・What is SOLFIBER? It generates heat by absorbing far infrared rays such as transmitted sunlight and body heat. The radiant heat creates a heat circulation/heat cycle.
・Uses [core-sheath composite fiber technology]: By incorporating high-density conductive heat generating carbon particles into the core, semi-permanent performance is ensured. Produces high thermal efficiency.
・[Solar heat generation]: The carbon particles kneaded into the core of the thread absorb a wide range of wavelengths of sunlight (infrared, visible, and ultraviolet). It efficiently converts into heat and warms the fabric.
・[Keeps you warm with your own body temperature]: Carbon particles absorb body heat (far infrared rays) and effectively radiate far infrared rays to keep your body warm.
