Atextile or cloth is a flexible woven material consisting of a network of natural or artificial fibres often referred to as thread or yarn. Yarn is produced by spinning raw fibres of wool, flax, cotton or other material to produce long strands. Textile manufacturing is a major industry. It is based in the conversion of three types of fibre into yarn, then fabric, then textiles.
Sources & Types:
Textiles can be made from many materials:
1. Animal textiles
2. Plant textiles
3. Mineral textiles
4. Synthetic textiles
Let’s discuss about processing of cotton:
Cotton is the world's most important natural fibre. There are six stages:
• Cultivating and Harvesting
• Preparatory Processes
• Spinning
• Weaving
• Finishing
• Marketing
Preparatory processes - preparation of yarn:
OPENING AND CLEANING
Cotton mills get the cotton shipped to them in large, 500 pound bales. When the cotton comes out of a bale, it is all packed together and still contains vegetable matter. The bale is broken open using a machine with large spikes. It is called an Opener.
CARDING:
Carding: The fibres are separated and then assembled into a loose strand (sliver or tow) at the conclusion of this stage.
COMBING: Combing is optional, but is used to remove the shorter fibres, creating a stronger yarn.
SPINNING- YARN MANUFACTURE: Most spinning today is done using Break or Open-end spinning.This is a technique where the staples are blown by air into a rotating drum, where they attach themselves to the tail of formed yarn that is continually being drawn out of the chamber.
WEAVING-FABRIC MANUFACTURE: The weaving process uses a loom. The length way threads are known as the warp, and the cross way threads are known as the weft.
KNITTING- FABRIC MANUFACTURE
Knitting by machine is done in two different ways; warp and weft. Finishing - processing of textiles: The grey cloth, woven cotton fabric in its loom-state, not only contains impurities, including warp size, but requires further treatment in order to develop its full textile potential.
There are different types of finishing processes Scouring Bleaching Mercerising Singeing Raising Shrinking (Sanforizing) Dyeing Printing
