Does water temperature affect how many microplastics clothes release?

Yes, water temperature has a measurable effect on microplastic shedding from synthetic garments. Research shows that washing at higher temperatures (60 degrees Celsius versus 30 degrees Celsius) can increase microfiber release by 30-40%. Hot water weakens the bonds between synthetic polymer chains, causing more fibers to break free from the fabric surface during agitation.

Cold washing reduces shedding but does not eliminate it. Even in cold water with gentle agitation, synthetic garments release thousands of microfibers per cycle. The combination of cold water, gentle cycle, full loads, and liquid detergent minimizes shedding to the lowest achievable level for synthetic laundry. Adding a microfiber-catching laundry bag provides further reduction.

For natural-fiber clothing, water temperature is less of a health concern since any fibers shed are biodegradable. However, cold washing is still recommended for garment longevity. The fundamental point remains: no amount of washing optimization eliminates microplastic pollution from synthetic clothing. Only choosing natural fibers truly solves the problem. ONDU's brands are designed to perform beautifully when washed on cold, gentle cycles.
