★What is SOLFIBER? It generates heat by absorbing far-infrared rays such as transmitted sunlight and body heat.
The radiant heat creates 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).
Efficiently converts into heat and warms the fabric.
