摘　　要：为了在环锭细纱机上使用加长上销纺制节粗倍数较大、节长较长的竹节纱品种,以精梳棉27.12 tex竹节纱为例,通过介绍配棉情况和工艺流程,分析其清梳、棉预并、条并卷、精梳、并条、粗纱、细纱各工序主要工艺参数设置及调整措施。指出:在配置竹节纱装置的FA502型细纱机上,使用加长上销、肇东下销和V型牵伸装置纺制环锭纺精梳棉27.12 tex竹节纱,应确保牵伸顺畅,防止出“硬头”和节中“大肚纱”;在细纱工序应采取稍大的后区罗拉隔距和后区牵伸倍数、适当的钳口隔距块、适度偏大的罗拉加压力、合适的钢丝圈以及适宜偏低的前罗拉转速等,在自络工序需采取较低的络筒速度和合适的电清工艺。In order to spin slub yarn with larger slub multiple and longer slub length using extended top cradles on ring spinning frame,taking combed cotton 27.12 tex slub yarn as an example,the setting and adjustment measures of the main process parameters of blowing-carding,cotton pre-drawing,drawing and lap combined,combing,drawing,roving and spinning processes are analyzed by introducing the cotton assorting situation and process.It is pointed out that when combed cotton 27.12 tex slub yarn is spun in the FA502 spinning frame equipped with slub yarn device and using extended top cradle,Zhaodong lower pin and V-type drafting device,smooth drafting should be ensured to prevent“hard head”and“big belly yarn”in the section.In the spinning process,slightly larger roller gauge and drafting multiple of the rear-zone,appropriate roller nip spacer,moderately larger pressure of the rollers,appropriate ring and suitable low speed of the front rollers should be adopted;while in the automatic winding process,lower winding speed and appropriate electric cleaning process should be adopted.
