The Hong Kong Polytechnic University (PolyU) School of Fashion and Textiles researchers have unveiled iActive, a state-of-the-art collection of sweat-wicking sportswear. When drenched, the iActive range of materials evaporates sweat three times quicker than the maximum pace at which the human body can perspire.
With its liquid transport system and “skin-like” sweat dissipator, the iActive collection ensures rapid sweat evacuation, which reduces weight and stickiness during exercise. The sportswear, which draws inspiration from the body’s natural cooling process, effectively transfers liquid from within the garment to the outside using low-voltage-powered “sweat glands” and a branching liquid transport system modeled after roots.
Under the direction of Dr. Shou Dahua, the research team has also created Omni-Cool-Dry, a fabric that offers incredibly quick sweat absorption and passive cooling by reflecting sun radiation. The fabric was inspired by insects that live in volcanoes. In addition to addressing worldwide issues with heatstroke prevention and cooling techniques brought on by extreme weather and high temperatures, both ideas seek to improve cooling sportswear.
