 tex yarn and 9.72 tex yarn,LC 14.58 tex yarn and C/T 55/4513.06 tex yarn,and matters need attention of the setting,grinding and surface treatment,use and maintenance are introduced.It is pointed out that YY-J68 cots are suitable for spinning pure cotton and blended(polyester/cotton)yarns,with excellent elasticity,anti-pull and winding resistance,low damage rate and long service life.When YY-J68 type cots are used to spin yarn,the CV value,the average difference of line density,fine end,nub and nep indexes of the yarn can be significantly improved.
