All synthetic fibres are man-made fibres that are prepared by a number of processes using raw material of petroleum origin, called petrochemicals. All fabrics are materials made from many fibres. Cotton, jute, wool and silk are natural fibres. Synthetic fibers are created by forcing, usually through extrusion, fiber forming materials through holes (called spinnerets) into the air, forming a thread. Before synthetic fibers were developed, artificially manufactured fibers were made from cellulose, which comes from plants. These fibers are called cellulose fibers.
All natural fibres are used for making fabrics, which are further used for making clothes. Next to food, the most important need for human beings is clothing. It is not only that clothes are a part of our moral code and decency, they also protect us from extreme temperature and climate change. Further­more, these fibres are used for making ropes, fishing nets, carpets, sails for boats, and variety of other articles of daily use.
However, the demand for fibres and fabrics is so large that natural fibres are insufficient to fulfil it. To meet this demand, scientists have developed artificial fibres, using petroleum products and coal as raw materials. These artificial fibres are commonly called synthetic fibres or man-made fibres.
