A research project examined the feasibility of recycling polypropylene carpeting waste into a meltable, thermoformable backcoating. The backcoating would be used in polyester carpeting utilized as molded automobile trunk linings. The investigation considered the recycling of two different polypropylene floor coverings: carpeting that contained a polyethylene binder fiber instead of a polyvinyl acetate binding component, and carpeting that contained a noncrosslinked polyvinyl acetate copolymer latex as the binding component. The trials evaluated dry, hot melt, and extrusion film coating application methods. Dry waste application methods reduced the waste to a flowable flock type of material, but this material was not suitable as a backcoating for polyester carpeting. Hot melt application methods produced a molten waste with a high viscosity that was also unsuitable backcoating material that could be applied simply and inexpensively. 8 refs.
