Polyester is a category of polymers that mainly comprises of Polyethylene Terephthalate (PET). Polyester is a synthetic polymer made from PTA and MEG. Polyester Yarn is the main products in the polyester category. Almost 40% of the world production of polyester is directly used to make Polyester Yarn.
Polyester yarn is made by direct spinning of PTA & MEG. It also made by spinning PET Chips which is also a bi product made from PTA & MEG. Some of the world’s largest PTA products are British Petroleum, Reliance, Sinopec, SK-Chemicals, Mitsui and Eastman Chemicals. MEG production is in the hand of about 10 global players which are headed by MEGlobal a JV of DOW and PIC Kuwait followed by Sabic.
The main use of Polyester has been in the Textiles field for making Polyester Yarns. Polyester in different forms is used widely in textile application to make polyester (PET) resin and Filament Yarn such as Partially Oriented Yarn (POY),Polyester Drawn Textured Yarn (DTY), Polyester Fully Drawn Yarn (FDY), Polyester Staple Fiber (PSF), Polyester Spun Yarn (PSY), Technical Yarn, Tire cord and Mono filaments Yarn. Polyester yarn is also used in making packing application like polyester film, insulation tapes, strapping and several other daily use items. Polyester filament yarns is used in knitting & weaving to make polyester fabrics such as consumer fabrics and home furnishing like curtains, bed sheets, bed spreads and draperies. Similarly Polyester high tenacity industrial yarns can be used to make ropes, conveyor belts, safety belts & tire fabric. Polyester Staple Fiber is mainly used as fiber fills to stuff pillows, cushion, sofa & beddings. For the International business likes imports & export, we have strong network in China, Taiwan, Korea, Malaysia, Thailand, Indonesia, Mexico, Spain, Italy & various other countries for Polyester Yarns & Its sub-products. We have consistent monitoring of markets & providing valuable feedback to our valuable customers.
POY yarn is available in different lustre like Semi-Dull POY and Bright POY. The Bright POY has the shine in it due to the cross-sections in the filaments. The fabric made from Bright POY also has the bright lustre. Polyester POY yarn is mainly available in Raw White color & is also available in various different colors. POY is usually colored by the Dope Dyed technology as it is more efficient & the yarn gets evenly colored at each & every part. Color master-batch is mixed with the raw material to make the dope dyed POY. Dope dyed POY yarn can be used to make the Dope Dyed DTY yarn.
Polyester DTY yarn can also be obtained in various colors by the dope dyed technology or by conventional dyeing. Dope dyed DTY is usually packed on paper bobbins whereas Raw White DTY that will be used for dyeing is loosely packed on perforated plastic tube so that all the yarn can be easily dyed when the bobbin is dipped in color. DTY is mainly produced in large quantity in China, India and Taiwan and is exported world-wide.
