Polyester was one of the most popular fibers used in fashion in 2017, found in about 60% of garments in retail stores and equalling about 21.3 million tons of polyester fiber. [36] There was a 157% increase of polyester clothing consumption from 2000 to 2015. [36]
A study in 2023 tested some fish species and found that "about 80% of the MPs detected were fibrous in shape and were made of polyethylene (25%), polyester (20%), and polyamide (10%). Most microplastic particles observed were black (61%) or blue (27%) in color."
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.

These microplastics are frequently consumed by marine organisms at the base of the food chain, like plankton and fish larvae, which leads to a concentration of ingested plastic up the food chain. Plastics are produced with toxic chemicals, so these toxic substances enter the marine food chain, including the fish that some humans eat. [39]
List of some addition polymers and their uses Polymer Abbreviation Properties Uses Low-density polyethylene: LDPE: Chemically inert, flexible, insulator: Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six-pack rings, etc. High-density polyethylene: HDPE: Inert, thermally stable, tough and high tensile strength
Degraded plastic waste can directly affect humans through direct consumption (i.e. in tap water), indirect consumption (by eating plants and animals), and disruption of various hormonal mechanisms. [12] As of 2019, 368 million tonnes of plastic is produced each year; 51% in Asia, where China is the world's largest producer. [13]
