Abstract

Described herein are methods for manufacturing resilient floor coverings made from non-vinyl materials.

First claim

What is claimed is:

1. A method for making a resilient floor covering comprising:
providing a backing portion having a top surface and an opposing bottom surface configured to substantially abut the floor when the resilient floor covering is placed in the selected orientation, wherein the backing portion comprises at least one backing layer, wherein the at least one backing layer of the backing portion comprises a first primary backing layer, a second primary backing layer, and a secondary backing layer;
applying a decorative portion having a top surface and an opposing bottom surface, wherein the decorative portion is configured to overlie the backing portion such that the to surface of the backing portion contacts the bottom surface of the decorative portion, and wherein the decorative portion comprises an ink layer; and
applying a wear layer having an exposed outer surface configured for exposure to the ambient environment and an opposed bottom surface configured to substantially overlie the decorative portion of the floor covering, and
wherein the resilient floor covering does not comprise vinyl polymer material.

2. The method of claim 1 , further comprising applying one or more tie layers thereto the top surface of the backing portion, wherein the decorative portion is applied thereto the tie layer applied to the backing portion.

3. The method of claim 2 , wherein the bottom surface of the decorative portion is substantially directly applied to the top surface of the backing portion or the one or more tie layers are applied thereto the backing portion.

4. The method of claim 1 , further comprising applying one or more tie layers thereto the top surface of the decorative portion, wherein the wear layer is applied thereto the tie layer applied to the decorative portion.

5. The method of claim 4 , wherein the wear layer is substantially directly applied to the top surface of the decorative portion or the tie layer applied thereto the decorative portion.

6. The method of claim 1 , wherein the first and second primary backing layers comprises composites of post-industrial carpet or composites of post-consumer carpet.

7. The method of claim 1 , wherein the wear layer has an exposed outer surface configured for exposure to the ambient environment.

8. The method of claim 1 , wherein the first and second primary backing layers comprises at least one of: low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), EMA, EVA, PE-PP rubber, conventional thermoplastic elastomers (TPEs), conventional thermoplastic olefins (TPOs), alpha-olefin polyethylene co-polymers, PET, or ethylene butyl acrylate (EBA).

9. The method of claim 1 , wherein the secondary backing layer defines the bottom surface of the backing portion and the first and second primary backing layers can be configured to substantially overlie the secondary backing layer.

10. The method of claim 9 , wherein the secondary backing layers comprises at least one of: OPP, woven PE, nonwoven PE, woven PP, nonwoven PP, woven PET, nonwoven PET, woven nylon, or nonwoven nylon.

11. The method of claim 1 , further comprising interposing a fiberglass layer there between the first and second primary backing layers.

12. The method of claim 1 , wherein one primary backing layer of the first and second primary backing layers defines the top surface of the backing portion of the floor covering.

13. The method of claim 1 , wherein at least one of the backing layers comprises substantially linear ethylene polymers and homogeneously branched linear ethylene polymers.

14. The method of claim 13 , wherein at one of the backing layers further comprises: another homogeneously branched ethylene polymer, low density polyethylene, heterogeneously branched LLDPE, heterogeneously branched ULDPE, medium density polyethylene, high density polyethylene, grafted polyethylene, ethylene acrylic acid copolymer, ethylene vinyl acetate copolymer, ethylene ethyl acrylate copolymer, polystyrene, polypropylene, polyester, polyurethane, polybutylene, polyamide, polycarbonate, rubbers, ethylene propylene polymers, ethylene styrene polymers, styrene block copolymers, or vulcanates.

15. The method of claim 1 , wherein the ink layer defines the top surface of the decorative portion.

16. The method of claim 1 , wherein the ink layer defines the bottom surface of the decorative portion.

17. The method of claim 1 , wherein the ink layer comprises inks selected from a group consisting of: water based, soy-based, or solvent-based pigments.

18. The method of claim 1 , wherein the wear layer is positioned adjacent to the decorative portion such that the top surface of the decorative portion contacts the bottom surface of the wear layer.

19. The method of claim 18 , wherein the wear layer comprises at least one of: polyethylene terephthalate (PET), polyurethane, polypropylene, polytrimethylene terephthalate (PTT), Nylon 6, or Nylon 6, 6.

20. The method of claim 2 , wherein the tie layer comprises at least one of: water borne extrusion coating primers, polyethyleneimine (PEI), conventional acrylic materials, maleic anhydride (MAH), ethylene-methyl acrylate (EMA), or ethylene-vinyl acetate (EVA).

21. The method of claim 4 , wherein the tie layer comprises at least one of: water borne extrusion coating primers, polyethyleneimine (PEI), conventional acrylic materials, maleic anhydride (MAH), ethylene-methyl acrylate (EMA), or ethylene-vinyl acetate (EVA).

22. The method of claim 1 , wherein the decorative portion comprises a decorative layer, wherein the decorative layer defines the bottom surface of the decorative portion of the floor covering, and wherein the ink layer is configured to substantially overlie the decorative layer.

23. The method of claim 22 , wherein the decorative layer comprises at least one of: oriented polypropylene (OPP), woven polyethylene (PE), nonwoven PE, woven polypropylene (PP), nonwoven PP, woven PET, nonwoven PET, woven nylon, nonwoven nylon, conventional papers, conventional foils.
