摘　　要：文章介绍了压力棒的牵伸机制,并对纺纱过程中易出"硬头"问题原因进行分析。通过从粗纱捻系数、后区牵伸倍数、罗拉隔距、钳口隔距和摇架压力五个方面进行工艺优化调整,解决出"硬头"问题,提高了成纱质量。The drafting mechanism of pressure bar was introduced,and the cause of hard end was analyzed.Though optmizing technology of adjusting roving twist factor,draft multiple in back zone,roller gauge,nip gauge and press of top arm,the problem of hard end was solved,the quality of spun yarn was improved.

关 键 词：压力棒 隔距块 工艺优化 成纱质量
