Experimental Study on Textureability of filament yarns produced from Recycled and Bottle Grade PET.

Production of the PET has rapidly increased since its introduction on the market in 1950 s due to durability, wash-nwear properties and excellent performance [1].Texturing being a one-step process for converting flat yarns directly to crimpy yarn is ideally suited for processing several thermoplastics polymers. The process uses drawing of the fiber heater to set the fiber [2]. As false twist draw-texturing is a process that includes closeinteractions between machine working parameters and textured yarn properties. The effects of process parameters have so far been widely investigated. The most importantparameter is the yarn temperature which depends on the heater temperature and the speed of the yarn as it passes through theheating zone. The aim of this work is to investigate processing behavior of textured yarn from recycled PET(R-PET) and bottle grade PET (BG-PET) at the draw-texturing machine and compare with fiber grade PET (FG-PET) as a control
