Abstract

A panel that is used in forming the panel portions of recreational sport balls, and methods for the production thereof, are provided. The panels may be affixed to an inflatable bladder and include a base layer of polymeric material and a covering layer bonded thereto. The base layer may be bonded to a substrate layer of nonwoven cloth. The covering layer includes at least one conditioning agent that is either a water repellant agent to reduce water and sweat absorption, or an antistatic agent to repel dirt and dust, but may include both agents. The conditioning agent(s) may penetrate into the outer surface of the base layer to form the covering layer bonded thereto. Alternatively, the base layer may resist penetration by the conditioning agent(s) such that the covering layer is bonded to the surface of the base layer. The covering layer may further include an anti-bacterial agent.

Claims

1. In an inflatable ball of a selected size and a selected configuration and having an outer surface thereof, the improvement comprising a covering layer bonded to a portion of said outer surface, wherein said covering layer includes an anti-static conditioning agent.

2. A ball according to claim 1 wherein said covering layer includes a water repellant agent.

3. A ball according to claim 2 wherein said water repellant agent and said anti-static agent are cross-linked.

4. A ball according to claim 2 wherein said water-repellant agent is selected from a group consisting of fluorine based and silicon based water repellants.

5. A ball according to claim 1 wherein said anti-static agent is a modified fatty salt.

6. A ball according to claim 1 wherein said covering layer further includes an anti-bacterial agent.

7. A ball according to claim 6 wherein said anti-bacterial agent is 2-n-octyl-4-isothiazolin-3-one.

8. A ball according to claim 1 wherein said outer surface is defined by a base layer and wherein said covering layer is defined by a diffusion layer of said conditioning agent diffused into an outer surface region of said base layer.

9. A ball of a selected size and configuration, said ball comprising an inflatable bladder and a plurality of panel portions affixed thereto, wherein each of said panel portions includes a base layer formed of a polymeric material and a covering layer bonded to said base layer, said covering layer including both a water repellant agent and an anti-static agent that do not penetrate into the entire depth of said base layer.

10. A ball according to claim 9 wherein said inflatable bladder includes a plurality of ribs projecting radially outwardly from an outer surface thereof thereby to define a configuration of regions of said outer surface wherein each region is bounded by selected ones of said ribs, and wherein said panel portions are affixed to said bladder within said configuration of regions such that peripheral margins of said panel portions confront said ribs.

11. A ball according to claim 9 wherein said base layer includes a polyurethane material.

12. A ball according to claim 9 wherein said base layer is bonded to a substrate layer.

13. A ball according to claim 12 wherein said substrate layer is formed of a nonwoven cloth.

14. A ball according to claim 9 wherein said covering layer further includes an anti-bacterial agent.

15. In a ball of a selected size and a selected configuration and having an outer surface thereof, the improvement comprising a covering layer bonded to a portion of said outer surface, wherein said covering layer includes both a water repellant conditioning agent and an anti-static conditioning agent.

16. A ball according to claim 15 wherein said water repellant agent and said anti-static agent are cross-linked.

17. A ball according to claim 15 wherein said water-repellant agent is selected from a group consisting of fluorine based and silicon based water repellants.

18. A ball according to claim 15 wherein said anti-static agent is a modified fatty salt.

19. A ball according to claim 15 wherein said covering layer further includes an anti-bacterial agent.

20. A ball according to claim 19 wherein said anti-bacterial agent is 2-n-octyl-4-isothiazolin-3-one.

21. A ball of a selected size and configuration, said ball comprising an inflatable bladder and a plurality of panel portions affixed thereto, wherein each of said panel portions includes a base layer formed of a polymeric material and a covering layer bonded to said base layer, said covering layer including both a water repellant conditioning agent and an anti-static conditioning agent.

22. A ball according to claim 21 wherein said covering layer further includes an anti-bacterial agent.
