Many things start out as fibre. Most natural fibres come from animals and
plants. A few are got from minerals. Today much fibre is produced by chemical
processes. Such fibres are classified as synthetic Silk, cotton and wool were
known to the ancient civilizations of the Middle and Far East Wool comes
mostly from sheep Woolen clothing is very warm.Silk is a thread spun by the
larva or silkwork of the Bombyxmori moth. Silk was the favourite clothing for
the rich in China, Japan and India. The cotton plant produces many large
seeds pods containing fibre clusters called bolls. Cotton fabrics are cool, so
they are suitable as clothing in hot climates. Jute is grown mainly in India and
Bangladesh. It is inexpensive to produce and the better grades are made into
wrapping materials.
Asbestos in a mineral fibre got from an inorganic source. The soft, whitish
fibre is weak and brittle, but is non-inflammable. So it is used for fire proofing
of buildings
The manufacture of rayon was the real beginning of the Synthetic fibre
industry. It was important during World War II as the material for parachutes.
Like all Synthetic fibres, nylon makes up strong textiles. It has a great ability to
recover its size and shape if crumpled. Hence it is used to make children's
women's hosiery
Acetate fibre was difficult to dye at first. It is very silky in appearance and is a
popular textile for furnishings.
