NATURAL FIBRE

Natural fibre, any hairlike raw material directly obtainable from an animal, vegetable, or mineral source and convertible into nonwoven fabrics such as felt or paper or, after spinning into yarns, into woven cloth. A natural fibre may be further defined as an agglomeration of cells in which the diameter is negligible in comparison with the length. Although nature abounds in fibrous materials, especially cellulosic types such as cotton, wood, grains, and straw, only a small number can be used for textile products or other industrial purposes. Apart from economic considerations, the usefulness of a fibre for commercial purposes is determined by such properties as length, strength, pliability, elasticity, abrasion resistance, absorbency, and various surface properties.

History

The use of natural fibres for textile materials began before recorded history. The oldest indication of fibre use is probably the discovery of flax and wool fabrics at excavation sites of the Swiss lake dwellers (7th and 6th centuries BCE). Several vegetable fibres were also used by prehistoric peoples. Hemp, presumably the oldest cultivated fibre plant, originated in Southeast Asia, then spread to China, where reports of cultivation date to 4500 BCE. The art of weaving and spinning linen was already well developed in Egypt by 3400 BCE, indicating that flax was cultivated sometime before that date. Reports of the spinning of cotton in India date back to 3000 BCE. The manufacture of silk and silk products originated in the highly developed Chinese culture; the invention and development of sericulture (cultivation of silkworms for raw-silk production) and of methods to spin silk date from 2640 BCE.

SYNTHETIC FIBRE

Synthetic fibers such as glass fibers, carbon fibers, and boron fiber are gaining more attention over last two decades. Natural fiber composites are having healthy competition with synthetic composites such as glass–polypropylene and glass–epoxies. Synthetic fiber-reinforced polymer composites provide high-strength and stiffness materials that are widely accepted as aerospace components and automotive industries. Nowadays, natural fibers are used to replace synthetic fibers because of environmental concern as a reinforced material in polymer composites for engineering materials. Hybrid composites of natural and synthetic fibers are often used to enhance the mechanical strength of polymer composites.

Difference between Natural and Synthetic fibres

NATURAL FIBRES

* Comes from nature

* Natural color

* During spinning process spinneret is not necessary

* Chances of containing dust or impurities

* Less durable than synthetic

SYNTHETIC FIBRES

* Man made fibres

* Color as per requirement is added in color bath

* During spinning process spinneret is necessary for the production of     filament

* No chance of any dust or impurities

* More durable than natural
