【摘要】 羊毛交叉长度是毛纺生产中确定各道工序牵伸总隔距的依据,牵伸总隔距最终影响纤维条牵伸后的条干均匀度,快速准确测得交叉长度对毛纺工艺的制定至关重要。为此,利用梳片式纤维长度分析仪测试原始数据,在理论分析和逻辑推导的基础上,运用Excel软件绘制羊毛长度分布数字排列图,并通过添加趋势线得到多项式曲线回归方程。该方程的拟合精度相关系数达到0.994,其测试结果与传统手工排图法相比,误差率只有0.77%,可以认为羊毛交叉长度数字化测试法方便快捷,准确高效。更多还原

【Abstract】 In the wool spinning productiton,the determination of drawing gages for the series yarn production processes is based on the wool cross length,and the drawing gages will finally have influences on the drawn sliver evenness. Therefore,it is critically important for the yarn production technology to obtain the wool cross length with high efficiency and precision. This paper takes the comb sorter test wool length as original data,and on the basis of theoretical analysis and logic reduction,a digital wool length distribution array curve is obtained with Microsoft Office Excel. And through adding a tendency curve,a high precision polynomial curve regression equation with a relative ratio up to 0. 994 is achieved,and the deviation ratio of the testing result is only 0. 77% compared with conventional manual length distribution method. Testing of the wool cross length with the digital method has advantages of convenience,high speed,precision and high efficiency.更多还原
