[Substantiation of physiologic and hygienic requirements of heat-proof properties of winter headgear].
Experimental studies conducted in cooling environment assessed the features of heat exchange and thermoregulation of head during physical work varying in hardness and type. The studies determined allowable parameters of heat exchange on head (skin temperature and surface heat outflow), which are necessary for construction and evaluation of headgear. The article presents correlations between main heat-proof parameters of headgear (total heat resistance, thickness of materials and their permeability to air). The data of experimental and industrial trials helped to elaborate physiologic and hygienic requirements for heat-proof headgear in various climate conditions.
