- A manufactured fiber in which the fiber forming substance is any long chain synthetic polymer composed of at least 85% by weight of an ester of a substituted aromatic carboxylic acid, including but not restricted to substituted terephthalic units and parasubstituted hydroxy-benzoate units. they are high is strength and are resistant to shrinking and stretching.
- A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of an ester of dihydric alcohol and terephthalic acid (ftc definition). the polymer is produced by the reaction of ethylene glycol and terephthalic acid or its derivatives. fiber forms produced are filament, staple, and tow. the process of production resembles that of nylon. polymerization is accomplished at a high temperature, using a vacuum by one of two methods. (1) the glycol and a terephthalate ester react to form a polymer chain, releasing methanol; or
