Mohair is a silky fabric that is derived from the Angora goat. It has a lustre and sheen because the fibre is not scaled over like natural fibres, but is quite smooth and reflects light well.
As a fabric it has excellent insulation properties so keeps warm in the winter but conversely due to great wicking quality keeps cool in the summer.
The Angora goat is sheared twice a year so the fibre grows long. Fibre from the younger goats is quite fine and mainly used in clothing manufacturer. Mohair blends well with wool and adds an extra lustre to worsted fabrics.
