Fibre To Fabric

- Fibres: There are two types of fibres:
(a) Natural Fibres: The fibres which are obtained from plants and animals. Example: cotton, jute, silk and wool.
(b) Synthetic Fibres: Man-made fibres which are not obtrained from plant and animals sources. Examples: rayon, nulon, polyester, etc.

- Fibres from plant sources:
(a) Cotton: cotton is grown in black soil and warm climate.
(b) Jute: jute is obtained from stem of jute plant.

- Fibres from animal sources:
(a) Wool: wool cloth is spun from yarn made from the fibres of the thick fleece of sheep.
(b) Silk: silk thread is obtained from the saliva of an insect called silkworm.

- Processing of wool: It involves four steps:
(a) Shearing: The process of removal of wool from the sheep’s skin.
(b) Grading: The process of separating fleece from damaged wool.
(c) Carding: The process after the wool has been washed and dried, it is passed through the rollers (that have teeth).
(d) Spinning: The process by which fibrs are gathered together and drawn into a long rope and then twisted to make yarn.

- Fabrics are made from yarns, which in turn are made from fibres.

- Making Fabric from Yarn: It is done by two processes:
(a) Weaving: The process by two sets of yarns are arranged together to form fabric. It is done on looms.
(b) Knitting: The process by which a single yarn is used to make fabric. It is done by hand or machines.
