In order to determine the improvement in thermal comfort resulting from the PCM application in clothing protecting against foul weather, controlled wearing trials in a climatic chamber have been performed. Loose fitted jackets made of waterproof breathable fabric were selected as experimental garments. Three different nonwovens containing microPCMs were inserted in the test jackets. The set of identical jackets but without microPCMs were tested. Four young healthy men participated in wear trials as test subjects for each clothing system and each ambient temperature, at periodically changed physical actvity. The wearing trials were conducted at an ambient temperature 0°C and -10°C and relatve humidity 25%. During the test skin temperatures at four sites (chest, back, arm and hand) were recorded. Additional information were derived by measuring the body mass loss. Subjective ratings of the thermal and overall comfort sensations were obtained during the experiment. The test results demonstrate that nonwavens containing microPCMs improve the clothing microclimate, which can lead to a greater feeling of comfort. The improvement of microclimate is proved by smaller change of the chest skin temperatures and lower amount of moisture generated by the skin. The results of measurements are supported by subjective statements about comfort. The study reveals that the ability of nonwoven containing PCM to buffer the heat is influenced by the ambient temperature.
