  • Publication number: 20050260351
    Abstract: The present invention includes a method for making a bio-based carpet material by providing tufts, a backing, a pre-coat, and a backing material wherein the pre-coat includes the reaction product of a pre-coat A-side having a pre-coat isocyanate and a pre-coat B-side and the backing material includes the reaction product of a backing material A-side having an isocyanate and a backing material B-side. The pre-coat B-side and the backing material B-side may include a polyol derived from petroleum; a vegetable oil, cross-linker, and a catalyst; or a transesterified polyol.
