Polyester

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

quills Polyester 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
