Abstract:

in this paper, by means of self-made fiber compression device and current testing system based on LabVIEW, 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 by cotton assembly status, testing voltage, relative humidity and temperature.
