Abstract
A method for making a fire retardant coil zipper is disclosed. The method involves using a fire retardant material bath exhaust process, that is, immersing the zipper in an aqueous bath of the fire retardant material and heating the bath under pressure to thereby impregnate the zipper with the fire retardant material while exhausting the bath.
