摘要:为了解决并条工序出现机械波导致条干均匀度恶化,从而增大细纱条干CV值、降低织物外观质量的问题,介绍并条工序常见的两种机械波,即胶辊机械波(12 cm机械波)和传动系统机械波(76 cm机械波)的成因,通过末道并条工序波谱图和对应粗纱工序波谱图分析两种机械波对后工序的影响,探讨圈条效应引发机械波对粗纱的影响。指出:并条工序12 cm机械波和76 cm机械波均源于末道并条工序,更换末道并条工序前胶辊,修复后罗拉接头可消除机械波;由圈条效应引发的机械波对粗纱无明显影响;应高度重视并条工序机械波,及时排查生产中的机械故障,以稳定成纱质量,保证织物外观品质。

Abstract:In order to solve the problems such as mechanical waves in drawing process resulting in deterioration of evenness uniformity,actually increasing the yarn evenness CV value,and reducing the appearance quality of fabrics,the factors of two common mechanical waves in drawing process including cot mechanical wave of 12 cm and mechanical wave of 76 cm in transmission system are introduced.The influence of the two mechanical waves on the following process is analyzed by the spectrum in final drawing process and the corresponding roving process.Case analysis is done to the effect of mechanical wave induced by coiling effect in roving.It is pointed out that the mechanical waves of 12 cm and 76 cm in drawing process result from the final drawing process,so replacing the front cots in the final drawing process,and repairing rear roller joints can eliminate the mechanical waves. The mechanical wave resulting from coiling effect has no obvious effect on roving.Great attention should be paid to the mechanical wave in drawing process and timely troubleshooting in production is necessary to stabilize the yarn quality and ensure the appearance quality of fabrics.
Key Words:drawing;cots;mechanical wave;coiling effect;the value of evenness CV
