It is the abbreviation of polyester, which is a type of artificial fiber used in textiles.
Polyester is a category of polymers, or more specifically, condensation polymers containing ester functional groups within their main bonds. Although polyesters are found in nature, polyester generally refers to a large family of synthetic polyesters that includes all polyethylene terephthalate and polycarbonate.
The word polyester refers to a fabric that is usually made of polyester fiber. Polyester fibers are often combined with cotton fibers to produce garments with better properties. Polyester fabric has found a wide area of use in textiles. From polyester yarn can be used alone or mixed with other fibers to produce various fabrics such as taffeta, organza and satin are produced.
Polyester fibers, which are mostly mixed with cotton fiber, can also be used with wool, acrylic, silk, viscose and linen fibers. Polyester fibers, which are the most widely used synthetic fibers today, are easy to obtain and have a structure close to natural fibers. As an artificial fiber having a nature closest properties to cotton, polyester fibers have come to the fore with the increasing need for cotton.
Polyester obtained as a result of the condensation of a dialkol and dicarboxylic acid, is examined in 3 groups in terms of its chemical structure:
- Group 1: PET fibers (polyethylene terephthalate)
- Group 2: PCDT fibers (polycyclohexyl dimethylene terephthalate)
- Group 3: Modified polyester fibers.
