Polyester fiber is lightweight, bio-compatible, quick-drying, and versatile.
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:
|Tenacity (g/denier)||8.8 - 9.1|
|Elongation at break (%)||13.9 - 14.3|
|Shrinkage at 177°C (%)||7.9|
|Melting point (°F)||493|
|In flame||Burns slowly; melts and drips|
|Chemical resistance||Good resistance to weak alkalis & weak acids. Moderate resistance to strong acids & alkali|
|Specific gravity (g/cc)||1.38|
|Moisture regain (%)||0.4|
