棉纤维集合体电流弛豫的影响因素

Factors influencing current relaxation of cotton fiber assembly

为测试棉纤维电导性能和回潮率,利用自制散纤维压缩装置以及Lab VIEW的电流测试系统,研究了体积密度、电压、相对湿度以及温度对棉散纤维集合体电流驰豫的影响。通过实验发现:随着体积密度的增加,棉纤维集合体电流从峰值到稳定所需时间增加;随着测试电压的升高,纤维电流从峰值到稳定所需时间缩短;随着相对湿度的增加,纤维电流从峰值到稳定的时间缩短;随着温度的升高,纤维电流从峰值到稳定所需时间缩短。为了快速准确地获得纤维电导,测试时间需要根据棉纤维的集合状态,所施加的电压,空气温湿度而定。

In this paper,by means of self-made fiber compression device and current testing system based on Lab VIEW,effect of volume density,voltage,relative humidity and temperature on random cotton fiber assembly current relaxation was experimentally investigated.It was found that with volume density increasing,time of random cotton fiber assembly current from peak to stable value reduces to some extent.With the increase of voltage,time of current from peak to stable value decreases.With relative humidity and temperature raising,the time of current from peak to stable value shortens.In order to obtain the accurate fiber conductance,the testing time is considerably selected according to cotton assembly status,testing voltage,relative humidity and temperature.
