Phase change materials (PCMs) are increasingly integrated into textiles to significantly enhance thermoregulation by absorbing and releasing latent heat during their phase transitions. This advanced technology promises to improve thermal comfort for individuals and boost energy efficiency in various applications, including buildings and vehicles. Its crucial role extends to specialized areas such as sportswear, medical textiles, and protective gear, where precise temperature control is paramount. Ongoing research efforts are dedicated to optimizing the encapsulation of PCMs, ensuring their uniform dispersion within textile fibers, and guaranteeing their durability through repeated washing and wear. The overarching development goal is to create cost-effective, sustainable, and scalable textile-based PCM solutions that meet diverse market needs. This study explores the synthesis and application of microencapsulated phase change materials (MEPCMs) specifically for thermoregulating textiles. It delves into detailed methods for creating stable MEPCMs possessing desirable thermal properties and discusses their effective incorporation into various textile structures, including coatings and yarn spinning. The research highlights the critical impact of factors such as PCM loading, particle size, and the choice of encapsulation shell material on the overall thermoregulation performance, as well as on essential fabric properties like washability and breathability. The integration of paraffin-based microencapsulated phase change materials (PCMs) into polyester fabrics is a key area of investigation aimed at achieving substantially enhanced thermal comfort.
