The increasing of the air temperature in the earth surface encourages the using of Phase Change Materials (PCM) to store the thermal energy and increases the time constant from the heat transfer system. Microencapsulated PCM could be integrated to textile fiber to achieve the thermal comfort for the human body. The addition PEG1000 microcapsules to the cotton fabrics usually do not giving significant influences to the thermal capacity of the cotton fabrics. Some experiments were conducted in this study, such as PEG1000 microencapsulation using Urea-Formaldehyde resins and identified the influences of the addition of synthesized microcapsules to the heat capacity of the cotton fabrics. The microcapsules synthesized by add the melted PEG1000 to the Urea-Formaldehyde to initiate the polymerization of the resin. The microcapsules synthesized by two methods. After being synthesized, the microcapsules “glued” to cotton fabrics using Citric Acid Exhaustion methods. The synthesized microcapsules characterized by SEM, TEM, DTA, and DSC. After coated to cotton fabrics, the influence of the addition of microcapsules to the heat capacity of the cotton fabric were identified. The influences of washing the coated textile to the adhesives of microcapsules also identified by DSC and DTA. In this study, the character of PEG1000 microcapsules and it’s influences to heat capacity of cotton fabrics satisfied the objective of the study.
