摘　　要：介绍了纺制竹节纱的紧密纺细纱机机械结构改造的特点。对已加装了ZJ-5型竹节纱装置的EJM128K-SM型细纱机进行四罗拉紧密纺纱技术改造后,采用正交试验方法对基纱特数为CJ14.6tex的竹节纱纺纱工艺参数——锭速、前胶辊加压量、网格圈目数、吸风负压进行了优化设计,得到合理工艺配置为锭速10 000r/min、前胶辊加压160N/双锭、网格圈的目数3 600目/cm^2、吸风负压2 800Pa。This paper introduces the features of the modified mechanical structure of the compact spinning frame for spinning slubby yarn. The EJM128K - SM compact spinning frame added with ZJ - 5 slubby yarn device was reconstructed for 4 rollers compact spinning by using orthogonal test method to optimize the spinning parameters of CJ9. 7tex slubby yarn spindle speed to be 10 000r/min, front rubber- covered roll pressure to be 160N/double spindle, mesh of lattice circle to be 3 600/cm2 and suction negative pressure to be 2 800Pa.
