A semi-empirical model of the relative contact area of woven fabrics has been developed. Its output is implemented into a multiple linear regression model of thermal absorptivity of 100% cotton woven fabrics as a predictor, together with open area, areal density, thickness and fabric density. Validation of the thermal absorptivity model shows that the contribution of the relative contact area and its interaction term with areal density generates lowest values of the mean and maximum percentage errors, indicating good predictability of the thermal contact feeling. The model is not applicable for nonwovens.

预测单层棉织布热吸收率的相对接触面积模型的建立

建立了机织物相对接触面积的半经验模型。它的输出被实现为100％棉织物的热吸收率的多元线性回归模型，以及开口面积，面密度，厚度和织物密度，以此作为预测指标。热吸收率模型的验证表明，相对接触面积及其与面密度的相互作用项的贡献产生了均值和最大百分比误差的最小值，表明热接触感觉的良好可预测性。该模型不适用于非织造布。
