What is the cooling effect of polyester fabric for sportswear?The cooling effect of
sportswear polyester fabrics is usually achieved by adding special cooling technology. These technologies create a cooling feel when the fabric comes into contact with sweat or moisture, helping to keep the body comfortable and cool. Here are some common cold sensing technologies and how they work:
Moisture wicking: Polyester fabrics generally have good moisture wicking properties, which can quickly absorb sweat from the body surface and drain it to the fabric surface. As sweat evaporates, it removes heat from the body's surface, creating a cooling sensation.
Phase change materials: Some sportswear fabrics use phase change material technology. This material can undergo phase change within a specific temperature range, absorb or release heat, thereby regulating body temperature and producing a cooling sensation.
Microporous structure: Some polyester fabrics are designed with a microporous structure, which allows air to flow and circulate better, enhancing the ventilation effect, thereby reducing heat accumulation and providing a cooling feeling.
Coating treatment: The surface coating or treatment of the fabric can increase the gloss and light reflectivity of the surface, reduce heat absorption and reduce heat transfer, thereby achieving a cooling effect.
Fiber structure optimization: By changing the fiber structure or textile process of the fabric, the breathability and quick-drying properties of the fabric can be enhanced, helping to remove body surface heat and produce a cool feeling.
What is phase change material technology in sportswear polyester fabrics?Phase change material technology is a technology that uses the properties of materials to absorb or release heat within a specific temperature range to regulate human body temperature. In
sportswear polyester fabrics, phase change materials are often added to the fabric in the form of microcapsules that contain a special phase change substance, such as wax or polymer.
The principle of phase change material technology is based on the phase change process of phase change materials from solid to liquid (or vice versa) at a specific temperature. This process will absorb or release a large amount of heat. Specifically, when the human body is in a higher temperature environment, the phase change material absorbs heat and changes into a liquid state, thereby reducing the body surface temperature; conversely, when the human body is in a lower temperature environment, the phase change material releases the stored heat , making the body feel warm.
In sportswear, this phase-change material technology can help regulate body temperature and provide a comfortable wearing experience. For example, during exercise, when the body temperature rises, the phase change material absorbs heat and changes into a liquid state, helping to dissipate heat and lower the body temperature to keep the body comfortable; when the exercise ends or the ambient temperature drops, the phase change material releases the stored energy. heat, providing extra warmth.
Phase change material technology can provide stable temperature regulation under different environmental conditions, improving the comfort and performance of sportswear.
