Wool, which is in the hair-based group of animal fibres and has the unique features of fineness, longness, elasticity and curling, is a highly valuable fibre that can regulate physical-chemical reactions. It provides healthy usage because of its features of keeping warmish and cool, breathability, soft and elastic structure, heat retention ability, absorbing moisture (with this characteristic it minimises perspiration.) and less wettability originating from its strong molecular structure.
