Abstract:
In a process forming a laminate suited for use in preparing disposable absorbent products byoverlaying a substrate over the particulate polymeric absorbent and thereby forming a laminate trapping the polymeric absorbent between said first nonwoven fibrous web and said substrate; passing the laminate having the polymeric absorbent trapped between the first nonwoven web and second substrate through pressure roll means for imparting indentations in the laminate; and then, adhesively bonding the first nonwoven web and overlaid substrate at a plurality of points thereby forming discrete regions within the laminate and thus fixing a portion of the polymeric absorbent within said regions, the improvement which comprises: adhesively bonding the first nonwoven fibrous web to said overlaid substrate solely by means of the pressure supplied by said roller means and effecting adhesion through the polymeric resin utilized in bonding the fibers in the web and said adhesion effected without the addition of water or heat sufficient to raise the adhesive temperature above about 100Â° C.
