PCM Phase Change PE/PP Based Bico Staple Fiber for Spinning

PCM fiber is a kind of heat storage and temperature regulation functional

fiber developed by utilizing the characteristics of releasing or absorbing latent heat and keeping the temperature unchanged in the process of material phase change.

When the ambient temperature or the temperature of human skin reaches the melting point of the phase change material in the garment, the phase change material absorbs heat and turns from solid to liquid at the same time, thereby producing a brief cooling effect on the inner layer of the garment. The heat energy may come from the warm environment outside, or from the human body itself (such as heat generated after exercise), and the energy storage ends once the phase change material is completely melted. If used in a cold environment below the crystallization temperature of the phase change material, the temperature of the garment will be lower than the phase change temperature.

At this time, the liquid phase change material will transform back to a solid state, releasing its stored energy and providing a short-term heating effect. This thermal transfer acts as a cushion within the garment, reducing changes in skin temperature and extending wearer comfort.

PCM fiber environmental adaptability technology has a wide range of applications, including underwear, outerwear, sleep bag, cushion, home wear, sportswear, complex sports (climbing, skiing, rock climbing, hiking, cycling, etc.), special occupations (military, medical, etc.) scene can be used.
