针织物厚度与保暖性能关系建模分析

Modeling the Relationship Between Thickness and Warmth Retention of Knitted Fabric

以针织绒类织物为主,对32种不同原料、不同结构的针织物以及1种梭织物进行保暖性能测试与分析,探讨织物的克质量、厚度和透气性与织物克罗值之间的关系,并采用多元回归方法对其进行分析。结果表明,织物的克罗值与织物厚度和克质量之间存在线性关系,且织物克罗值与织物厚度的线性关系较强,得到克罗值与厚度的线性回归方程式,并根据回归方程预测织物样品的保暖性,预测值与实测值基本吻合。

Mainly for study of knitted velvet fabric, the warmth retention properties of 32 kinds of knitted fab-rics with different raw materials and different structures and a woven fabric were tested and analyzed. The relation-ship of fabric weight, thickness and air permeability with the CLO value of the fabric were discussed and analyzed by using multiple regression method. The results show that there is a linear relationship between the CLO value and the thickness as well as the weight per square meter of the fabric, and the linear relationship between the CLO val-ue and the thickness is strong. The linear regression equations of CLO value and thickness are obtained and used for predicting the warmth retention of the samples, and the predicted value is consistent with the measured value.
