Definition
Wool fiber is the natural hair grown on sheep and is
composed of a protein substance called as keratin. The wool fibers have crimps or
curls, which create pockets and give the wool a spongy feel and create
insulation for the wearer. Wool fiber is also known as protein
fiber. Wool’s protein is known as keratin. Keratin is made up of amino-acids
joined by peptide linkages. Wool fibers are hygroscopic and the most
hydrophilic of textile fibers. The
outside surface of the fiber consists of a
series of serrated scales, which overlap each other much like the scales of
a fish. Wool is the only fiber with such serration’s which makes it possible for
the fibers to cling together and produce felt.
