Abstract: This review elucidates the thermoregulation mechanism and performance testing methods of solid-liquid phase change materials. Subsequently, based on the recent applications of phase change microcapsules in smart temperature-regulating fibers and textiles, the research status and development trends of phase change microcapsules are summarized, aiming to provide reference for the expanded application of phase change microcapsules in the textile field.

Key words: phase change temperature-regulating materials; microcapsules; smart temperature-regulating textiles; smart temperature-regulating fiber; finishing
