ClearMicroencapsulation for Functional Textile Coatings with Emphasis on Biodegradability—A Systematic Review
This systematic review found that microencapsulation techniques for functional textile coatings are well-established for conventional shell materials, but biodegradable alternatives remain limited and often sacrifice durability. The review identified that most microcapsule shell materials are synthetic polymers that can contribute to microplastic pollution when they degrade from textile surfaces during washing. Developing truly biodegradable microcapsule formulations is essential for reducing the microplastic fiber shedding that makes textiles one of the largest sources of microplastic pollution.
Water-Borne Polyurethane Based Composites and Their Applications in Functional Textile Coatings
This review covers water-borne polyurethane composites and their applications in textile coatings, including how different reinforcing materials affect performance. Polyurethane coatings on textiles are a significant but often overlooked source of microplastic fibers released into waterways during washing.
Integration of Advanced Biodegradable Polymer Coatings with Solar-Powered Textile Waste Treatment for Reducing Microplastic Pollution in Urban Runoff Systems
Researchers developed a prototype integrating biodegradable polymer coatings (PLA and PHA) with a solar-powered treatment unit to filter microplastics from textile-contaminated urban runoff. The system demonstrated effective filtration while producing minimal secondary pollution, offering an off-grid, low-energy solution for removing textile-derived MPs from stormwater before they reach aquatic ecosystems.
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.
Fully bio-based polyurethane coating for environmentally friendly controlled release fertilizer: Construction, degradation mechanism and effect on plant growth
Researchers developed a fully bio-based polyurethane coating for controlled-release fertilizers using castor oil and a plant-derived chemical. Unlike conventional polyurethane coatings that persist in soil as microplastics, this coating showed strong biodegradability while still effectively controlling nutrient release. The study offers a practical solution to reduce microplastic accumulation in agricultural soils from fertilizer coatings.
Long-term localization experiments reveal aging degradation mechanisms of biobased and petroleum-based polyurethanes in natural environments: degradation characteristics, product assessment and degradation cycle prediction
Researchers conducted a 807-day field localisation experiment to study the degradation mechanisms of biobased and petroleum-based polyurethanes used as polymer coatings on controlled-release fertilisers in natural soil environments. The study characterised the degradation products, assessed environmental risk, and developed a predictive model for the degradation cycle, finding that both polyurethane types fragment into microplastic residues at different rates.
Sürdürülebilir Yaklaşımlara Bir Örnek Olarak Biyobozunur Özellik Kazandırılmış Polyester İpliklerle Çevre Dostu Perde Kumaşlarının Geliştirilmesi
This Turkish-language textile study describes the development of biodegradable polyester curtain fabrics as a sustainable alternative to conventional synthetic textiles. Developing textiles that biodegrade rather than releasing persistent synthetic microfibers is directly relevant to reducing microplastic pollution from laundry.
Rapid biodegradation of microplastics generated from bio-based thermoplastic polyurethane
Researchers created microplastic particles from a plant-based, biodegradable plastic (thermoplastic polyurethane) and showed that bacteria could break them down rapidly, using the plastic as their sole food source. They also demonstrated that products made from this material, including coated fabric and a phone case, visibly degraded when exposed to soil bacteria. This work suggests that switching to biodegradable plastics could help reduce the buildup of persistent microplastics in the environment.
Synthesis of a new biocomposite for fertiliser coating: assessment of biodegradability and thermal stability
Researchers created a new biodegradable composite material combining cellulose nanoparticles, natural rubber, and polylactic acid, finding it would fully break down in soil within about 3,000 hours while being more heat-resistant than standard polylactic acid alone. This type of biodegradable material could replace conventional plastic coatings in agriculture, helping reduce the microplastic pollution caused by plastic mulches and fertilizer coatings.
Liquidlike, Low‐Friction Polymer Brushes for Microfibre Release Prevention from Textiles
Researchers developed a polymer brush coating strategy that practically eliminates microfiber release from synthetic textiles during washing. The study demonstrates that applying liquid-like, low-friction coatings to fibers significantly reduces the mechanical abrasion that causes millions of microplastic fibers to shed into wastewater.
Releases of microplastics and chemicals from nonwoven polyester fabric-based polyurethane synthetic leather by photoaging
Researchers compared microplastic fiber release and chemical transformation from polyurethane-coated synthetic leather and uncoated nonwoven PET fabric under UV photoaging, finding that the PU coating reduced fiber release but increased the degree of chemical oxidation. Photoaging of synthetic leather products produces microplastic fibers and chemical breakdown products that enter aquatic environments.

This review argues that synthetic textile fibers are a major source of microplastic pollution and that a shift to biodegradable fabrics represents both an environmental necessity and an opportunity to fundamentally redesign how clothing is produced and consumed.
Design of Chitosan-Polyester Composites to Reduce Particulate Contamination of Washing Wastewater
Researchers modified polyester fabrics with chitosan biopolymer coatings to reduce the amount of microplastic fibers shed during washing. Chitosan-treated fabrics released significantly fewer fiber particles, offering a practical approach to reducing microplastic pollution from laundry — a major source of aquatic microfiber contamination.
Understanding visible light and microbe-driven degradation mechanisms of polyurethane plastics: Pathways, property changes, and product analysis
Researchers found that polyurethane plastics break down in water through a combination of microbial action and light exposure, producing secondary microplastics as they degrade. This study reveals a previously underappreciated source of microplastic pollution, since polyurethane is widely used in coatings, foams, and other products that often end up in waterways.

Enhancing environmmental biodegradation of polyesters
Researchers investigated strategies to enhance the environmental biodegradation of polyester-based packaging polymers, proposing two pathways: a smart material design concept that incorporates degradation-facilitating additives, and an enzymatic approach using engineered polyesterases. The work addresses the practical challenge that biodegradable polyesters degrade too slowly under real environmental conditions, generating persistent microplastic fragments, and aims to close this gap between certified biodegradability and actual environmental breakdown.
Degradable Polymeric Waxes for Paper Coating Applications
Scientists created degradable wax-like polymers that can coat paper packaging to make it water- and oil-resistant, offering an alternative to traditional plastic coatings.

Environmental Impact of Textile Materials: Challenges in Fiber–Dye Chemistry and Implication of Microbial Biodegradation
This review examines how the textile industry contributes to environmental pollution through both chemical dye waste and microplastic fiber release. Synthetic fabrics like polyester and nylon shed non-biodegradable microfibers during manufacturing and washing, while the dyeing process generates contaminated wastewater. The paper highlights microbial biodegradation as a promising and cost-effective approach to breaking down both textile waste and the microplastics it produces.
