Effects and Characterization of Environmental Conditions on Microplastic Fibers Release from Synthetic Textile

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 19, 2024

Abstract Microplastic fibers account for approximately 40–90% of the total amount microplastics in water environments and sediments. Synthetic textiles are susceptible to aging as a result prolonged exposure moist heat, high-temperature drying, abrasion, resulting release microplastic fibers. However, studies on effects environmental conditions remains limited. Herein, influence wet abrasion from six different synthetic was studied. The results demonstrate that average after undergoing wet-heat treatment, drying found be 3.7–10.5 times, 6.5–7.7 8.4–14.6 times higher, respectively, comparison standard washing procedures. number of3523-8172 per gram acrylic fabric various treatments. Additionally, quantity released polyester during first wash 5.15–37.6 greater than those fifth wash. This study provides valuable insights into mechanisms underlying textiles, well such releases. solid foundation development measures mitigate these pollutants environment.

Quantification and distribution of marine microdebris in the surface waters of Livingston Island (South Shetland Islands, Antarctica)

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 195, P. 115516 - 115516

Published: Sept. 8, 2023

Microdebris are ubiquitous and the Southern Ocean is no exception. Despite recent increment in Antarctic studies assessing this threat, there still scarce information available. Here, we quantified microdebris surface water, their distribution within two bays of Livingston Island (South Shetlands, Antarctica). The studied included one with human presence pristine, barely visited. pollution was found all samples a mean concentration 0.264 ± 0.185 items/m3. Fibres (82.19 %) were main item, polyester (61.67 as plastic polymer, followed by nylon (29.54 %). No differences pattern observed, being homogeneously distributed along bays. Our results suggest that nearshore waters prone to accumulation retention microdebris. composition also points local activities principal contamination contributors.

Impact of textile composition, structure, and treatment on microplastic release during washing: a review

Textile Research Journal, Journal Year: 2024, Volume and Issue: unknown

Published: June 20, 2024

This research critically reviewed the influence of textile characteristics, including content (fiber composition), yarn construction, material structure, and treatment type, on microplastic release from products during washing. To date, predominant focus has been washing parameters rather than intrinsic characteristics textiles. The findings this review revealed that natural, man-made, mixed-composition fabrics tend to more microfibers compared pure synthetic fabrics. Divergent results have observed in studies microplastics recycled Woven less knitted However, it is evident construction impact composition or high-twist filament yarns reduce formation. Mechanical finishes enhance release, while biodegradable it, but their sustainability durability aspects need further investigation. different types dyes remains unclear. All specified article are pivotal importance research. Overlooking significance any these details can complicate development mitigation strategies.
