Abstract:
A composite absorbent structure, comprising:a. a first wicking layer comprising wettable fibers, wherein the first wicking layer exhibits a vertical liquid flux rate value at a height of about 15 centimeters of at least about 0.08 grams of liquid per minute per gram of absorbent structure per meter length of the first wicking layer;b. a second retention layer comprising a hydrogel-forming polymeric material; andc. a bonding agent for bonding said first wicking layer and said second retention layer to form a composite absorbent structure having a minimum contact intimacy ratio for providing a liquid transport function and a liquid retention function such that the first wicking layer and the second retention layer are combined together in a manner to obtain a contact to achieve liquid transport and liquid retention functions at a length of at least about 15 centimeters, a saturated capacity of at least about 5 grams of liquid per gram of composite absorbent structure, and an Absorbent Capacity at 15 cm of at least about 5 grams of liquid per gram of second retention layer.
