Textile containing Phase Change Materials (PCMs) provide thermal protection against extreme weather. When the temperature rises, the materials absorb heat by melting and store that energy for later use, providing thermal comfort. In this paper heat transfer analysis of yarn containing 4% Microencapsulated PCMs has been studied using finite element analysis. The heat flow property of yarn has been studied and validated with experimental results obtained from Differential Scanning Calorimetry showing correlation coefficient of 96.39%. Based on the validated model, it was further studied with yarns containing 10% Microencapsulated PCM and a core sheath structure to predict the thermal properties of yarn which cannot be determined experimentally. Delay in temperature rise over time due to the presence of PCMs has been studied using a commercial software ABAQUS/CAE through post processing calculation and will be described in the paper.
