Frequently Asked Questions |
Fibre is a thread-like structure that is spun into ropes, clothes, and strings.
There are two types of fibres – One is natural fibres which are obtained from natural sources, and other is synthetic fibres which are man-made.
The fibres which are obtained from plants and animals are called natural fibres. Examples: cotton, jute, silk, wool.
The fibre which is synthesized in the industry from simple chemicals obtained from petroleum is called synthetic fibre. Examples: Nylon, Acrylic, Polyester.
Wool is the textile fibre obtained from sheep and other animals.
Rearing: It is a breeding process, feeding, and providing medical care to sheep. These animals are kept since they produce valuable products for human beings.
Breeding: Some particular breeds of sheep are specially chosen to give birth to sheep which have only soft under hair. This process of selecting parents for obtaining special characters in their offspring is termed ‘selective breeding.’
The skin of the sheep is hairy, having two types of fibres forming its fleece:
(i) the coarse beard hair
(ii) the fine soft under-hair near the skin is the fleece.
This fleece is the primary source of fibres of wool.
Making fibre into wool follows a series of processes: Shearing, → Scouring → Sorting → Dyeing → Straightening, Rolling, and Combing.
Occupational HazardsSometimes the sorters get infected by a bacterium, anthrax, which causes a fatal blood disease called sorter’s disease.
Silk is a natural protein fibre obtained from silkworm and can be used as a textile fibre.
