Multiscale mechanical performance of plant-based and hybrid yarns for biodegradable fishing Net
AI summary Read the abstract
Researchers tested yarns made from plant fibers and blends with polyester to see how twisting and material choice affect strength, aiming to find alternatives to fishing nets that persist in the ocean when lost or discarded. The study measured mechanical performance of these yarns at different scales.
Marine plastic pollution from abandoned fishing gear has intensified the search for lower-persistence netting materials that retain adequate mechanical performance. This study investigated how yarn composition and twisting influence plant-based and polyester-containing two-ply yarns across thr...

Influence of knot strength on the mechanical performance of a biodegradable gillnet
AI summary Read the abstract
Researchers compared conventional nylon (PA6) gillnets to biodegradable alternative nets and found the biodegradable material lost even more strength at knots than expected from its weaker base fiber, making it less suitable as a direct replacement. Developing effective biodegradable fishing gear is important because lost or abandoned plastic nets — called ghost gear — are a major source of marine microplastic pollution.
Alternative Rope Materials in Towed Fishing Gear to Reduce Plastic Waste, A Comparative Study of Mechanical Properties and Tolerance Against Wear and Tear
AI summary Read the abstract
Researchers compared the wear tolerance of 14 different rope materials in demersal fisheries, including conventional synthetic polymers and biodegradable alternatives, to identify lower-plastic options that can reduce fishing gear-derived plastic waste.
The effects of mechanical degradation on the quasi static and dynamic stiffness of polyester yarns
AI summary Read the abstract
Researchers examined how different levels of mechanical degradation affect the quasi-static and dynamic stiffness of polyester yarns used in offshore mooring ropes, providing data to better predict performance and failure of these critical marine structures.
Hydrodynamic twisting enables bioinspired cellulose metafibers with exceptional strength and toughness.
AI summary Read the abstract
Researchers created strong, tough plant-based fibers using a twisting technique, achieving strength and toughness matching synthetic fibers and spider silk. Bundling these fibers kept them strong while remaining biodegradable, and they were tested as durable trimmer lines designed to avoid leaving behind plastic residue in farm fields.
Searching for SMART(er) solutions: A laboratory-assessment of microplastic release from aquaculture nets and ropes
AI summary Read the abstract
Researchers tested aquaculture and fishing gear under simulated in-water abrasion to measure microplastic release rates under realistic operational conditions. The study found that net and rope materials shed substantial quantities of microplastics through routine mechanical wear.
