摘　　要：为检验不同型号分梳辊的分梳质量,介绍分梳辊分梳牵伸的特点和分梳辊分类;从纺纱器结构、气流控制和分梳辊速度等方面详述其对分梳牵伸的影响;分别选用7种不同规格的分梳辊用齿条,采用棉纤维及表面更光滑、截面更接近于圆形的莱赛尔纤维进行对比试验,并用纤维损伤频率差异分析法对纤维损伤度进行可靠性验证。结果表明:除齿密最小的G型分梳辊外,棉纱线的整体质量基本上随着分梳辊针布齿密的减小而逐渐恶化;成纱质量除与分梳辊型号相关外,还受到齿部几何形态、表面粗糙度及其与喂棉机构、排杂通道及输纤通道内气流状态的适应性等综合因素的影响;分梳辊针布齿条表面粗糙度的差异对纤维损伤的影响较小,但对纱线质量影响较大。In order to test the carding quality of different types of carding rollers,the characteristics of carding draft of carding roller and classification of carding roller are introduced.The influence of carding roller on carding draft is described in detail from the aspects of spinning box structure,air flow control and carding roller speed.Seven kinds of rack for carding roller are selected,and the lyocell fiber with smoother surface and more circular cross section and cotton fiber are used in the comparative test,the reliability of the fiber damage degree is verified by the fiber damage frequency difference analysis method.The results show that the overall quality of cotton yarn basically deteriorates with the decrease of the tooth density of card clothing,except for the G-type carding roller with the smallest tooth density,and the yarn quality is related to the type of carding roller,it is also affected by tooth geometry,surface roughness and its adaptability to feeding mechanism,exhaust channel and air flow state in fiber transport channel;the difference of the surface roughness of the rack for card clothing in the carding roller has little effect on the fiber damage,but has great effect on the yarn quality.
