The Technology Behind Cooling Fabrics

Specialized Fiber Design: Cooling fabrics may utilize fibers with specialized cross-sectional shapes, such as profiled fibers. These fiber structures increase surface area, promote air circulation, and accelerate sweat evaporation, thereby removing heat from the body. Some fibers contain microcapsules encapsulating cooling ingredients. When the fabric comes into contact with the skin, the microcapsules gradually burst, releasing cooling substances and creating a cooling sensation.

Moisture Absorption and Heat Dissipation: Some cooling fabrics work by utilizing the fiber's inherent moisture absorption and perspiration-wicking properties. They rapidly absorb sweat from the skin's surface and diffuse it across the fabric, expanding the evaporation area. This process utilizes the latent heat exchange principle of evaporation to remove a significant amount of heat, thereby achieving a cooling effect.

Minerals or Special Additives: During the fiber production process, mineral powders with excellent thermal conductivity (such as jade powder) or special chemicals (such as xylitol) may be added. These ingredients accelerate heat conduction and dissipation, allowing the fabric to dissipate heat more quickly when in contact with the skin.

Finishing Technology: Through specialized finishing processes, such as the use of cooling agents, a coating or microcapsules are added to the surface of the fabric that absorbs and quickly releases heat, without altering the original fabric properties. This creates an instant cooling sensation while maintaining excellent washability.

Physically or chemically modified fibers: Existing fibers are modified using physical or chemical methods to enhance thermal conductivity and moisture absorption, or new synthetic fibers with inherent cooling properties are used.
