Abstract
Nowadays, many major fashion brands are now producing recycled polyester (r-PET) textile products from PET bottles to contribute to sustainability. Of course, this means that textiles containing r-PET will now be produced at an increasing volume. R-PET fiber nowadays can be produced by optimizing machine settings only in the ring and rotor spinning systems. In this study, it is aimed to investigate the spinnability of r-PET fiber in the vortex spinning system. In this context, recycled r-PET fiber from PET bottle was blended with cotton (Co) and viscose (Cv) fibers in different blending ratios and yarns production were performed in ring and vortex spinning systems. Strength, elongation, unevenness (CVm%), imperfection index (IPI) and hairiness properties were determined and the results were statistically analyzed. In addition, it was determined that yarn production method, yarn composition and blend ratio had a significant effect on investigtated properties of the yarns.
