粗纱卷绕外径递增规律探讨

Discussion on outside diameter increment of winding roving package

由于新型粗纱机在高速等情况下不断增大粗纱卷装,针对粗纱卷装最终纱层厚度与最初纱层厚度的关系与传统理论相比是否发生变化的问题,根据粗纱纱层厚度按照等差级数递增的规律,运用测量粗纱卷装周长的办法测试粗纱卷绕外径,将所测数值运用MatLab拟合出粗纱卷绕外径与纺纱层数之间的关系方程式,方程相关系数达到99.99%。研究认为,所得最终纱层厚度是最初纱层厚度的倍数值由原来的1.3变为1.33～1.60,表明粗纱机卷装容量的增大使得最终纱层厚度与最初纱层厚度之间的关系发生了新的变化。

The high speed operation of the roving frame results in the size of roving package increasing continuously.Under these circumstances,a question is posed,that is,whether the traditional theory still applies to the relationship between the initial roving layer thickness and the final roving layer thickness.This paper discussed this question based on the roving layer thickness increasing in accordance with the laws of arithmetic progression,measured the outside diameter of winding roving package through measuring the perimeter of the winding roving package,and then used MatLab to fit the data measured and figured out the equation governing the relationship between the outside diameter of winding roving package and the number of roving layer.The equation′s correlation coefficient reached 99.99%.The results showed that the times between the final roving thickness per layer and the initial roving thickness per layer changed from 1.3 to 1.33 ～ 1.60.This indicated that due to the increase of roving package size,a new change has occurred with the relationship between the initial roving layer thickness and the final roving layer thickness.
