Abstract

A new computer controlled device ALAMBET A to measure the thermal  properties of flat woven and nonwoven textiles was developed at the technical  University in Liberec. Within one measuring operation taking no more than two  minutes it yields the values of thermal resistance, conductivity, and diffusivity  thickness of the sample and its thermal - contact characteristic, the thermal  absorbtivity expressing the warm - cool feeling of the fabric [4].  
By means of this instrument the thermal parameters of up to five layers of  identical woven and nonwoven fabrics were investigated.  
The following results were found :  
1· Thermal resistance increases with the total thickness linear (for "NW" fabrics)  or slower. The highest value exhibits "NW'' out of textile wasters the lowest  PAD and Vs fabrics.
2· Thermal absorbtivity  theoretically does not depend on the thickness [4]. The  experiments confirm that thermal absorbtivity varies with the thickness  unsubstantially. The highest increase (for eight layers of NW) presents  104.7%.  
3- Thermal conductivity increases with the thickness substantially slower than  linear [2]. The highest values of thermal conductivity exhibit PAD, then Vs  and PES while the lower level belongs to "NW" out of textile wastes.
