Polüestrikiud

Polüestrikiud, often referred to as polyester fiber, is a synthetic fiber derived from petroleum. It belongs to the family of polymers and is characterized by its long molecular chains composed of ester groups. The most common type of polyester fiber is polyethylene terephthalate (PET).

The production of polyester fiber typically involves a process of polymerization, where monomers are reacted to form long polymer chains. These chains are then melted and extruded through spinnerets to form continuous filaments, which are subsequently drawn and processed into fibers. The resulting fibers can be manufactured in various forms, including staple fibers (short lengths) and filament yarns (continuous strands).

Polyester fibers are known for their durability, strength, and resistance to stretching and shrinking. They also possess good wrinkle resistance and are quick-drying. Furthermore, polyester exhibits resistance to many chemicals, mildew, and abrasion. Its ability to hold dye well contributes to vibrant and long-lasting colors in textiles.

Due to its desirable properties, polyester fiber finds widespread use in the textile industry. It is commonly blended with natural fibers like cotton to enhance the fabric's performance, offering a combination of comfort and durability. Applications range from apparel such as shirts, dresses, and activewear to home furnishings like curtains, upholstery, and bedding. Polyester is also utilized in industrial applications, including ropes, conveyor belts, and filtration materials. Its versatility and cost-effectiveness make it one of the most widely produced synthetic fibers globally.
