This study assessed how artificial ageing through UV exposure and repeated washing affects microfiber release from polyester textiles, finding that ageing significantly increases the number and changes the characteristics of shed microfibers.
Characterization of Nanoplastics, Fibrils, and Microplastics Released during Washing and Abrasion of Polyester Textiles
Researchers analyzed the full range of plastic particles released during washing and physical abrasion of polyester textiles, including nanoplastics smaller than 1000 nanometers. They found that both washing and abrasion produced substantial numbers of nanoplastics and microfibers, with abrasion generating even finer fragments. The study highlights synthetic clothing as a significant and underappreciated source of very small plastic particles entering the environment.
Analysis of ultraviolet and thermal degradations of four common microplastics and evidence of nanoparticle release
Researchers studied how UV light and elevated temperature break down four common plastics and found that weathering releases nanoscale plastic particles. Polystyrene and polypropylene were particularly susceptible to UV degradation, generating significant numbers of nanoparticles. The findings confirm that environmental conditions actively fragment microplastics into even smaller, potentially more harmful nanoplastics.
Physiochemical Degradation of Plastic Fibers from Synthetic Fabrics and Effect of Natural Organic Matter in Aquatic Environments on Nanoplastics’ Behavior
Researchers studied how laundry conditions affect microfiber release from synthetic fabrics and how UV irradiation and pH alter fabric degradation, then examined how natural organic matter (NOM) influences nanoplastic behavior in water. They found that degradation conditions significantly changed fiber release rates and that NOM modified nanoplastic aggregation and stability.
Simulation of accelerated ageing of polyester fabric
Researchers simulated accelerated aging of polyester textile fabrics, finding that synthetic fiber degradation — driven by fast fashion, consumerism, and environmental exposure — contributes to microplastic pollution and raises ecological concerns about the lifecycle of synthetic textiles.
Formation of microplastic fibers and fibrils during abrasion of a representative set of 12 polyester textiles
Abrasion testing of representative polyester fabrics generated microplastic fibers and fibrils, with fiber characteristics reflecting the mechanical and chemical properties of the parent textile. The findings suggest that real-life wear and abrasion during use, not just laundering, is a significant pathway for microfiber release from synthetic textiles.
Exploring the environmental impact of textile polymer photodegradation through a multianalytical approach
Researchers used a multi-analytical approach to study how photodegradation of textile polymers generates microfibers and other plastic fragments with potential ecotoxicological impacts. The study characterized degradation products and their effects on aquatic organisms, linking polymer weathering to broader environmental harm.
Microplastic fibres from synthetic textiles: Environmental degradation and additive chemical content
Researchers studied how common synthetic textile fibers — polyester, polyamide, and polyacrylonitrile — degrade in seawater and freshwater under UV light exposure. They found that these fibers release chemical additives as they break down, with polyester and polyamide releasing particularly concerning levels of plastic-related chemicals into the surrounding water.
UV degradation of natural and synthetic microfibers causes fragmentation and release of polymer degradation products and chemical additives
Researchers exposed natural and synthetic microfibers to UV radiation and found that degradation caused the fibers to fragment into smaller particles while releasing polymer breakdown products and chemical additives. Polyester and polyamide fibers showed distinct degradation patterns, with different chemicals leaching depending on polymer type. The study highlights that microfiber degradation in the environment creates secondary pollution through both physical fragmentation and chemical release.

This study examined how simulated UV and mechanical degradation affects the release and properties of polyester microfibers from differently manufactured fabrics during laundry, finding that fiber structure and manufacturing method influence fragmentation rates and fragment characteristics.
Formation of Nano- and Microplastics and Dissolved Chemicals During Photodegradation of Polyester Base Fabrics with Polyurethane Coating
Researchers investigated the photodegradation of polyester fabrics with polyurethane coating, a common composite material in synthetic leather, to understand microplastic and chemical release. The study found that the PU coating delayed but did not prevent degradation, with both microplastic fibers and particles being released along with dissolved chemicals, highlighting the environmental risks of composite plastic materials.
Characterisation of microplastic fibres and their degradation under environmental conditions
This study investigated how UV radiation and mechanical stress degrade common synthetic microfibers including polyester, nylon, and acrylic, which represent the largest fraction of microplastic pollution in aquatic environments. Understanding how fibers degrade helps predict their persistence and how their physical properties change as they age in the environment.

Disposable plastic face masks, widely used during the COVID-19 pandemic, break down under UV exposure into a heterogeneous mix of microplastics and nanoplastics that can enter water, soil, and food chains. This study used state-of-the-art analytical tools to characterize the particles released, helping quantify masks as a significant novel source of environmental plastic pollution that emerged alongside the pandemic.

Effects and Characterization of Environmental Conditions on Microplastic Fibers Release from Synthetic Textile
Researchers investigated how environmental conditions such as moist heat, high-temperature drying, and abrasion affect the release of microplastic fibers from synthetic textiles. The study found that these aging processes significantly increased fiber shedding, highlighting synthetic clothing as a major ongoing source of microplastic contamination in water environments.
A novel method for the isolation, characterisation, and quantification of nanoplastic fibres released from synthetic textiles during laundering
Researchers developed a novel method for isolating, characterising, and quantifying nanoplastic fibres (NPFs) released during laundering of synthetic textiles — including acrylic, nylon, and polyester — enabling fibre size differentiation from the micro to the nano scale. The method addresses a significant gap in textile pollution research by providing a tool to study the understudied nanoplastic fraction of laundry-derived fibre emissions.

Researchers measured microfiber shedding from a range of consumer apparel textiles during simulated laundry cycles, finding that fiber release varied substantially by fabric type, construction, and wash conditions, with polyester fleece releasing the most microfibers per wash.
Formation of Fiber Fragments during Abrasion of Polyester Textiles
Researchers investigated how physical abrasion of polyester textiles produces microplastic fibers and found that the process generates both standard-diameter fibers and much finer fibrils, some as thin as 2.4 micrometers. The number of fibrils produced during abrasion exceeded the number of regular microplastic fibers, and abrasion released 5 to 30 times more fiber fragments than washing. The study suggests that everyday wear of synthetic clothing may be a more significant source of microplastic pollution than previously recognized.

UV irradiation experiments showed that both polypropylene and PET plastics rapidly shed microplastic particles down to 1 micrometer in size when exposed to UV light in water, with recycled PET producing significantly more particles than virgin PET. This confirms that UV weathering — occurring continuously outdoors — is an active mechanism generating very small microplastics from everyday plastic products and packaging.
