Polyester

The polyester is a Polymère whose macromolecular skeleton contains reasons for repetition containing the chemical function Ester.

An example of polyester is the Polyéthylène terephthalate or FART which is used to manufacture bottles for fizzy drinks or not.

The standard polyester FART textile Fiber is resulting from the esterification of terephtalic acid and ethylene glycol in the presence of a catalyst and additive.

History

Polyethylene terephthalate was patented in 1941 by two British chemists of Manchester, John Rex Whinfield and James Holding Dickson. These chemists also took part in the invention of Terylene in 1941, textile fiber mark of the group HERE (Imperial Chemical Industry), whose patents were repurchased in 1945 by the American group Dupont de Nemours. This last created then the Dacron (1950) and Mylar (1952).

In France, the polyester fiber appeared in 1954 under the mark Tergal (equivalent of the Dacron of Dupont de Nemours), created by the firm Rhodiaceta. For the Tergal little story is made of “For the third time” (for polyester ) and “Gall” (for gallicus ), it is all in all the Gallic polyester .

Use

The polyester is especially used to manufacture Fiber S Textile S synthetic, of which most known are the Tergal and the Dacron . It is the synthetic fiber most produced in the world. It accounts for 70% of synthetic fibers used in the Vêtement where they are used for the sport clothing, the bathing suits, the Tenue S.

In addition to its very widespread use in clothing, often in mixture with other fibers, in particular the Cotton, its applications diversified in the Industrie, in particular in the form of Film S in Agriculture and in the public Travaux (Géotextile S).

In substituent for the manufacture of the bands to the traditional fragile supports such as the acetate, the polyester allowed in the Années 1970 a generalization of the tape recording at the private individuals.
