exploratory flammability experiments with fabrics contaminated with gasoline

the rate of evaporation of gasoline from 18 fabrics varying widely in fiber composition and construction was measured and found to be inversely related to fabric weight, and directly related to the area wetted by the gasoline. for a given fabric weight, knitted fabrics tended to have a lower rate of evaporation than more compact, woven fa..
