Relation between the Reflectivity and the Moisture Content of the Dynamic Moisture Transfer of Fabrics

Abstract:

In this paper, we used spectrophotometric measurement to get the reflectance values of experimental samples and discussed relation between the reflectivity and the moisture content. By measured curves of reflectivity and the wavelength of 47 samples from 0 to 30 minutes we had found that the reflectance difference was the largest when the wavelength in the 600-700nm wavelength,it could help us to distinguish dynamic surface moisture performance at different time points, so, the paper had selected the reflectivity in wavelength 650nm as the feature value. Using the reflectance had established the linear model of moisture content, the results showed that: R² value of the determination coefficient of the linear regression model is 0.9979, almost close to 1, it had indicated that the reflectivity as the feature value could be used to predict fabric moisture content.
