[Effect of various furniture covering fabrics on heat regulation and comfort].
The effects of three different materials for furniture fabrics (wool, polyacrylonitrile and Skai) on thermophysiological parameters and comfort were studied. In a laboratory design male, middle aged subjects were tested three times for three hours in a climate chamber, being exposed to internal and external thermal strains as well as to stress inducing situations. The outcome of this research suggests an essential influence of the structure of the tested materials but only small influences by the kind of fibres. The test situation "Skai" induced markedly different effects on skin temperature, skin moisture level and self rated thermal comfort as compared to both textile materials: A high sweat secretion followed by a continuously increasing moisture accumulation could be observed, especially for areas of the body surface which were tight contact with the material. Simultaneously a distinct skin temperature decrease at the back was found, which can be interpreted as a consequence of a high heat conduction due to the material itself as well as by sweat vaporization when the back was lifted from the backrest. The differences between the natural fibre- and synthetic fibre materials were generally small and occurred merely under heat stress conditions, where a pronounced reactivity of skin temperatures, skin moisture and heart rate could be observed testing the synthetic textile material. Being asked about thermal comfort, the subjects attributed their ratings to uncomfortable room climate conditions rather than to properties of the materials on which they were seated.
