Could Dyeing Process Be Eliminated for PES/CO Fabrics Through Recycling?

As it is known, finishing processes of polyester/cotton blended fabrics require a double dyeing process. Therefore, the consumption of water, energy and chemicals and the waste it generates are quite high. Within the scope of this study, it is aimed to compare the yarn and fabric performance properties of a PES/CO blended fabric of a certain color, produced by using virgin fiber or recycled fiber in its CO component. In the light of the studies, it can be said that during the production of PES/CO blend fabric, recycle cotton can be used as well as virgin fiber, and although there won’t be problem in terms of color and fastness, the fabric produced cannot meet the standards provided by the fabric produced from 100% virgin fiber in terms of general appearance and physical-technological properties. Beyond that, the color gamut will also be limited. However, in the case of using recycled fiber, it is thought that significant environmental benefits will be achieved, both because a waste is recycled and a fabric that requires too many processing steps such as a PES/CO blend can be produced without dyeing. It is also worth noting that fabrics produced using recycle fibers have a unique visual effect. The worn-out look can be particularly interesting in some product lines.
