Abstract:

Pure PCM and microencapsulated PCM (µPCM) were analysed for heat capacity and core content using DSC analysis and were tested for stability against heat and solvent. The energy release rate of human feet was quantified through a novel in-house tester using a water and air medium. The energy release rate from various experiments were compared and ranges of the quantity of µPCM recommended for a definite period of thermoregulation with and without a factor of safety. Based on theoretical predictions, socks were treated with µPCM at add-on values of 0.2 g to 5 g corresponding to 1 % and 25 % per weight of the socks, respectively. The socks treated were subjected to wear trials and evaluated against the untreated one. It was found that the thermoregulation period of the µPCM treated socks were proportional to their add-on weight and were in close agreement with the theoretical predictions proposed. The presence of µPCM on the treated socks was observed through a scanning electron microscope.
