摘　　要：为了稳定精梳产品质量,以纺CJ 7.29 tex纱为例,介绍精梳梳理工艺试验条件、工序质量要求,通过分析预并条工序、条并卷工序、精梳准备工序的主要作用、工艺设置对工序质量的影响,总结各工序的工艺控制要点,并进行纺纱实践及成纱指标对比;从锡林(弓形板)精准定位、分离罗拉顺转定时、精梳落棉隔距设定等方面阐述精梳机工艺调整要点及注意事项。指出:半制品质量直接关系成纱指标;精梳工艺设置需结合前后道工序质量综合考虑;预并条工序重点考虑弯钩纤维的伸直和避免长纤维的意外拉断;条并卷工序棉卷成形要良好、均匀;精梳工序注重梳理效果和梳理效率;精梳工艺设置结合质量要求及纺纱环境,保证设备、器材、专件等状态良好,各部件定位定时以及隔距设置精准;通过试纺优化工艺后,成纱质量指标改善。In order to stabilize the quality of combing products,taking spinning CJ 7.29 tex yarn as an example,the experimental conditions and process quality requirements of combing process are introduced,by analyzing the main functions of pre-drawing process,drawing and lapping process,combing preparation process and the influence of process settings on process quality,the key points of process control for each process are summarized,the spinning practice and yarn index are compared.The key points and matters needing attention in the process adjustment of comber are described from the aspects of precise localization of cylinder(bow plate),forward motion timing of detaching roller and setting of comber noil gauge.It is pointed out that the quality of semi-finished products is directly related to the yarn index,setting of combing process should be considered in combination with the quality of the previous and subsequent processes.Pre-drawing process should focus on the straightening of hook fibers and the avoidance of unexpected pull-off of long fibers,the lap should be formed well and evenly in the drawing and lapping process,the combing process should pay attention to the carding effect and carding efficiency.Combing process should be set up according to the quality requirements and spinning environment to ensure the good condition of equipment,accessories and parts,ensure the accuracy of positioning,timing and gauge setting of each part.The yarn quality index is improved by optimizing the trial spinning process.
