Abstract:

In order to build an effective prediction model of moisture resistance of single-layer and double-layer combined sportswear knit fabrics in soft wind range, twelve T-shirt fabrics and eight outerwear fabrics which are commonly used were selected for this study. The moisture resistance of fabrics under four wind speeds was tested, and the representative T-shirt and outerwear fabrics were obtained by cluster analysis. By simulating the two-layer dressing state of T-shirt and outerwear, quantitative test of moisture resistance between skin, T-shirt and outerwear under different wind speeds were carried out.The third-order polynomial model of the moisture resistance of T-shirt and outerwear fabric and wind speed, and the linear model between the moisture resistance of double-layer fabrics combination and the moisture resistance of inner and outer layer fabric were constructed. The results show that the moisture resistance of T-shirt, outerwear and double-layer fabrics combination decreases with the increase of wind speed within the range of soft wind, and the moisture resistance of the inner T-shirt fabric has a greater impact on the moisture resistance of the double-layer sportswear fabric combination. The mean absolute percentage error of the prediction models of moisture resistance of T-shirt and outerwear fabric is 2.22% and 4.85% respectively, and the mean absolute percentage error of double-layer fabrics combination moisture resistance model is 3.20%.

Key words: wind speed, sportswear, knit fabric, moisture resistance, prediction model of moisture resistance
