ClearPhotodegradation Processes and Weathering Products of Microfibers in Aquatic Environments
Researchers conducted photodegradation experiments on three common microfiber types — polyester, nylon, and acrylic — to understand how they break down in aquatic environments under light exposure. They documented changes in surface morphology, polymer structure, and chemical properties over time, finding that each fiber type followed distinct degradation pathways. The study provides important insights into the environmental fate and secondary pollution potential of textile-derived microfibers.
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.
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.
Photo aging of polyester microfiber in freshwater and seawater environments: kinetics, mechanisms, and influencing factors
UV aging of polyester (PET) microfibers accelerates faster in seawater than in freshwater, driven by reactive ions like nitrate, bromide, and chloride. This matters because faster aging in marine environments means PET microfibers — the most abundant microplastic in aquatic systems — break down more rapidly into smaller, potentially more bioavailable nanoplastic fragments in the ocean.
Aging of textile-based microfibers in both air and water environments
Researchers aged textile-based microfibers under controlled air and water environments over extended periods, characterizing changes in surface chemistry, mechanical properties, and morphology, finding that degradation pathways differed substantially between air and aquatic conditions.

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.
Impact of Artificial Ageing on Microfibre Release from Polyester Textiles
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.
Behaviour of different micro-plastics during degradation in fresh and sea waters, with focus on synthetic microfibers
This conference abstract compares how different types of microplastics, especially synthetic fibers, degrade under freshwater versus seawater conditions. Understanding degradation rates and pathways is important for predicting the environmental persistence and ultimate fate of microplastics in different aquatic ecosystems.

Researchers characterized fiber fragments released from polyester textiles during UV weathering, identifying weathering as an additional pathway for microplastic fiber generation beyond the commonly studied laundry washing mechanism.
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.

This study examined how simulated degradation affects polyester microfibers from different fabric manufacturing methods, finding that woven versus knitted structures release fibers with distinct morphologies and at different rates under UV and mechanical stress.
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.
Environmental Degradation due to Synthetic Fibres
This review chapter examines how synthetic textile fibres—nylon, polyester, rayon, and acrylic—contribute to microplastic pollution through their entire lifecycle, from manufacturing to washing. Because these fibres shed millions of microfibre particles into waterways with every laundry cycle and persist indefinitely in the environment, the global textile industry is identified as a major, ongoing source of plastic contamination.
Pure Hydrolysis of Polyamides: A Comparative Study
This study examined the hydrolytic degradation of different polyamide (nylon) types under various environmental conditions. Understanding how nylon degrades is relevant to microplastics research, as nylon fishing gear and synthetic textiles are significant sources of microplastic fibers in aquatic 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.

This review examines how UV radiation drives polymer fragmentation in aquatic environments through autocatalytic thermal oxidation initiated by solar radiation, which combined with wind and mechanical stress causes molecular chain scission. The authors also discuss how prior UV aging accelerates subsequent mechanical fragmentation, providing a mechanistic framework for understanding microplastic generation from larger plastic items in water.
Accelerated Hydrolysis Method for Producing Partially Degraded Polyester Microplastic Fiber Reference Materials
An accelerated hydrolysis method was developed to produce partially degraded polyester microplastic fibers that more closely resemble environmentally weathered materials than pristine reference microplastics used in most toxicity studies. The approach allows researchers to test realistic, aged microplastic fibers from textiles, which dominate environmental microplastic contamination.

Formation of nanoparticles during accelerated UV degradation of fleece polyester textiles
Researchers investigated how UV degradation of fleece polyester textiles releases nanoparticles, finding that sunlight exposure generates significant quantities of nanoscale plastic particles. Both laboratory-simulated and real-world weathering conditions produced nanoparticle release, with particle counts increasing over time. The findings suggest that textile degradation from sun exposure, not just washing, is an important but overlooked source of nanoplastic pollution.
