Where Cotton and Polyester are Made.

• Cotton comes from a cotton farm.

• Polyester is a synthetic fibre made from coal, air, water, and petroleum. It was developed in a 20th-century laboratory.

• Polyester is used in the manufacture of many products, including clothing, home furnishings, industrial fabrics, computer and recording tapes, and electrical insulation.

How the material is constructedPolyesterPolyester

• Polyester is made by reacting ter-e-ph-tha-lic acid, a petroleum derivative, with eth-y-lene glycol, another petroleum derivative (commonly known as antifreeze). When the two chemicals are combined at a very high temperature, they form a new chemical known as a polymer/polyester.

• As the above mixture cools it turns into a thick syrup. The syrup has to be forced through little holes in a machine called a spinneret as soon as the syrup has contact with air it hardens and becomes long, giant threads.

How the material is constructedCottonCotton

• The process of making cotton fabric has become a machine-made one, especially in developed countries. After harvesting, raw cotton goes through a cleaning and refining process, then it is spun into thread and woven into cotton fabric on machines called looms.
