提高R9.8 tex成纱质量的生产实践

Production of Improving R9.8 tex Yarn Quality

为了提高R 9.8 tex成纱质量,通过原料选配并对其进行纺前预处理以提高原料可纺性,优选各工序主要工艺参数配置,如棉卷定量、打手速度、梳理隔距、针布型号、并条牵伸工艺、粗纱捻系数、细纱罗拉隔距、纺纱胶辊、钳口隔距、后区牵伸等措施,最终使R 9.8 tex纱的成纱质量得到明显改善。

To increase R 9.8 tex yarn quality, the raw material and fore-spinning pretreatment were selected to im- prove raw material spinnability. Main technology parameter in each process were optimized, including lap weight per u- nit, heater speed, carding gauge, card clothing type, draft processing in drawing, roving twist factor, roller gauge in spin- ning, rubber-covered roller, nipper gauge, draft in back zone et al. finally quality of R 9. 8 tex yarn can be improved obvi- ously.
