Thermal and heating yarns, also called thermo generating yarns, far infrared yarns.
Nano-sized coffee charcoal is put in WooFit-Poly fiber, so fabrics with WooFit-Poly yarns can release far infrared rays to generate heat to body, expanding capillaries to improve blood circulation and accelerating metabolism.
WooFit-Poly fiber has hollow structure, which can contain isolated air, maintain body temperature and isolate cold air outside.
Hollow structure makes fiber weight very light, can make human body exercise freely.
Count: 10s – 80s,
Ratio: 100% WooFit-Poly or blended with other materials,
Core spun yarn also available.
50D/72F, 75D/72F, 100D/144F, 150D/144F.
