Cotton textile industry

In a saw gin, circular saws grab the fiber and pull it through a grating that is too narrow for the seeds to pass. The ginned cotton fiber, known as lint, is then compressed into bales which are about 1. 5 m tall and weigh almost 220 keg. Only 33% of the crop is usable lint 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. In order to fluff up the cotton and remove the vegetable matter, the cotton is sent through a picker, or similar machines.

The cotton is fed into a machine known as a kicker, and gets beaten with a beater bar in order to loosen it up The cotton comes off of the picking machine in laps, and is then taken to carding machines. The carders mainly of one big roller with smaller ones surrounding it. All of the rollers are covered in small teeth, and as the cotton progresses further on the teeth get finer (I. E. Closer together). Combing is optional, but is used to remove the shorter fibers, creating a stronger yarn. [9] several slivers produces a very thick rope of cotton fibers, directly after being combined the slivers are separated into roving’s.

These roving’s (or clubbing) are then what are used in the spinning process. [10] The spinning machines takes the roving, thins it and twists it, creating yarn which it winds onto a bobbin. [ The weaving process uses a loom. The lengthy threads are known as the warp, and the cross way threads are known as the weft. The warp which must be strong needs to be presented to loom on a warp beam. Major changes came to the textile industry during the 20th century, with continuing technological innovations in machinery, synthetic fiber, logistics, and globalization of the business.
