Polyester fiber

Polyester fibers are synthetic fibers, due to their low price and excellent mechanical properties they have the highest production and consumption rate between natural and synthetic fibers. These fibers have a high wrinkle, abrasion, and heat resistance along with a low water absorbency, therefore they are easy to wash and wear but have low comfort. Polyester fibers are used in the form of filament and staple fibers, they are used solely or in combination with other fibers. Polyester fibers are mainly combined with hydrophilic fibers in order to achieve goods at an economical price point with high comfort and good mechanical properties. Due to polyester’s mechanical and chemical strength these fibers are used in a vast range of applications from tents and umbrellas to scarfs and uniforms. Polyester fibers are spun through melt spinning process which enables to fabricate fibers in different shapes and sizes for specific applications. Staple polyester fibers are mainly spun through ring spinning method. Polyester microfibers are very fine fibers with cross sectional diameter smaller than 10 micrometers. The fineness of these fibers resembles silk fibers in their appearance and have a delicate hand feel and drape, but dyeing of these fibers to dark shades are problematic.
