Phase change materials (PCMs) are used to achieve latent heat storage or release from a material. The storage of latent heat or thermal regulation is based on the transition of material undergoes phase changes from solid to liquid, liquid to gas or vice versa. PCM has the ability to absorb and release heat from surroundings in dynamic heat exchange processes. A wide range of PCMs can be classified into two types such as organic PCMs and inorganic PCMs with different storage heat capacity and temperature. A most example of PCMs is the paraffin wax. The PCMs cannot be integrated in to textile materials directly due to some extent disadvantages. The PCMs are enclosed in microcapsules for textile application. In recent years, the use of PCMs in heat transfer application incorporated with textile substrates is quantitatively enormous. Therefore, in this paper, the principle of PCMs, microencapsulation techniques and areas of applications in textiles are discussed.
