Abstract

Absorbent composites are provided that include a nonwoven top layer having hydrophilic fibers and an absorbent core layer directly or indirectly attached to the nonwoven top layer, wherein the absorbent core layer comprises a through-air-bonded nonwoven. The absorbent composites may include a combination of (i) a composite-run-off value of less than 50% as determined by ISO 9073-11, (ii) a composite-absorption capacity of at least 600% as determined by ISO 9073, and (iii) a composite-rate of absorption of less than 10 seconds for a 5 ml liquid sample as determined by D824-94. The absorbent composites may include an optional film layer attached to the absorbent core layer.
