They are used primarily to make clothing. provide better evaporation evaporation, change of a liquid into vapor at any temperature below its boiling point. For example, water, when placed in a shallow open container exposed to air, gradually disappears, evaporating at a rate that depends on the amount of surface exposed, the humidity of moisture they don't have any effect on your body's ability to cool itself or even your perception of comfort. In the study, eight men performed three different bouts of exercise wearing shorts, t-shirts and socks of evaporative evaporative pertaining to evaporation. evaporative loss loss of body water by evaporation of water from the body to the air; a heat control mechanism and a factor in water balance studies. polyester fabrics, cotton fabrics, or semi-nude (wearing just a nylon bathing suit). The exercise consisted of 15 minutes seated rest, running in moderate heat (85[degrees]F and 35% humidity) for 30 minutes at 70% VO2max and 15 minutes walking at 40% VO2max, and another 15 minutes of seated rest. The men had a lower skin temperature in the semi-nude condition while seated before exercise. Otherwise there were no differences in skin temperature, body temperature, or core body temperature during or after exercise among any of the clothing options. There were also no differences in VO2, heart rate, or in reported comfort.
