Determination of anistropic wetting property of fabric by wet resistance method

According to the mutation of fabric resistance when it is wet,we have made an apparatus for testing the anistropic wetting property of the fabric using a metal probe as sensor.This apparatus can simultaneously determine the moisturizing of water along warp,weft and 45° directions of the fabric.The test results reveal that apart from the fabric varieties and weaves,the diffusing rate of water is related to fabric thickness,and the direction of diffusing.There exists a linear relationship between the square of diffusion displacement and the time of diffusion.
