Wool fibre is an albumen fibre that is similar to human skin with respect to its component parts. Wool possesses excellent warmth retention, regulates cutaneous respiration and the oxygen exchange. Wool is also moisture-regulating, i.e. it can absorb up to one third of its own weight of moisture and, pending external conditions, return it to the environment.
