Absorbent structures are disclosed comprising a fibrous, superabsorbent core and an integrally attached facing layer. The structures can be made by forming nonwoven webs of mixtures of thermoplastic fibers and superabsorbent fibers, and a web consisting essentially of thermoplastic hydrophobic fibers. The layers are bonded together using thermal bonding. The structures are suitable for use in disposable absorbent products, in particular, pantiliners.
