What are Far-Infrared Textiles?

Far Infrared (FIR) textiles are a new category of functional textiles that have putative health and wellbeing functionality. To create far infrared-emitting fabric, bio-ceramics/thermo-reactive minerals are embedded in the fibers in one form or another (often as a powder). The principal source of energy needed to power the FIR emission from the garments comes from the human body, since it is at a significantly higher temperature than the surrounding air. So, energy from the human body is transferred to these ceramic particles, which are acting as "perfect absorbers", maintain their temperature at sufficiently high levels and then emit FIR back to the body.
