摘要：

This article takes into consideration some constructive parameters of needled nonwoven fabrics used as padding in winter clothes, and their influence on thermal resistance Rct and water vapor resistance Ret. The nonwoven fabric features taken into consideration were the following: substance fibers, their average linear density, and their bulk density. Nonwoven fabrics examined had a fiber content varying from 0.5% to 4% of the total volume of the sample. In these particular conditions, the results obtained showed that the fiber substance has little influence on Rct and Ret. Instead, the average fiber linear density and bulk density of nonwoven fabrics are very important for an accurate design in order to optimize comfort performance.
