摘要:
An article having as a component a section of nonwoven web formed predominately of polymeric fibers is disclosed. The section of nonwoven web may have a pattern of consolidating bonds impressed on the surface. The bonds may have at least one bond shape; and the bond shape may have a greatest measurable length and greatest measurable width. The shape may have a convex portion and an aspect ratio of length/width of at least 2.0. Other features may be imparted relating to the density, orientations and overlap of rows relative the machine direction of the web. The bond shape reflects the shape of a corresponding bonding protrusion on a bonding roller. It is believed that the shape, density, orientation, and overlap of the rows of the bonding protrusions affect air flow through the bonding nip in a way that may be utilized to enhance loft of the resulting bonded nonwoven web.
