What are the components of cool feeling fabric?

Cooling fabrics are a new type of textile material that is treated through special processes or by adding specific components, enabling the fabric to quickly dissipate heat, accelerate sweat evaporation, and provide cooling functions. Here are some main components and processing methods of cooling fabrics:
1. Physical blending method
This processing method typically involves mixing high molecular polymer masterbatches with mineral powders that have good thermal conductivity, and then using conventional spinning processes to produce cooling mineral fibers. Common cooling mineral fibers include mica fiber, jade powder fiber, pearl powder fiber, etc. Among them, mica fiber is more common due to its stable chemical properties, good thermal conductivity, moisture absorption, and insulation.
2. Adding xylitol
Another method is to add food-grade xylitol to the fiber spinning solution, which can be evenly distributed on the fibers after spinning. Tests using infrared temperature measuring instruments on the temperature rise of fibers under skin heat sources found that fibers with added xylitol absorb heat more quickly.
3. Special-shaped cross-section fibers
By changing the design of the fiber cross-section, such as using melt spinning methods to obtain Y-shaped, cross-shaped, and other special-shaped fibers, these groove structures help improve capillary action and, through the design of the fiber cross-section, create a "capillary effect" that enhances the heat dissipation speed.
4. Cooling agent finishing
Cooling finishing textiles add cooling microcapsules or xylitol cooling agents to ordinary textile fabrics through conventional methods such as dipping, padding, or coating, giving them an instant cooling function. The processing technology of cooling microcapsules mainly involves refining new materials with cooling functions into liquid or solid capsules, and then using these microdroplets or particles as cores, allowing polymer film-forming materials to deposit on them, coating and forming a thin film that encapsulates the functional materials.
5. Polyester and nylon
Cooling fabrics also include polyester cooling fabrics and nylon cooling fabrics, which regulate temperature by absorbing heat, providing a cool and comfortable feeling.
In summary, the components and processing methods of cooling fabrics are diverse, aiming to achieve rapid heat dissipation and cooling effects through different means to enhance the comfort experience of the wearer.
