Polyester fiber – polyester fibers are synthetic fibers obtained either by melt spinning of polyethylene terephthalate (PET), the so-called virginpolyester fiber; or by recycling PET waste (plastic bottle - recycling). The use of PET waste makes it possible to reduce the cost of the fiber, whilemaintaining the required quality.
Polyester fibers have a leading position among chemical fibers. The rapid growth in the production and consumption of polyester fibers is explained bytheir versatility and high levels of physical and mechanical properties, which ensure their successful use in the production of textile products, both forgeneral consumption and for technical purposes. Polyester fibers are the cheapest synthetic fibers. Polyester fiber is successfully processed in mixtureswith natural fibers (cotton, linen, wool), also with viscose fiber.
The demand for polyester fibers is growing at a faster pace, because due to their properties they are alternative in many areas of consumption and aregradually replacing other types of fibers, both in textile and in other areas of application. As a result, their share in world fiber consumption isincreasing.
Polyester fiber can be produced with the following special properties:
