This invention relates to a fibrous laminated material wherein a first fibrous layer comprising a plurality of staple fibers or continuous filaments of a thermoplastic material and a second fibrous layer comprising a plurality of staple fibers or continuous filaments of two or more thermoplastic or other materials are bonded together in a spaced apart bonding pattern having apertures formed therein to form a fibrous laminate having improved liquid distribution and management properties as well as enhanced comfort and softness when placed in contact with human skin. Also disclosed are a method and apparatus for making such a fibrous laminate.

An apparatus for forming a laminated fibrous material comprising: means for providing a fibrous layer comprising a plurality of fibers or filaments of one or more thermoplastic polymeric materials; means for providing a second fibrous layer comprising a plurality of fibers or filaments of two or more thermoplastic polymeric materials; means for bonding said first and second layers at an interface between said layers in a spaced apart bonding pattern comprising compacted bonding regions having a first degree of bonding separated by second, lesser bonded fiber spans; said bonding means comprising a first thermal bonding roll and a second thermal bonding roll opposedly positioned relative to each other, each of said bonding rolls having an outer surface in contact with one of said first and second layers of said first and second layers passing therebetween, said first and second bonding rolls having different raised bonding patterns on said outer surfaces thereof, said first bonding roll having a spaced apart raised bonding pattern on the outer surface thereof and said second bonding roll having a plurality of raised bonding points on the outer surface thereof; means for operating said first bonding roll at a first rotational speed and means for operating said second bonding roll at a second rotational speed, said operating means ensuring that said first and second rotational speeds differ within a range of from about 4 percent to about 50 percent; means for maintaining said first bonding roll at a first bonding temperature within the range of from about 260°F. to about 285°F. and means for maintaining said second bonding roll at a second bonding temperature within the range of from about 270°F. to about 320°F., said maintaining means maintaining said first and second bonding rolls at different bonding temperatures; and said bonding rolls forming apertures within said bonding regions, said apertures being substantially free of fibers through the thickness of said laminated fibrous material.
