This study focused on assessing the thermal comfort properties of the fabrics incorporating microencapsulated phase change materials (microPCMs) under steady-state condition. Air permeability and water vapor permeability of the fabrics were also investigated. Poly(methyl methacrylate)/n-hexadecane microcapsules were applied to the cotton and cotton/polyester fabrics using pad-cure methods. Thermal comfort properties of the fabrics were measured using Alambeta. The results indicated that the thickness of the fabrics incorporated with microcapsules increased depending on the amount of microcapsules added on the fabric. Thermal conductivity of the fabrics treated with polyurethane (PU) resin decreased while addition of microPCMs had almost no effect on the thermal conductivity. However, thermal resistance of the fabric increased as the fabric thickness increased or the thermal conductivity decreased. Air permeability and water vapor permeability of the fabrics treated with microPCMs were found to be lower than those of pristine fabrics while water vapor permeability of the fabrics treated with PU was found higher than pristine fabrics.
