  • Polyester clothing can be machine washed and dried

Uses of Polyesters

  • Polyester film (PETF) is a semi crystalline film used in many applications such as videotape, high quality packaging, professional photographic printing, X – ray film, floppy discs
  • PET is a highly malleable material and appears in all sorts of applications, such as drink bottles, food trays and hoses
  • PET can also be used to make fibres that are used in products such as auto upholstery, quilt batting and clothing
  • Polyester clothing tends to be slippery and silky in feel
  • Fibres can be used to make clothes by knitting or weaving
