    摘要: 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.
