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 a backing material B-side. The pre-coat B-side and the backing material B-side may include a petroleum based polyol; a vegetable oil, cross-linker, and a catalyst; or a transesterified polyol.
Claims43
A method of making a carpet material comprising:
- providing tufts, a primary backing material, and a pre-coat wherein the pre-coat material comprises the reaction product of a pre-coat A-side comprising a pre-coat isocyanate and a pre-coat B-side comprising a pre-coat vegetable oil, a pre-coat cross-linker, and a pre-coat catalyst;
- engaging the tufts and the primary backing thereby forming griege goods having a top and bottom surface;
- applying the pre-coat onto the bottom surface of the griege goods;
- and
- curing the pre-coat.
