Polyesters are polymers that contain ester group in its structure.

Polyesters are synthetic, man-made materials. Basic features of polyesters:

  • Non-hygroscopic – they do not absorb water
  • Stainproof – it is very difficult to stain polyester fibers with anything water-based
  • Resilient – gets back to its original shape after being deformed quickly
  • Easy to dye – you can dye polyester fibres any color you possibly want. The outcoming color is relatively lasting and resistant

Polyester is the most widespread synthetic fiber. Its production is about 70% of the world’s production of synthetic fibers. This fiber is made from polyethylene terephthalate (PET). 60% PET is manufactured for the textile industry (for comparison, only 30% is used for the bottles production).

The following four environmental issues are related to the production of the polyester. First of all, petroleum-based substances are needed for the manufacturing processes. Secondly, this production consumes large amounts of energy, and as a consequence, CO2 emissions to the atmosphere are significant. Thirdly, heavy metals are used, such as cobalt, manganese salts, sodium, bromide and titanium dioxide. Finally, as a result of this production, a lot of waste is generated, left to free decomposition, polluting the environment for many years.

Today’s polyester fabrics often can imitate natural fabrics well. Dyeability and printing is a very big advantage, which allows for an interesting and original finish, which in the case of clothing will stand out from the crowd, and in the case of, for example, bedding will magnificently beautify the appearance of the bedroom. 

Polyester is a material that has a really wide range of applications. Polyester fabric is one of the most important possibilities of using polyesters. Thanks to the use of the most modern technologies, polyester fabrics are distinguished by a great pleasure of touch and high quality.

Polyester fibers alone or in a mixture with wool, cotton or viscose fibers are used for the manufacture of fabrics for outerwear, decorative fabrics, curtains. Textured polyester fibers are used for knitwear. These fibers are also used for the production of wires replacing sections of blood vessels and for the production of technical products, e.g. ropes, cords.
