Sources of protein fibre
Proteins are naturally occurring
compounds in the tissues of plants and animals. Protein fibres are generally occurred
as epithelial growth as hair or animal secretion, Wool is the most important
hair fibre, which makes up the fleece of domestic sheep, Some of the important
hair fibres are :
(a) Wool → from sheep
(b) Mohair → from angara goat
(c) Cashmere → from Cashmere
goat
(d) Camel hair → from camel
(e) Rabbit fur → from rabbit
(f) Horse hair → from horse
(g) Alpaca, llama → from
ilama
Another type of protein
fibre is produced from the larvae of caterpillars when the cocoons are formed. These
fibres are generally referred to as silk. Silk can be domesticated or wild. Some
of the important wild silks are tussali, endi, eri, muga and fogara.
Sources of protein
Protein can be obtained
from animal or vegetable sources, as it is the essential constituent of the
tissues of plants and animals. There are many proteins present in plants and
animals. However, there are only three proteins i.e., arachin, zein and glycinin
from vegetable sources and casein from animal sources that are commercially
exploited for fibre preparation.
