| abstract |
A carpet tile and method of production wherein the carpet tile comprises a carpet tile having a fibrous face (14), such as a tufted face, and a fibrous back surface (16) secured to a primary backing (12) and comprising three separate hot melt coating composition layers (18, 20, 24) and a secondary backing (26) on the back surface of the carpet tile. The carpet tile is produced by coating a thick backing layer (24) of a rubber-modified bitumen coating composition onto a secondary backing sheet material (26) and separately coating a first precoat layer (28) comprising a hot melt petroleum resin or bitumen and a second layer (20) comprising a hot melt bitumen composition containing a flexible vinyl adhesive resin, like ethylene vinyl acetate, onto a fibrous back surface of a carpet material having a primary backing sheet (12) containing a fibrous face wear surface and laminating the surface of the second layer (20) to the surface of the backing layer (24) to provide a carpet tile having dimensional stability, good lay flat characteristics and capable of production by an in-line production method. |
