摘　　要：粗纱后区牵伸的作用是承担部分总牵伸,同时为前区牵伸作准备,由于后区为简单罗拉牵伸,若工艺设置不当,会直接影响粗纱的成纱质量。针对粗纱工序后区牵伸隔距与牵伸倍数对纱线条干的影响进行了研究,利用回归分析法设计试验,并通过专用数学统计软件MATLAB进行数据结果分析,得出了粗纱工序后区牵伸配置影响粗纱和细纱条干CV值的回归方程,并且由此方程可以对粗纱和细纱的条干CV值做出预测,从而为粗纱工序后区牵伸工艺控制和质量预测提供依据。The back zone draft of the roving working procedure can take part of overall draft,as same time can prepare for the front zone draft.Because the back zone draft is simple roller draft,if its technology is not reasonable,the yarn quality will be affected.The paper researched the infection of yarn levelness from the back zone draft distance and multiple,adopting the multivariate linear regression analysis and MATLAB,the yarn levelness regression equation was obtained,the equation’variables are the back zone draft distance and multiple,from the equation,the yarn levelness can be forecasted,so the basis of technology control and quality forecating of the roving working procedure was provided.
