The present invention provides bond patterns for nonwoven fabrics and laminates thereof, and a process of producing the bond patterns. The bond patterns provides highly distinct and recognizable patterns without significantly reducing the physical properties of the nonwoven fabrics. The bond pattern comprises a series of unbonded regions in a geometric pattern of regularly bonded regions, and each unbonded region forms an unbonded area enclosed by the bonded regions surrounding the unbonded region, whereby the series of unbonded regions forms a visually recognizable pattern, wherein the bonded regions cover from about 3% to about 50% of the surface of the nonwoven web, and wherein each of the unbonded areas has a size equal to or less than about 0.3 cm.sup.2.
A pattern bonded nonwoven fabric having at least one distinctly and visually identifiable pattern of unbonded areas, said fabric having a geometrically repeating and visually discernable base pattern of bonded regions, said identifiable pattern comprising a series of unbonded regions in said geometric pattern of bonded regions, each unbonded region forming an unbonded area which is enclosed by said bonded regions surrounding said unbonded region, wherein said series of unbonded areas forms said identifiable pattern, wherein said bonded regions cover from about 3% to about 50% of the surface of said nonwoven fabric, wherein the size of each of said unbonded areas is equal to or less than about 0.3 cm.sup.2, and wherein said nonwoven fabric comprises a nonwoven fiber web.
