Paraffin is often used as an organic phase change material PCM incorporated in textiles for enhancing said texiles’ thermal behavior. This material is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy In this paper, two different densities of jute fabric was used. These phase changes take place at constant temperature and for certain materials the process of melting and crystallizing can be repeated over an unlimited number of cycles with no change to their physical or chemical properties. The aim of this work is to study the influence of structural jute fabrics treated with PCMs microencapsulated on thermal behavior, to carry aout the study two plain fabrics with different structural characteristics were used. Thermal behavior of both untreated fabrics was tested by balancing it above a heating plate. Consequently, the fabrics were measured with a TESTO 865 thermal imager. Afterwards, treated samples both with and without PCMs in printing paste were tested in the same way. The wanted effect was reached during cooling cycle of both textiles. Only the heating cycle of the treated lightest jute sample was found to be warmer than the untreated sample. More experimental testing is needed on this sample. Furthermore, the heating cycle of the densest jute sample was according to the expectations.
