Abstract
A method of oil removal wherein glass fibers are formed from melted glass, sprayed with a binder, and collected on a conveyor in a continuous process. A woven scrim of continuous glass filaments is fed from a roll to the conveyor along with the glass fibers. The scrim and fibers pass under a sizing roll which compresses the fibers into a mat, and then through a curing oven to cure the binder. The scrim-reinforced glass fiber mat is cut into lengths, such as one hundred feet or two hundred feet, and rolled into rolls for eventual use as an oil absorbent primarily to clean up oil spills from oil tankers.
