Polyester fiber is lightweight, bio-compatible, quick-drying, and versatile.

quillsPolyester is 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. This includes, but is not restricted to, substituted terephthalic units and parasubstituted hydroxy-benzoate units.

Polyester fiber properties include:
  • High strength
  • Dimensional stability and strength
  • Lightweight
  • Resistant to shrinking
  • Controlled elongation
  • Abrasion resistant
  • Mildew-resistant
  • Flexible
  • Low moisture absorption
  • Quick drying
  • Chemical resistance in specific environments
  • Bio-compatible
