WebMay 18, 2024 · One of the most investigated chemical recycling of PET is glycolysis with diols, such as ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol, propylene glycol, dipropylene glycol [ 1 ], 1,4-butanediol [ 2 ], and polyethylene glycol [ 3 ]. Various reaction conditions were applied for PET glycolysis by DEG. Polyester fibres are widely used in the textile industry. The invention of the polyester fibre is attributed to J. R. Whinfield. It was first commercialized in the 1940s by ICI, under the brand 'Terylene'. Subsequently E. I. DuPont launched the brand 'Dacron'. As of 2024, there are many brands around the world, mostly Asian. Polyester fibres are used in fashion apparel often blended with cotton, as heat insulation layers i…
