Blankets are used to provide insulation / protection against loss of body temperature, according to the requirements imposed by climate / temperature conditions.
The mixed fibre blankets are made from second hand clothes’ various fibres. New fibres may be included as well.
The insulation capacity of a blanket depends of the thermal resistance (Rct) and of the air permeability of the material. The thermal resistance does not depend only on the weight or the raw material, but also on the fibre quality, the type of weaving or knitting, and fibre raising.
