Polyester polymer fiber twisting aerosol

Mixed airborne fibers and particulate generated while twisting polyester polymer fiber.

Airborne form

fiberdustaerosol

The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.

Evidence

A NIOSH health-hazard evaluation at a polyester-fiber twisting operation found that aerosols were 30–45% fibrous and 55–70% particulate; employees reported respiratory and skin symptoms, while measured dust concentrations were below the report's evaluation criteria.
