Polyester and Airborne Microplastics Study
Thursday 29th October, 2026
The Cotton Foundation funded a small study comparing airborne microplastic particles near people wearing polyester and cotton shirts. The hook was a surprising, wearable angle on pollution: polyester days showed about 42% more particles nearby, giving the cotton industry a newsworthy finding while leaving important questions about exposure and health unanswered.
Why it worked: It turned a broad pollution issue into a personal, measurable stat—“42% more particles in your breathing zone”—from a wearable A/B test.
The lesson: Consider running a simple A/B field test that quantifies a surprising, personal-impact stat, then pitch the single headline number hard.
