Polyamid and polyester mixed waste carpeting is recycled for use in fabricating new carpeting and pile fabrics by adding a copolymer derived from an alkene monomer and an unsaturated epoxy-containing monomer as a compatibilizing agent. The mixture, e.g. of 75-90% polyamide, 10-25% of polyester and 5-20% of the copolymer, which may be a copolymer of ethylene and glycidyl methacrylate, is subjected to a melt extrusion fibre spinning process to form yarn.
