Recent Studies on Recycled PET Fibers: Production and Applications: a Review

et al. 2021

Increasing demand for non-biodegradable plastics undesirably leads to their accumulation and calls for an appropriate solution for this global crisis. Environmental impacts of PET waste have long been addressed; although some remedies have been proposed, their extensive use in the modern world use demands new studies and recycling techniques. It shows the inadequacy of previous solutions to eliminate this environmental problem. Therefore, researching this subject should not be considered an insignificant issue. Distinctively, this review article has a specific reliance on the use of recycled PET fibers in the production of high-consumption and value-added products that, in addition to considering environmental aspects, can also be attractive to the market. This article deals with recent studies in three product categories (concrete, nonwoven fabrics, yarns) made from recycled PET fibers and shows the high potential of PET fibers for the future industry.

A new method for the recycling of a polyester tire cord under the action of oligoethylene terephthalates, bis(2-hydroxyethyl) terephthalate and ethylene glycol has been proposed. The method involves simultaneous homogeneous glycolysis of polyethylene terephthalate and devulcanization of crumb rubber. Polyester cord and glycolysates were characterized by FTIR spectroscopy and gel permeation chromatography (GPC). The devulcanization process was investigated by swelling-based methods. The rate of the proposed method of homogeneous glycolysis in a melt phase was proved to be higher than one of the heterogeneous glycolysis. The assumption of a more efficient devulcanization in the presence of a softener was also confirmed. The degree of devulcanization 46.07%, the apparent degree of swelling 167.4%, and the apparent swelling rate constant 0.0902 min−1 were achieved. The results indicate that the proposed method made it possible to carry out the glycolysis of the polyester cord of the tire more deeply than the known heterogeneous glycolysis with various agents, but further research is needed for industrial implementation.
