摘　　要：探讨锡林速度变化对生条、头并条、二并条中纤维长度分布的影响。用Premier的aQura棉结和短纤维测试仪测试了梳棉机不同锡林速度条件下所加工生条、头并条、二并条中的纤维长度分布。结果显示:棉卷经过梳棉机、并条机的加工后,6mm及以下纤维先是增加,随后逐渐减少,头并减少的幅度大于二并;>6mm^24mm纤维随着加工流程的进行逐渐减少,减少的幅度是梳棉机最大,头并次之,二并最小,规律性比较明显。24mm以上纤维虽也有损伤,但随着>6mm^24mm纤维的减少和牵伸过程的进行其比率不断增加。认为:通过梳棉机锡林速度对纤维长度分布的研究,有利于确定梳棉最佳锡林工艺速度。Influence of cylinder speed changes on fiber lengths in card sliver,first drawing and second draw-ing were discussed. Fiber length distributions of card sliver, first drawing and second drawing obtained in differentcylinder speeds of carding machine were tested by Premier aQura neps and short fiber tester. The test resultsshow that fiber quantity with length below 6 mm is increased firstly and decreased later when cotton lap is pro-duced by carding machine and drawing frame. The decrease range of first drawing is bigger than that of the seconddrawing. Fiber quantity with length of 〉 6 mm-24 mm is gradually reduced as the proceeding of processes. Theshort fiber reduce range in carding machine is the biggest,the first drawing is secondly,the second drawing is thesmallest,the regularity is relatively obvious. The fibers with length of above 24 mm are also injured but the inju-ring percentage is increased as the amount decrease of fiber with length about 〉 6 mm-24 mm and proceedingof drawing process. It is considered that the study of cylinder speed in carding machine affected fiber length distri-bution is beneficial to the confirmation of best cylinder speed in carding process.
