To spinning C 102. 1 tex slub yarn used in carpet successfully, cotlon was assorted rationally, roving weight per unit was optimized, larger roving twist factor was adopted, processing of lower speed, larger twist, heavier weight,larger nip,larger draft in back draft was adopted in spinning process,ring with larger diameter and proper shape ring traveler with heavier weight were used,slub yarn parameter suiting carpet style was selected. Lower winding speed and knotter were adopted in winding process,finally C 102. 1 tex slub yarn can be produced successfully,the yarn quality and slub style can reach use demands.%为顺利纺制地毯用特粗号C 102.1 tex竹节纱,在生产中,通过合理配棉,优选粗纱定量,采用较大的粗纱捻系数；细纱工序采用“低车速、大捻度、重加压、大钳口、大后区牵伸”工艺,同时选用大直径钢领、合适圈形且偏重的钢丝圈、适宜的级升卷绕、符合地毯用竹节纱风格要求的竹节工艺参数；络筒工序采用较低的络纱速度、打结器接头等技术措施,最终顺利生产出C 102.1 tex竹节纱,其成纱质量和竹节风格也满足了使用要求.
