- 8. The carpet tile of claim 7 wherein the backing sheet comprises a glass fiber sheet material, the adhesive layer comprises an ethylene vinyl acetate latex, and the backing layer comprises a polyvinyl chloride resin to form a carpet tile material.
- 9. The carpet tile of claim 7 wherein the backing sheet comprises a glass fiber sheet material, the adhesive layer comprises a hot-melt adhesive, and the backing layer comprises a bitumen backing layer.
- 10. The carpet of claim 1 wherein the yarn material is selected from yarn of different colors to provide for a multicolored wear face surface of the fusion-bonded carpet.
- 11. The carpet of claim 1 wherein each rope form comprises generally straight and parallel yarn material formed into untwisted rope forms.
- 12. The carpet of claim 1 wherein the rope forms have a general diameter of from about 3 mm to 13 mm.
- 13. The carpet of claim 1 wherein the yarn material of the rope form is yarn material having selected characteristics selected from the group consisting of yarn size, yarn ply, yarn twist level, yarn twist direction, yarn color, yarn heat setting properties and combinations thereof.
- 14. The carpet of claim 1 wherein each rope form comprises from about 2 to 20 strands of yarn material.
- 15. The carpet of claim 1 wherein each rope form bundle comprises from about 4 to 12 rope forms.
- 16. The carpet of claim 1 wherein the rope form securing means or the rope form bundle securing means comprise an adhesive means to retain the integrity of the rope form or rope form bundles.
- 17. The carpet of claim 1 wherein one of the rope forms in a rope form bundle is of one color and other rope forms are of a different color.
- 18. The carpet of claim 1 wherein the adhesive coating layer is selected from the group of adhesives consisting of a hot melt adhesive and a polyvinyl chloride adhesive.
- 19. The carpet of claim 1 wherein the multiple strands of yarn material are twisted to form twisted rope forms, and include spirally wrapped filament about the twisted rope forms to maintain the integrity of the twisted rope forms.
- 20. The carpet of claim 1 wherein the carpet comprises a carpet tile and includes a backing layer bonded to the backing sheet.
- 21. The carpet of claim 1 which includes single yarn fibers having one end secured to the layer of adhesive material and the other end forming part of the face wear surface.
