Abstract
Abstract A cooling cap (1) made up with knitted net fabric of polyester yarn comprises an outer open-meshed fabric (3) for covering the front half part of the hemispheric part of the cap to receive the human head, an inner fine linen fabric (4) for lining the outer open-meshed fabric, a water absorbent fiber layer (5) for bearing water or absorbing sweat, and a plurality of eyelets or loopholes (6). The head is cooled owing to the vaporization of the water borne in the water absorbent fiber layer by absorbing the heat.
