yarn has a clover-like cross section which makes it
possible to absorb and evaporate body sweat rapidly
by the capilliary effect.
to the clover-like cross section, the surface area of each filament
yarn is wider than that of standard yarns and so diffuses and evaporates
the water very quickly.
Cooltec fabrics not only dry fast but due
to the speed of evaporation, they dry fast and help maintain cool body
temperature for excellent comfort.
