Abstract
A process for producing a synthetic fiber composition with reclaimed post consumer carpet yam, wherein face yam is shaved from post consumer carpet using a shaving device to provide shaved face yam, the shaved face yam is reduced in size, contaminants are removed using mechanical screeners, the shave face yam is melt filtered, and then fiber spun.
