1. High sensitivity measurements of thermal properties of textile fabrics

Author

Romeli, D., Barigozzi, G., Esposito, S., Rosace, G., and Salesi, G.

Subjects
Physics - Instrumentation and Detectors, Condensed Matter - Materials Science
Abstract

A new testing apparatus is proposed to measure the thermal properties of fabrics made from polymeric materials. The calibration of the apparatus and the data acquisition procedure are considered in detail in order to measure thermal conductivity, resistance, absorption and diffusivity constants of the tested fabric samples. Differences between dry and wet fabrics have been carefully detected and analyzed. We have developed a new measurement protocol, the "ThermoTex" protocol, which agrees with the UNI EN 31092 standard and entails an accurate quantification of the experimental errors according to a standard statistical analysis, thus allowing a rigorous investigation of the physical behavior of the phenomena involved. As a consequence, our machinery exhibits great potentialities for optimizing the thermal comfort of fabrics, according to the market demand, thanks to the possible development of a predictive phenomenological theory of the effects involved., Comment: RevTeX4 source file; 9 pages, 9 figures
