A nonwoven web having an advantageous bond pattern impressed by a bonding pattern on a roller is disclosed. The bonding pattern is selected to have a bonding area percentage from 6 to 14 percent, which provides a desirable level of bonding of filaments and/or fibers for mechanical strength, while retaining desirable pliability and/or liquid handling characteristics. The bonding area is also relatively highly dispersed, which provides for a relatively greater number of bonded areas for the selected bonding area percentage. The greater number of bonded areas is believed to provide improved structural integrity while still retaining pliability and/or liquid handling characteristics, and also provide for enhanced visual detail and complexity. The relatively highly dispersed bonding area is believed to be particularly effective for nonwoven web materials having three or more layers, with outer layers of polymeric filaments, and even more particularly, one or two outer layers of fine filaments.
A nonwoven web formed at least in part of filaments, libers or a combination thereof, comprising a pattern of bonded areas at which differing ones of the fibers and/or filaments are bonded together, the pattern of bonded areas having been impressed into the nonwoven web by one or more bonding rollers each having a cylindrical surface bearing a pattern of bonding surfaces, the bonding surfaces of the one or more rollers in combination forming a bonding area having a bonding area percentage from 6 to 14 percent, wherein the bonding area has an average bonding area dispersion distance of no greater than 5 mm;
A nonwoven web comprising a first layer of polymeric filaments, a second layer of polymeric filaments, and third layer disposed at least partially between the first and second layers, and further comprising a pattern of bonded, areas at which polymeric filaments of the first layer are bonded with polymeric filaments of the second layer, the pattern of bonded areas having been impressed into the nonwoven web by one or more bonding rollers each having a cylindrical surface bearing a pattern of bonding surfaces, the bonding surfaces in combination forming a bonding area having a bonding area percentage from 6 to 14 percent, wherein the bonding area has an average bonding area dispersion distance of no greater than 5 mm.
