Abstract

A pulpless core is provided with flexibility for superabsorbent expansion by using elastic strands stretched and coupled to a nonwoven layer, and then relaxed partially to create receiving valleys (puckers) and the puckers are provided with superabsorbent polymer, and then a layer of nonwoven or acquisition film can be coupled on top of nonwoven/elastic/sap carrier layers to create an absorbent core laminate. A tubular core can be created and placed into a product with or without additional absorbent material between adjacent tubular members. A printed back sheet corresponding to either the tubular core shape, or void spaces between tubular members can be provide. A forming drum pocket can be profiled to match tube or tube shaped zones and elastic placements between adjacent tubes, if desired.
