Why do we use 100% Cotton?
Cotton fiber is one of the most economically important nonfood plant commodities on the market, and cottonseed oil, another product of the cotton plant, is the second most important seed-oil crop.
Cotton is a natural vegetable fibre produced in many countries of the world. It is made from the soft, fluffy substance that is around the seeds of the cotton plant (Gossypium) which is almost pure cellulose. Cotton fabrics are hard wearing and capable of infinite verity of weave and coloring. As additional benefits, each cotton plant produces a large amount of fiber, and cotton costs less to process than other plant fibers.
It is used in the production of various garments such as shirts, t-shirts, dresses, towels, robes, underwear, etc. It is more suitable to manufacture light and casual indoor and outdoor wear. Cotton is also sometimes used for uniforms. In addition to the textile industry, cotton is used in fishing nets, coffee filters, tents, explosive manufacture, cotton paper and in bookbinding. It was also used previously to make fire hoses.
Cotton is composed of the polymer cellulose the basic structural component in cell walls in plants. Cellulose is made of repeat units of the monomer glucose. This is the same glucose which your body metabolizes in order to live, but you can't digest it in the form of cellulose.
Cotton is comfortable and breathable. It will draw sweat away from the body so one doesn’t get a wet, clammy feel. Moisture vapor is free to transfer through the fiber to lower the humidity between the fabric and the body, which gives a fresher cool feeling. The fibres have a lumen, a hollow opening that runs the length of the fibre, when the boll (the rounded seed capsule of a plant) opens and the fibre dries out the lumen collapses causing the fibre to twist in on itself.
Nature coats the fibres with waxes to protect it from rain when the bolls open making the cotton naturally hydrophobic (water repelling). Cotton however is known for it absorpbancy which means it must be wet-processed to remove the waxes.
To make the cotton fibres usable the seeds and fibres need to be seperated. This was previously done manually. Now a cotton gin is used, it is a machine used to quickly and efficiently seperate cotton fibres from their seeds. This enables greater productivty than manual cotton separation.
