Abstract
The present invention provides a golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing therein.

Claims17
A golf ball having an outer surface comprising a plurality of dimples covering greater than 70 percent of the outer surface, wherein at least 20 percent of the dimples incorporate directional surface texturing comprised of 3 or more substantially parallel linear channels having a U-shaped cross-section with a depth of less than 0.005 inch.
The golf ball of claiml, wherein the dimples are circular in plan shape and have a diameter of 0.11 inch to 0.22 inch and the linear channels have a channel radius of 0.01 inch to 0.08 inch and a channel depth of 0.0003 inch to 0.003 inch.
The golf ball of claiml, wherein each of the dimples has a depth and the linear channels have depths that are directly proportional to the depth of the dimple such that a dimple with a greater dimple depth has a greater channel depth.
