提高CJ9.7tex纱条干均匀度的生产实践

Practice of Improving the Evenness Uniformity of CJ 9.7 tex Yarns

介绍了纺制CJ9.7tex高支纱的工艺技术,着重对并、粗、细的工艺参数进行了优选,提出了提高成纱条干均匀度的措施.精梳工序提高纤维的平行度和分离度,并条的总牵伸倍数大于并合数,粗纱高捻,细纱工序采用合适的牵伸元件,确保了成纱条干的均匀.

This paper introduces the process technology of spinning the CJ 9. 7 tex extrafine yarns,emphasizes the advisable selection of drawing,rove and spinning technical parameters,and brings forward the measure of improving the spinning evenness uniformity. Combing process improves the degrec of parallelization and separation of fiber,the total amount of draft in drawing is more than the number of doubling,roving uses hard twist and spinning process adopts fit drafting components to insuve the evenness regularity of resultant yarn. 
