Abstract:
From theoretical considerations a new clothing parameter, moisture permeability index, has been developed. The existing clo formula relating dry clothing insulation and ambient temperature to mans heat loss has been extended to include evaporative heat transfer. This extension indicates a range over which the clothed man may maintain thermal equilibrium. This concept of range applies in all types of environments and thus one theory is applicable to hot, temperate, and cold environments. The theory also indicates the limitations of sweat evaporation as a cooling mechanism. A method is described for measuring moisture permeability index.
