It is most frequently found in clothing and fabric manufacture, as polyester’s high strength and resilience makes for long-wearing products.
Polyester is resistant to stretching and shrinking and, perhaps more importantly for industrial applications, it is resistant to abrasion and acid degradation. Polyester has a relatively high specific gravity,
meaning that it disperses well in water, and has a relatively high melting point.
Polyester fibres are also used to make yarns and ropes, fabrics for conveyor belts, seatbelts, coated fabrics, plastic reinforcements with high-energy absorption, and to reinforce car tires. Polyester fibre is used to pad out cushions , mattresses and upholstery.
