Polyester Polyester is another manufactured synthetic fibre. It is also referred to as Terylene or Terene. Polyester fibre has uniform diameter, smooth surface and rod like appearance. It can be made in any strength, length and diameter as per the requirements of the end use.
The fibre is partially transparent and lustrous. The moisture regain of polyester is very low, i.e., it does not absorb water easily. Thus, it is not very comfortable to wear in hot dry summer months. The most advantageous property of polyster is its wrinkle resistance.
It is one of the most commonly used fibre for blending with rayon, cotton and wool and, to some extent, spun silk.
