Abstract
The method and the facility for investigations of radiant characteristics (total emissivity, transparence and reflectance) of semi-transparent fabrics and films are presented.
The method is based on a measurements and comparison of effective emissivity of a test sample with two different opaque sublayers, whose radiant characteristics are known. These emissivity measurements are performed at the same temperatures. The determination of effective total emissivity of is carried out by means of the measurement of total radiant flux of a test sample with sublayer when ones are rotated in a heating isothermal zone with a controllable temperature. Facility permits to determine both the normal and hemispherical above radiant characteristics of semi-transparent fabrics and films in the temperature range from 300 to 900 K.
The investigation results obtained for three glass fabrics are presented.
