Scientists at Heriot-Watt University spent four years developing a revolutionary 5-point grading system that measures exactly how many harmful fibers your clothes shed during each wash.

Your everyday clothing releases microscopic fibers thinner than a hair strand but potent enough to cause cellular damage and inflammation in marine life and humans alike.

Dr. Lisa Macintyre's research team discovered their simple visual grading method outperforms expensive ISO standards at detecting minimal fiber shedding - making industry-wide testing finally feasible.

Forty-six dedicated participants, from fashion professionals to everyday consumers, meticulously evaluated 100 fabric samples over two years to perfect this groundbreaking scale.

The fashion industry currently lacks any regulated standards for acceptable fiber shedding rates, leaving manufacturers free to use materials that pollute our oceans without consequences.
