Kelheim launches new viscose fibre with IR-reflection properties
05/11/2014
Thermal radiation emanating from the body of a person wearing clothing containing the new fibre will be reflected by particles incorporated in the viscose and sent back to the body, reducing any decrease in temperature and in comfort.
“The human body, like any other matter with comparable temperature, releases a large part of its energy via thermal radiation,” Kelheim explained on announcing the new product. “This radiation is mainly composed of infrared light. It leads to a loss of energy and therefore to a cooling of the human body.”
Mineral IR-reflecting particles are incorporated into the fibre’s core, the company continued, preserving typical properties such as comfort, softness and skin friendliness. The effect is permanent as the additives cannot be washed out.
First test results of the new fibres that have already been successfully manufactured on a pilot scale, show significant temperature effects in comparison to a standard viscose fibre, Kelheim said, adding that possible applications it envisages include functional sportswear, in which the new fibre can lead to improved performance and a faster regeneration of the athlete, thanks to improved blood circulation.
