Can polyester fabric be engineered with phase-change materials for thermal regulation?

Polyester fabric, widely used for its durability and affordability, can indeed be engineered with phase-change materials (PCMs) to achieve advanced thermal regulation. PCMs are substances that absorb, store, and release heat as they change phases (e.g., from solid to liquid), making them ideal for temperature management in textiles. By integrating PCM microcapsules into polyester fibers or coatings, the fabric gains the ability to regulate body temperature, keeping the wearer comfortable in varying climates.

This innovation is particularly valuable in sportswear, outdoor gear, and even medical textiles, where maintaining optimal thermal balance is crucial. Research shows that PCM-enhanced polyester fabrics can significantly improve thermal comfort by reducing temperature fluctuations. However, challenges such as durability after repeated washes and cost-effectiveness remain areas for further development.

In summary, polyester fabric combined with phase-change materials represents a promising advancement in smart textiles, offering enhanced thermal regulation for diverse applications.
