Summary
Standardized methods are needed to assess microfiber pollution from textiles. This review identifies fabric and knit construction parameters that can reduce microfiber shedding during laundering, promoting eco-design for sustainable textiles.
Area of Science:
- Environmental Science
- Materials Science
- Textile Engineering
Background:
- Microfiber pollution from laundering is a significant environmental concern.
- Lack of standardized assessment methods leads to inconsistent data on microfiber shedding.
- Engaging producers and consumers in solutions like eco-design requires clear, succinct information.
Approach:
- Systematic review using PRISMA methodology.
- Analysis of 32 selected articles on microfiber shedding from knit fabrics.
- Critical evaluation of fabric parameters (fiber polymer, length, yarn twist) and knit construction (gauge, structure).
Key Points:
- Identifies fabric and knit construction parameters influencing microfiber shedding.
- Highlights agreed-upon parameters for reducing microfiber release from knit textiles.
- Critically evaluates contradictory findings and inconsistencies in current research.
Conclusions:
- Agreed-upon fabric and construction parameters can reduce microfiber pollution from knit textiles.
- Calls for more systematic studies to standardize microfiber shedding assessment.
- Emphasizes the need for cross-industry collaboration and comprehensive guidelines for sustainable textile practices through eco-design.
