Effect of Recycled PET Fibers on the Performance Properties of Knitted Fabrics

Abstract

PET (polyethylene terephthalate) is mostly used in textile and packaging industries. PET Bottle wastes are separated from other wastes and after that some processes are applied to obtain PET flakes, such as breaking, washing, drying and etc. r-PET fibers are produced by melt spinning method from these recycled PET flakes. r-PET fibers have already been used for secondary textile products like as carpet bottoms, sleeping bags and insulation materials. In this study usability of recycled PET fibers in apparel industry were researched. Comparative investigations of bursting strength, abrasion resistance, air permeability, surface friction, circular bending rigidity and dimensional stability properties were done to knitted fabrics produced from r-PET and blends with PET and cotton fibers. It was found that, instead of PET, r-PET fibers can be blended in certain amounts without compromising fabrics performance.

A United Nations’ Sustainable Development Goals perspective for sustainable textile and apparel supply chain management

“…The authors show that the fabric made of 80%-polyester/20%- recycled-polyester presents the best properties for maintenance and durability. Telli and Özdil (2015) examine the properties of knitted fabrics made of recycled PET fibres and find that “r-PET fabrics” are cost-saving and eco-friendly, and the producers may benefit a lot from the wide use of “r-PET fibres”. Choi et al (2018a) explore the used apparel product collection in intimate apparel.…”

The effect of recycled fibers on the washing performance of denim fabrics

“…The negative features of yarns (Halimi, Hassen, Azzouz, & Sakli, 2007;Hasani, Semnani, & Tabatabei, 2010;Telli & Özdil, 2013) and fabrics (Gun, Akturk, Macit, & Alan, 2014;Necef, Seventekin, & Pamuk, 2013;Telli & Özdil, 2015) produced from recycled fibers have been discussed in previous studies. It was known from these researches that recycled yarn has lower tensile strength, higher unevenness, and higher IPI values.…”

Determination of the residence-time distribution in industrial dryer for the production of recycled polyester

“…Polyester (PES) fibers are polymers with identical chemical structure to polyethylene terephthalate (PET) and have several applications in the textile industry. Given the similarity between the physicochemical properties of PES and PET, it becomes possible to transform the recycled PET materials into PES [1][2][3]. Initially, the PET bottles are decontaminated and reduced to the granulometry of flakes.…”
