Microfiber fabrics are man-made and frequently used for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture (perspiration) away from the body; subsequent evaporation cools the wearer. Microfiber can be used to make tough, very soft fabric for clothing, often used in skirts, jackets, bathrobes, and swimwear.
In the marine environment, plastic pollution causes "Entanglement, toxicological effects via ingestion of plastics, suffocation, starvation, dispersal, and rafting of organisms, provision of new habitats, and introduction of invasive species are significant ecological effects with growing threats to biodiversity and trophic relationships.
Microfiber pollution has existed as long as the textile industry has, but only recently has it come under public scrutiny. [55] The Ocean Wise Conservation Association produced a study discussing the textile waste. For polyester, it stated that on average, humans shed around 20 to 800 mg micro polyester waste for every kg textile washed.
Washing machine manufacturers have also reviewed research into whether washing machine filters can reduce the amount of microfiber fibers that need to be treated by sewage treatment facilities. [70] These microfibers have been found to persist throughout the food chain from zooplankton to larger animals such as whales. [8]
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.

An study published in the journal Science of The Total Environment found PET accounted for 18% of microplastics in human lung tissue samples, and that there were 0.69 ± 0.84 microplastics per gram of lung tissue. [58] SAPEA have declared that such particles 'do not pose a widespread risk'. [59]
Hydrophilicity, roughness and surface charge determine the interaction of cellulose fibers with an aqueous environment. Already in 1950, the charge at the interface between cotton as the predominant cellulose fiber and an aqueous surrounding was investigated by the streaming potential method to assess the surface zeta potential .

The polymer is formed by free-radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide (DMF) or aqueous sodium thiocyanate, metering it through a multi-hole spinneret and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated ...
