Summary
Textile microplastic shedding is significantly higher from knitted fabrics compared to woven ones, with satin weaves releasing the most fibers. Friction is a key factor influencing microplastic release during washing.
Area of Science:
- Environmental Science
- Materials Science
- Textile Engineering
Background:
- Microplastics, defined as plastic particles <5mm, pose ecological and health risks.
- Textile microplastics are a significant contributor to environmental pollution.
- Understanding textile microplastic shedding is crucial for mitigation strategies.
Purpose of the Study:
- To investigate the relationship between textile microplastic shedding and fabric structure.
- To identify key factors influencing microplastic release during household washing.
- To reduce microplastics pollution from textiles.
Main Methods:
- Simulated household washing using orthogonal experimental design.
- Varied fabric types, steel ball counts, washing temperature, and time.
- Analyzed microplastic shedding under optimal washing conditions with varying friction and insolation time.
Main Results:
- Knitted fabrics shed significantly more microplastics than woven fabrics.
- Satin fabrics exhibited the highest microplastic release, while plain fabrics released the least.
- The amount of friction applied was a significant factor in microplastic production.
Conclusions:
- Fabric structure, particularly knit vs. weave and weave type (satin vs. plain), strongly influences microplastic shedding.
- Washing conditions and external factors like friction play a critical role in microplastic release.
- Findings provide insights for developing textiles and washing practices to minimize microplastic pollution.
