Cotton is the world's most important natural fibre. In the year 2007, the global yield was 25 million tons from 35 million hectares cultivated in more than 50 countries.[1] There are five stages[2]
Cultivating and Harvesting
Preparatory Processes
Spinning- giving yarn
Weaving- giving fabrics [a]
Finishing- giving textiles industrial revolution
The textile industry grew out of the industrial revolution in the 18th Century as mass production of yarn and cloth became a mainstream industry.[7]
In 1734 in Bury, Lancashire, John Kay invented the flying shuttle — one of the first of a series of inventions associated with the cotton industry. The flying shuttle increased the width of cotton cloth and speed of production of a single weaver at a loom.[8] Resistance by workers to the perceived threat to jobs delayed the widespread introduction of this technology, even though the higher rate of production generated an increased demand for spun cotton.
Cotton is grown anywhere with long, hot dry summers with plenty of sunshine and low humidityPlanting is from September to mid November and the crop is harvested between March and June. The cotton bolls are harvested by stripper harvesters and spindle pickers, that remove the entire boll from the plant. ginning The seed cotton goes in to a Cotton gin. The cotton gin separates seeds and removes the "trash" (dirt, stems and leaves) from the fibre. In a saw gin, circular saws grab the fibre and pull it through a grating that is too narrow for the seeds to pass. The ginned cotton fibre, known as lint, is then compressed into bales which are about 1.5 m tall and weigh almost 220 kg. Only 33% of the crop is usable lint When the cotton comes out of
