Description
Poly(ethylene terephthalate) is a colourless rigid substance. Because of its structural regularity, the polymer readily crystallizes and the physical properties of the bulk material are greatly affected by the extent of crystallinity, which, in turn, is largely determined by the previous history of the material. In the production of fibre, the molten polymer is extruded through spinnerets into air at normal temperature. The filaments are thus rapidly cooled and are largely amorphous and are weak. The filaments are then drawn at a temperature above the glass-transition temperature (80°C), whereby molecular orientation and crystallinity are induced. Finally, the filaments are heated at about 200°C under tension to give a dimensionally-stable material of maximum crystallinity. The manufacture of poly(ethylene terephthalate) film closely resembles that of fibre and also involves extrusion, orientation and stabilization.
