Synthetic Fibers. Fibres are fine filaments that either occurs naturally or can be synthesized. Synthetic fibres are man-made fibres produced from chemical substances and are used for making clothes and other useful things. These are made by the process of polymerization. Synthetic fibres can either be completely synthetic or semisynthetic ...
