Polyester Plant
Polyester fibers, like other synthetic fibers, are produced industrially and are considered suitable substitutes for natural fibers such as cotton due to their properties. To make this product, a combination of dimethyl terephthalate and monoethylene glycol, or terephthalic acid (a substitute for the primary material dimethyl terephthalate), is used in the presence of suitable catalysts. The polymer resulting from the combination of these two raw materials is passed through spinnerets by a pump and, under the influence of cold air, is transformed into fibers and collectively forms a bundle of fibers. In subsequent stages, through stretching and heat treatment, while the molecular arrangement is organized and thermally stabilized, it is cut into long (filament) or short (staple) fibers in desired sizes and packaged (baled).
Currently, the polyester plant of Iran Polyacryl Company is operating with a capacity of about 36,000 tons per year. The fibers produced by this plant are produced in the polyester plant with finenesses of 1.4 and 3.3 dtex and cut lengths of 38 millimeters. This plant also has the capability to produce fibers with finenesses of 1.2 and 1.6.
Consumers of these fibers are often spinning units. After spinning the fibers, these units use them to produce warp-weft fabrics for clothing, sheets, and bedding.
Polyester fibers produced by Iran Polyacryl Company have important properties such as high strength, good recovery and dimensional stability, abrasion resistance, resistance to sunlight, and some chemicals.
