One of the most extensively used textile materials is polyester, which comes in a variety of textile, yarn, and fiber forms. This is dependent on the characteristics of the polyester polymer and its intended usage of it. To give different polyester fabrics, the ability to change their thermal state over a wide range and be used for thermal protection for a variety of purposes, regardless of ambient temperatures, this research aims to improve the thermal heat profiles for those fabrics when constructed with Phase Change Material (PCM). To create PCM composite treatment materials, various polyester fabric constructions were simply treated utilizing Octadecane as (PCM material) loaded on alginic/stearic acid. Following treatment with the KES thermal conductivity system and Differential Scanning Calorimetry (DSC), the textiles' qualities were assessed, and their physicomechanical properties were also looked at. Conclusion: Polyester textiles can be coated with PCM composites, and the covered version performs better than the uncovered version. Additionally, it was found that these treatments improved the mechanical and physical qualities but had no effect on the permeability to air and water vapor following examination of the attributes of blank/uncovered and covered polyester textiles.
