Textiles Have A Demand For The Polyester Filament Yarn


Polyester filament yarns due to their tensile capacity, yarns have been given greater demand for better textile products. Many products from fabric to socks and some home textiles.

Fabrication of polyester filament yarns begins with the manufacture of filament yarns, followed by the process of combining the polyesters. The partially oriented tow or partially oriented yarn is manufactured by winding the filament receiving cartridge at a speed slightly higher than the extrusion speed. A large number of filaments are collected to form a tow, which can then be cut into short fibers. If the fiber is used as a continuous filament yarn, the thread is wound on a metal cylinder, paper tube or spool. The diameter or fineness of spun yarn, filament yarn or monofilament, in units of Daniel, in grams of yarn or filament. Clothing and household goods yarns usually have a denier of 80 to 160.

Polyester filament yarn spinning and stretching equipment can usually be used to produce other melt-spun fibers such as nylon 6 and nylon 66, relatively small modifications. Waste polyester polymers or fibers are sold, reprocessed, burned or buried, depending primarily on purity. Next, the fibers are stretched to further orient the polymer molecules and adjust the tensile strength, elongation, modulus, dyeability and other physical properties of the fibers. The fibers are further processed by stretching, stretching-weaving, rotating stretching, crimping, winding and winding.

China, the United States and Western Europe have been major polyester importing countries in the past three years. In recent years, China's average annual imports of polyester 950,000 tons, accounting for about 10% of China's annual consumption. Similarly, the United States and Western Europe imports about 500,000 to 100,000 tons, accounting for 30% of their consumption and 40%. In the exporting countries, Taiwan and South Korea are large polyester exporters, nearly three years of exports close to 700-90 million tons. Malaysia, Thailand and Indonesia have exported about 20,000 to 300,000 tons of polyester per year over the past three years. Between 2002 and 2006, the United States also exported about 700,000 tons of polyester per year.
