Thermal and heating yarns, also called thermo generating yarns, far infrared yarns.

a. Yarn Features:

1. Heating

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.

2. Thermal

WooFit-Poly fiber has hollow structure, which can contain isolated air, maintain body temperature and isolate cold air outside.

3. Light

Hollow structure makes fiber weight very light, can make human body exercise freely.

b. Available Yarn Count:

1. Spun Yarn:

Count: 10s – 80s,

Ratio: 100% WooFit-Poly or blended with other materials,

Core spun yarn also available.

2. Filament:

50D/72F, 75D/72F, 100D/144F, 150D/144F.
