The “chilling effect,” or “clamminess,” that moist fabrics produce when in contact with the body was evaluate by subjective tests, by measurement of the drop in temperature that ensued when the moist fabrics were placed on an artificial “skin” surface, and by tests with a moisture-sensitive paper designed to measure the extent of contact which the fabrics made with a surface. Using fabrics of various fiber compositions and constructions, a good qualitative relation was found in these tests. Fabrics which produced considerable chilling in subjective tests were found to make good contact and to cause a substantial drop in skin temperature. Conversely, fabrics which caused little or no clamminess made poor contact and the accompanying drop in temperature was relatively small. The results of these experiments show clearly the progressive improvement of the fabrics with respect to chilling, as their wool contact is increased, and also the superiority of certain types of construction that minimize the extent of contact of the fabrics with the skin.
