Cotton is grown on cotton bushes, it is picked then run through a machine which seperates the fibres into individual strands. The strands are spun into lenghts and three lenghts are spun into one to make it stronger, it is continually made wet then dried, as cotton is strongest when wet. Then all of the lenghts are pleated together some horizontal and some vertical so they become sort of a patchwork, thus cotton material is made. It is cut into whatever shape you require.

Cotton is a soft fiber that grows around the seeds of the cotton plant (Gossypium spp.), a shrub native to the tropical and subtropical regions of both the Old World and the New World. The fiber is most often spun into thread and used to make a soft, breathable textile, which is the most widely used natural-fiber cloth in clothing today. The English name descends from the Arabic word al qutun, (whence also came the Spanish word algodón) meaning cotton fiber.

Cotton fiber (once processed to remove seeds and traces of wax, protein, etc.) consists of nearly pure cellulose, a natural polymer. Cotton production is very efficient, in the sense that, ten percent or less of the weight is lost in subsequent processing to convert the raw cotton bolls into pure fiber. The cellulose is arranged in a way that gives cotton fibers a high degree of strength, durability, and absorbency. Each fibre is made up of twenty to thirty layers of cellulose coiled in a neat series of natural springs. When the cotton boll (seed case) is opened the fibres dry into flat, twisted, ribbon-like shapes and become kinked together and interlocked. This interlocked form is ideal for spinning into a fine yarn.

Cotton is grown. The bolls of cotton are pulled into long fibers ans twisted into thread. The thread is then woven into cloth.

I suggest that rather than getting other people to do your homework that you do it youself and have a look on the web or even NO a book! It's called learning things.

Part of learning is finding things out for yourself this is why you were set this assignment. What you are doing now is CHEATING
