ClearImpact of Chitosan Pretreatment to Reduce Microfibers Released From Synthetic Garments During Laundering
Researchers found that pre-treating synthetic garments with chitosan—a natural biopolymer—before washing significantly reduced the number of microfibers released during laundering. Since washing synthetic clothes is one of the largest sources of microplastic pollution in waterways, chitosan treatment could be a practical way to reduce this contamination at the source.
Impact of Chitosan Pretreatment to Reduce Microfibers Released from Synthetic Garments during Laundering
This study tested whether treating synthetic garments with a chitosan (natural shellfish-derived polymer) coating before washing could reduce the number of microfibers released into wastewater. Chitosan pretreatment significantly reduced microfiber shedding from both polyester and nylon fabrics. This approach offers a practical, scalable way to reduce microfiber pollution at the source — the washing of synthetic textiles — which is one of the largest contributors to microplastic contamination in waterways.

Reducing microplastic fiber shedding from hand-washed polyester
Researchers investigated microplastic fiber shedding from hand-washed polyester fabric, addressing a gap since most prior studies focused on machine laundering despite the majority of global garment washing being done by hand. They tested coating-based mitigation strategies and found effective approaches for reducing fiber release during hand washing. The study demonstrates that hand-washing conditions and mitigation techniques deserve specific attention in efforts to reduce textile-derived microplastic pollution.

Modified polyamide fibers with low surface friction coefficient to reduce microplastics emission during domestic laundry
Researchers developed a modified polyamide fiber that sheds 60% fewer microplastic particles during washing by incorporating a silicone-based compound that lowers surface friction. The fibers maintained good physical properties including strength and water resistance, making them practical for textile manufacturing. The study offers a promising engineering approach to reducing one of the largest sources of microplastic pollution entering waterways from household laundry.
How Low-Friction Coatings Affect Microplastic Fiber Release When Laundering Coated and Uncoated Textiles Together
Researchers tested whether low-friction silicone coatings on polyester fabrics could reduce microplastic fiber release during laundering, including when coated and uncoated fabrics are washed together. They found that the coating reduced overall fiber release by up to 37%, with the effect depending on the orientation of coated versus uncoated fabrics. The study suggests that low-friction textile finishes could be a practical strategy for reducing microplastic pollution from laundry.

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.
