摘　　要：文章研究了梳棉机锡林与刺辊速比变化对棉纱条干质量的影响问题。采用9档不同的刺辊速度进行测试,在每档刺辊速度下调节锡林速度,锡刺比分别为1.5、2.0及2.5时进行成纱条干对比试验。结果表明:(1)无论采用多大的锡刺比,刺辊速度均为600 r/min时有利于成纱质量的改善。(2)当锡刺比较低时,刺辊速度过小或者过大对成纱质量都会有较大影响,刺辊速度为500 r/min时最不利于成纱质量的提高。(3)刺辊速度小于750 r/min时,采用较大的锡刺比2.5有利于改善成纱质量;刺辊速度在800~850 r/min之间,采用锡刺比为2.0对成纱有利;但总体上锡刺比有增加趋势。(4)刺辊速度的选择不易过大,刺辊速度超过900 r/min时,对成纱质量影响较大。The influence of the speed ratio of cylinder and taker-in on the quality of textile strands is studied.Nine speeds of taker-in were used for testing,the cylinder speed was adjusted at each taker-in speed,and the yarn evenness comparison test was performed when the speed ratios between cylinder and taker-in were 1.5,2.0 and 2.5.Results show that:(1)no matter what speed ratios between cylinder and taker-in are,when the taker-in speed is 600 r/min,it is beneficial to the improvement of yarn quality.(2)when the speed ratio between cylinder and taker-in is relatively low,both too fast and too slow taker-in speed will have a greater impact on the quality of the yarn.And when the taker-in speed reached 500 r/min is the most unfavorable factor for the quality of the yarn.(3)when the taker-in speed is less than 750 r/min,the speed ratios between cylinder and taker-in reached 2.5 is beneficial to improve yarn quality;when the taker-in speed is between 800~850 r/min,the speed ratios between cylinder and taker-in reached 2.0 is good for yarn evenness.However,there is a general trend of an increase in the speed ratio between cylinder and taker-in.(4)the taker-in speed should not be too fast,when its speed exceeds 900 r/min,it will deliver a blow to the yarn quality.
