Abstract

This invention relates to a synthetic turf comprised of a backing, a synthetic grass-like surface which is comprised of textured and non-textured grass-like fibers that are secured to the backing. The synthetic turf further comprises a fill layer comprised of substantially ambient rubber spread substantially uniform throughout the textured and non-textured grass-like fibers. This invention also relates to synthetic turf systems.

Claims (49)

1. A synthetic turf comprising:

(a) a primary backing having about 15 weaves/inch (Pic), a weight of about 8 oz/square yard, and apertures of about 2 to 3 inches in diameter;

(b) a secondary backing having about 13 weaves/inch (Pic), a weight of about 20 oz/square yard, and apertures of about 2 to 3 inches in diameter, and wherein said primary and secondary backing are cut into about 12 to 15 feet widths;

(c) a synthetic grass like surface comprised of textured and non-textured grass-like fibers, wherein the textured grass like fibers are comprised of melamin/phenol/formaldehyde molding compounds (MPF) having a denier of between 6 and 7500 denier and wherein the non-textured grass-like fibers are comprised of Teflon coated (TtC) polyethylene having a denier of about 10,000 and wherein said textured and non-textured grass-like fibers have a pile weight of about 55 oz/Square yard and a pile height of between 2 to 3 inches; and

(d) a fill layer comprised of substantially ambient rubber and spread substantially uniform throughout said textured and non-textured grass-like fibers, wherein said ambient rubber comprises:

(i) acetone extract in a range of about 8 wt % to about 22 wt %;

(ii) ash in a range of about 0 wt % to about 8 wt %;

(iii) carbon black in a range of about 26 wt % to about 38 wt %

(iv) natural rubber in a range of about 10 wt % to about 35 wt %;

(v) rubber hydrocarbon in range of about 42 wt % to about 56 wt %; and

wherein the remainder comprises moisture.

2. The synthetic turf of claim 1 , wherein the primary backing is treated with a polyurethane pre-coat.

3. The synthetic turf of claim 1 , wherein the secondary backing further comprises impermeable inert urethane a polyurethane adhesive coating on an underside thereof, for facilitating adhesion of the synthetic turf to a supporting surface.

4. The synthetic turf of claim 1 , wherein the textured grass-like fiber and the non-textured grass-like fiber are yarn.

5. The synthetic turf of claim 1 , wherein said textured grass-like fibers have a pile height at least 25% less than the pile height of the non-textured pile.

6. The synthetic turf of claim 1 , wherein said textured grass-like fibers are tufted into said primary and secondary backings and have a tuft bind to said primary and secondary backing of 21 lbs/Square inch.

7. The synthetic turf of claim 1 , having a tufting gauge of between 0.25 and 0.75.

8. A synthetic turf comprising:

(a) a primary backing having apertures;

(b) a secondary backing having apertures and wherein said primary and secondary backing are cut into widths;

(c) a synthetic grass like surface comprised of textured and non-textured grass-like fibers; and

(d) a fill layer comprised of substantially rubber and spread substantially uniform throughout said textured and non-textured grass-like fibers, wherein said ambient rubber comprises:

(i) acetone extract in a range of about 8 wt % to about 22 wt %;

(ii) ash in a range of about 0 wt % to about 8 wt %;

(iii) carbon black in a range of about 26 wt % to about 38 wt %

(iv) natural rubber in a range of about 10 wt % to about 35 wt %;

(v) rubber hydrocarbon in range of about 42 wt % to about 56 wt %; and

wherein the remainder comprises moisture.

9. The synthetic turf of claim 8 , wherein said primary backing has a weight of about 3 to about 15 oz/Square yard.

10. The synthetic turf of claim 8 , wherein said secondary backing weight has a weight of about 5 to about 30 oz/Square yard.

11. The synthetic turf of claim 8 , wherein the yam is comprised of melamin/phenol/formaldehyde molding compounds (MPF).

12. The synthetic turf of claim 8 , wherein the non-textured grass-like fiber is a yarn coated with Teflon (TtC) polyethylene.

13. The synthetic turf of claim 8 , wherein said synthetic grass-like surface has a pile weight of at least 50 oz/Square yard.

14. The synthetic turf of claim 8 , wherein said synthetic grass-like surface has a has a pile height exceeding about from 0.5 to about 4.0 inches.

15. The synthetic turf of claim 8 , wherein said textured and non-texture rass-like fibers have a denier of between about 5 to 15,000 denier.

16. The synthetic turf of claim 8 , wherein said primary and said secondary backing have apertures of about 1 to 3 inches in diameter.

17. The synthetic turf of claim 8 , wherein the primary backing is treated with a polyurethane pre-coat.

18. The synthetic turf of claim 8 , wherein the secondary backing comprises impermeable inert urethane and a polyurethane adhesive coating on an underside thereof, for facilitating adhesion of the synthetic turf to a supporting surface.

19. The synthetic turf of claim 8 , wherein the textured grass-like fiber and the non-textured grass-like fiber are yarn.

20. The synthetic turf of claim 8 , wherein said textured grass-like fibers have a pile height at least 25% less than the pile height of the non-textured pile.

21. The synthetic turf of claim 8 , wherein said textured grass-like fibers are tufted into said primary and secondary backings with a tuft bind to said primary and secondary backing of 21 lbs/Square inch.

22. The synthetic turf of claim 8 , having a tufting gauge of between 0.25 and 0.75.

23. A fill layer for a synthetic turf having a primary backing with apertures and wherein said primary backing is cut into widths and synthetic grass-like surface fibers, the fill layer comprising substantially ampient rubber spreadable in a substantially uniform manner throughout said grass-like fibers, wherein said ambient rubber comprises:

(i) acetone extract in a range of about 8 wt % to about 22 wt %;

(ii) ash in a range of about 0 wt % to about 8 wt %;

(iii) carbon black in a range of about 26 wt % to about 38 wt %

(iv) natural rubber in a range of about 10 wt % to about 35 wt %;

(v) rubber hydrocarbon in range of about 42 wt % to about 56 wt %; and

wherein the remainder comprises moisture.
