what is the process to get fabric from fribres |
Fabric are any material made through weaving, knitting, spreading, crocheting, or bonding that may be used in production of further goods (garments, etc.). Textile materials are made in three stages: spinning: fibres are spun into yarns weaving or knitting: yarns become fabrics finishing: fabrics are finished to make them more useful There are two types of textile fibres: natural fibres synthetic Natural fibres Natural fibres come from plants, animals and minerals. They usually have short fibres, called staple fibres. The exception to this is silk. Sources of natural fibres Cotton from the cotton plant. Linen from the flax plant. Wool from sheep. Silk from silkworms. Fibre Fabrics are made up of yarns and yarns are further made up of fibres. The fibres of fabrics such as cotton, jute, silk and wool are obtained from plants and animals. These are called natural fibres. Cotton and jute are obtained from plants. Wool and silk fibres are obtained from animals. Wool is obtained from the fleece of sheep or goat or from the hair of rabbits, yak and camels. Silk fibre is drawn from the cocoon of silk worm. Fibres are also made from chemical substances which are not obtained from plant or animal sources. These are called synthetic fibres. Eg :- Polyester, Nylon, Rayon Some Plant Fibres Cotton The small thin strands of cotton wool are made up of cotton fibres. Cotton plants are usually grown at places having black soil and warm climate. The fruits of the cotton plant are called cotton bolls. After maturing, the bolls burst open and the seeds covered with cotton fibres can be seen. From these bolls, cotton is usually picked by hand. Fibres are then separated from the seeds by combing and this is known as ginning of cotton. Jute Jute fibre is obtained from the stem of the jute plant. It is cultivated during the rainy season. In India, jute is mainly grown in West Bengal, Bihar and Assam. The jute plant is normally harvested when it is at flowering stage. The stems of the harvested plants are immersed in water for a few days. The stems are rot and fibres are separated by hand. |
