The absence of standardized procedures to assess microfiber pollution released during laundering, alongside textile complexities, has caused incomparability and inconsistency between published methodologies, data formats, and presentation of findings. Yet, this information needs to be clear and succinct to engage producers and consumers in reducing microfiber pollution through solutions, such as eco-design. This review analyses source directed interventions through design and manufacturing parameters that can prevent or reduce microfiber shedding from knit fabrics during washing. Contradicting results are critically evaluated and future research agendas, alongside potential areas for voluntary and involuntary sustainable incentives are summarized. To do this, a systematic review was carried out, using the PRISMA approach to verify which fabrics had been investigated in terms of microfiber shedding. Using selected keywords, a total number of 32 articles were included in this review after applying carefully developed inclusion and exclusion criteria. The influence of fabric parameters such as fiber polymer, length of fibers and yarn twist alongside fabric construction parameters such as gauge of knit and knit structure are critically evaluated within the systematically selected studies. This review highlights the agreed upon fabric parameters and constructions that can be implemented to reduce microfiber pollution released from knit textiles. The complexities and inconsistencies within the findings are streamlined to highlight the necessary future research agendas. This information is critical to facilitate the adoption of cross-industry collaboration to achieve pollution reduction strategies and policies. We call for more systematic studies to assess the relationship between individual textile parameters and their influence on microfiber shedding. Additionally, studies should work toward standardization to increase comparability between studies and created more comprehensive guidelines for policy development and voluntary actions for the textile and apparel industry to participate in addressing more sustainable practises through eco-design.
由于缺乏评估洗衣过程中释放的微纤维污染的标准化程序，再加上纺织品的复杂性，导致已发表的方法、数据格式和研究结果呈现之间存在不可比性和不一致性。然而，为了通过生态设计等解决方案促使生产商和消费者减少微纤维污染，这些信息需要清晰简洁。本综述分析了通过设计和制造参数进行的源头干预，这些参数可以防止或减少针织面料在洗涤过程中产生微纤维脱落。批判性地评估了相互矛盾的结果，并总结了未来的研究议程以及潜在的自愿和非自愿可持续激励领域。为此，采用 PRISMA 方法进行了系统综述，以验证在微纤维脱落方面已经研究了哪些面料。使用选定的关键词，在仔细制定纳入和排除标准后，共有 32 篇文章被纳入本综述。系统选择的研究中批判性地评估了纤维聚合物、纤维长度和纱线捻度等面料参数以及针织物的规格和针织结构等面料结构参数对面料的影响。本综述强调了可以实施的减少针织纺织品释放的微纤维污染的商定面料参数和结构。对研究结果中的复杂性和不一致性进行了简化，以突出必要的未来研究议程。这些信息对于促进跨行业合作以实现减少污染的策略和政策至关重要。我们呼吁进行更多的系统研究，以评估各个纺织参数与其对面料微纤维脱落的影响之间的关系。此外，研究应朝着标准化方向努力，以提高研究之间的可比性，并为纺织服装行业制定更全面的政策制定和自愿行动指南，以通过生态设计参与更可持续的实践。
