Abstract

Every day, millions of plastic and polyethylene terephthalate bottles are being thrown away by people. This leads not only to the reduction of landfills and increase in environmental problems but also to pollution of marine and oceans that affect the lives of many living things. Therefore, recycling of waste polyethylene terephthalate bottles with recycling technologies has great environmental importance. In this study, recycled polyester yarns obtained by recycling waste polyethylene terephthalate bottles and standard polyester yarns were used in staple forms, as well as binder and pile yarns of the chenille yarn structure. In this context, 16 different chenille yarns were produced and the production parameters such as rotor speed, spindle speed, and pile density are kept constant by selecting the appropriate values. Then, these chenille yarns were used as weft to produce upholstery fabrics. Tensile strength and elongation tests were applied to the upholstery fabrics, and the results were evaluated statistically. As a result of the tensile strength tests and statistical analyses, it is concluded that the weft breaking strength of all types of woven fabrics, which have 100% recycled polyester in the structures of chenille yarns as weft, is slightly decreased compared to other types, but this decrease is not statistically significant. The use of recycled polyester yarns in the structures of chenille yarns, which are widely used in the upholstery sector, will be beneficial in producing more sustainable and eco-friendly fabrics.

Highlights

In recent years, it is seen that environmental problems have increased and some balances have changed
The results show that the surface morphology of both polyethylene terephthalate (PET) fibers is similar, while recycled PET fibers have a higher tensile strength and greater elongation at break
The results show that use of 85% recycled polyester fiber (r-PET)/15% bicomponent PET had almost equal performance in terms of both fiber loss and carpet appearances with carpets consisting of 80% PET/20% bicomponent PET

Summary

Introduction

It is seen that environmental problems have increased and some balances have changed. Scientists attribute this to the fact that unsustainable situations are happening. As environmental problems started to threat both the environment and human health, some concepts such as sustainability and recycling have been expressed more frequently. Nowadays, both consumers and companies have become more aware of these issues. Primary recycling is the recycling of a product to its original state. Secondary recycling is the recycling of waste into a new product with
