Polyester fiber
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.
Basic properties:
- Resistant to light weather, solvents, microorganisms, moths, mold, carpet bugs.
- Low thermal conductivity and high elasticity, which makes it possible to obtain products from them that retain their shape well.
- Abrasion resistance.
- The tensile strength of polyester fibers is higher than other types of chemical fibers.
- With a higher tensile strength than natural fibers, polyester fibers are much lighter, the level of water absorption is much lower.
- Resistance to organic solvents.
- Good heat resistance - Polyester fibers are superior in heat resistance to most natural and chemical fibers.
Application of polyester fibers:
- Production of insulation materials for sewing products. The most well-known materials are sintepon and hollofan, which have excellent heat-shielding properties, voluminous, elastic. They are used as insulation pads in jackets, coats, as well as in the manufacture of quilts and bedspreads.
- Production of fillers for furniture, pillows, blankets, children's toys, etc.
- Production of sewing threads.
- Geotextile materials that are used as drainage and anti-erosion structures in the construction of highways, railways, gas and oil pipelines, as well as foundations and roofs.
- Production of fabrics used for tailoring according to state orders, including for the Ministry of Defense, the Ministry of Emergency Situations, the Ministry of Railways, etc.
- Production of special types of paper. Paper for "securities and banknotes".
- The basis for linoleum.
- Canvases for the automotive industry (floor, ceiling, car trim, sound insulation).
- Filter materials (for the oil, dairy, and food industries).
- Abrasive and cleaning materials.
- Hygienic products.
- Building materials (insulation, roofing and sound insulation materials).
