News about pollution from the apparel and textiles industry at the macro scale has often gone viral. Images of brightly coloured waterways from dyeing processes or mountains of discarded clothing in Chile’s Atacama desert have become powerful symbols of the sector’s footprint.
Far less visible is what happens at the micro scale. Fibre fragmentation occurs continuously across the value chain: from material production and garment manufacturing to consumer use and post-use, and eventual degradation in the natural environment. Yet the scale and implications of fibre shedding remain poorly understood, creating a persistent blind spot for many organisations.
Inclusive approach
Fibre fragments, often referred to as microfibres, are pieces of processed (1) fibrous material that break away from textile structures throughout their lifecycle and during subsequent degradation in the natural environment. Research increasingly shows that all fibre types shed, including man-made cellulosic, synthetic and natural fibres.
This inclusive framing is important to support a shared, industry-wide understanding of the issue. Fibre fragments have now been detected across marine and freshwater systems, terrestrial environments, air, wildlife, and even within human bodies. As evidence grows, they are increasingly recognised as pollutants with potential consequences for environmental and human health.
One of the greatest challenges in addressing fibre fragmentation has been fragmented understanding itself. Inconsistent definitions, limited data, and gaps in research have slowed collective progress.
What can be done now?
Action on fibre fragmentation does not follow a single pathway, nor does it mean detracting from other impact priorities. Instead, it requires progress across multiple stages of the textile lifecycle, where opportunities to reduce fibre loss and release already exist. While further research remains essential, brands and suppliers can work with unifying bodies like the Microfibre Consortium to take practical steps now.
Strategy
As understanding develops, fibre fragmentation can be more effectively integrated into organisational sustainability strategies. Whether approached through a nature, circularity or climate lens, embedding fibre fragmentation into strategy helps ensure it is addressed holistically rather than in isolation.
This may include setting internal priorities based on material risk profiles, aligning fibre fragmentation efforts with broader water or chemicals strategies, or adopting a portfolio approach that recognises the need for multiple interventions across the value chain. While consumer-facing measures, such as washing machine filters, can help capture fibres once shedding has occurred, they should complement, not replace, upstream action at the design and manufacturing stages.
Action: Holistically integrate fibre fragmentation into your existing sustainability strategy and aim to develop a lifecycle approach to address it end-to-end.
Testing
Testing fabrics using established methods helps build an evidence base for action. It enables organisations to understand which variables influence fibre fragmentation across their material portfolios and supports more informed decision-making. Incorporating fibre fragmentation testing into quality manuals for new material developments helps embed this understanding into standard processes.
Existing methods are designed to assess fibre loss under simulated laundering conditions using fabric swatches, enabling root cause understanding. Further work remains ongoing to quantify shedding across the full product lifecycle and through all pathways, including water, soil and air, as well as to address current testing limitations.
Action: Identify a product category, select an established test method, contact an accredited lab, test your fabrics with established test methods and understand which variables affect fibre fragmentation in your material portfolio.
Textile design
Insights from testing should feed directly into fabric design and development decisions, including yarn type, spinning method, staple length, and processing steps such as pretreatment, dyeing and finishing. Design choices made early in the product lifecycle can significantly reduce fibre loss before products reach consumers.
Action: Embed testing insights around fabrics shedding propensities into your design and development processes to drive product improvements.
Manufacturing
Manufacturing processes play a critical role in fibre formation and loss. Throughout textile production, materials are subjected to mechanical and chemical stresses during spinning, weaving or knitting, and subsequent processing stages. These stresses can increase fibre loss from the textile structure, making manufacturing a significant source of fibre fragments.
It has been shown that the dyeing stage can account for up to 95% of the total fibre emissions, and textile industry wastewater can contain fibre fragment concentrations up to a thousand times higher than those found in municipal wastewater. (2)
Action: Spot process-optimisation opportunities and assess technologies to reduce fibre formation and loss. Verify that supplier TSS levels (total suspended solids) meet or exceed the ZDHC Wastewater Foundational requirements.
Refer to TMC and ZDHC’s snapshot guidance documents for brands and suppliers, for actions that can be taken immediately.
Training
Raising awareness within organisations and across supply chains supports more consistent and effective action. Building shared understanding of why fibre fragmentation matters, and equipping teams with the knowledge to identify where they can act, helps turn intent into implementation. Training programmes, practical guidance, and cross-functional workshops can all play a role in embedding fibre fragmentation into everyday decision-making.

Collaboration
Addressing fibre fragmentation requires collective effort. No single organisation can tackle the issue alone. Sharing knowledge with peers, contributing to collaborative research, uploading test results to platforms such as the Microfibre Data Portal, and participating in topic-focused communities all help accelerate progress and scale impact across the industry.
Action: Upload test results to the Microfibre Data Portal to support industry learnings. Consider joining a topic community of organisations working collaboratively to reduce fibre fragmentation.
What’s next?
There is no single solution to fibre fragmentation, and no organisation needs to have all the answers today. What matters is starting somewhere. By embedding fibre fragmentation into strategy, testing, design, manufacturing, training and collaboration, the industry can take practical, science-led steps that deliver impact over time.
The journey to reduce fibre fragmentation will be ongoing, but it must begin with decisive action. When it comes to fibre fragments, small does not mean insignificant.
(1) Processed is intended to encompass fibres that have undergone any form of mechanical or chemical processing. This includes natural fibres that are no longer intheir raw, unprocessed state as found in the environment, as well as fibres derived from synthetic and natural polymers.

About TMC: The Microfibre Consortium (TMC) is a science-led non-profit that leads the Microfibre 2030 Commitment and Roadmap, to mitigate fibre fragment loss and release from all textiles to the natural environment, through global multi-stakeholder collaboration. It is the first and only organisation solely dedicated to this issue and works on behalf of its signatory base, which comprises of brands, retailers, suppliers, researchers, laboratories and affiliated organisations. Since 2018, TMC has worked to connect and translate deep academic research with the reality of commercial supply chain production. Driven by science, with industry change at its core, TMC addresses fibre fragmentation through interventions in design, development and manufacturing, taking a holistic approach in creating change for the lifecycle of textiles.
