POLYESTER Raw (FDY- Fully Drawn Yarn): It is a fully drawn flat yarn. POLYESTER TEXTURED YARN (DTY): It is a yarn with twist vitality or elastic feature obtained by false twisting after certain processes.
POLYESTER Rope –> T.P.A (Terephthalic Acid) + TiO2 (Aqueous Titan Dioxide) + CH2OH-CH2OH (Ethylene Glycol) + H3PO4 /400 gr. (Phosphoric Acid) + Catalysis} Chips are mixed with all these acids and then cut into threads.
It is a synthetic (fully artificial) yarn type produced from polyester fiber. Petroleum-derived polyester yarns can be produced as filaments or by spinning from staple fiber. Filament yarns have a smooth, slippery surface. Their sections are round. It has high strength. The strength of the staple form is close to the filament form. Polyester yarns with high stretching properties absorb low moisture. Its melting point is 260 °C. Its ability to be thermofixed is very good. Therefore, it is very easily texturized. Polyester threads, which can be used with or without texture, are synthetic threads that have an important place in textiles.
