Cooling Fibre with Selective Near-Infrared and Visible Light Reflection

This novel synthetic reflects near-infrared (NIR) and visible light from the sun and allows the human body to release middle-infrared (MIR), achieving outstanding cooling effects under solar radiation. Inspired by Salty Ice Plant, a natural plant which holds salt crystals on the surface of leaves and stems and reflects sunlight to cool itself, we use bicomponent melt spinning to deposit ceramic crystals inside synthetic fibres with smooth layer.

Textiles made from these fibres reflect sunlight while allowing the body to release heat freely. In addition, these textiles can block the most of UV light by absorption. They can induce excellent cool feeling in the sun, which is especially helpful to workers in open places and residents in tropical areas.
