Thermal Comfort of Woolen Fabrics Depending on Physical Properties

ABSTRACT

In this study, thermal comfort properties of woolen fabrics depending on the physical properties have been investigated. Thermal and water vapor resistance of fabrics have been measured by the PERMETEST instrument and air permeability has been investigated in a wind tunnel. The air permeability depends on the shape and value of the pores and inter thread channels, which are dependent on the structural parameters of the fabric. Theoretical model has been used in order to determine the porosity values. Experimental data and regression statistics proved that porosity and other fabric parameters have a very strong influence on thermal comfort property.

摘要

本文根据不同的物理性质对羊毛织物的热舒适性进行了研究。织物的热阻性和水蒸汽阻性由PERMETEST仪器测定，透气性在风洞进行测定。透气性取决于孔隙和内部线道的形状和值，后者依赖于织物的结构参数。本文使用了理论模型以确定孔隙度值。实验数据和回归统计证明，孔隙率和其它织物参数对热舒适性有很大的影响。
