摘要：为了充分发挥清梳联优势，降低生条棉结和短绒含量，分析棉结成因及原棉成熟度、疵点、线密度以及回潮率等质量指标对棉结的影响，探讨清梳联工序各单机打手转速及工艺隔距对棉结和短绒的影响，用AIFS实验数据对各机工艺进行优化，强调清梳联合机组使用和维护要点。指出：清梳联质量控制是一项系统工程，应从原棉选配、工艺技术、运转管理等方面入手，加强工序试验和检验，将清梳联生条棉结和短绒控制在要求的范围内；根据设备技术特点和原棉内在质量，调整好清梳联各打手转速、选配好针布型号、优化各部隔距、维护并使用好设备，方能有效控制棉结和短绒，达到提高生条质量的要求。

Abstract:In order to give full play to the advantages of blowing-carding unit，and reduce the content of neps and short fibers of sliver，nep factors and the influence of quality indicators such as maturity，defects，linear density and moisture of raw cotton on neps are analyzed，and the influence of beater speed of each unit and process gauge in blowing-carding process on neps and short fibers are analyzed.Process of each unit are optimized with AIFS experiment datas,and operation and maintenance points of blowing-carding unit are emphasized.It is pointed out that the quality control of blowing-carding is a systematic project，which should be started from the aspects such as raw cotton selection，process technology，operation management to strengthen the process tests and inspection control，so as to control the neps and short fibers of blowing-carding in the required range.Adjusting the speed of all beaters of blowing-carding，choosing and matching the type of card clothing，optimizing the gauge of each part，and maintaining and using the equipments according to the technical characteristics of the equipments and the inherent quality of the raw cotton can effectively control neps and short fibers to improve the quality of the raw cotton.
