发明名称 Reticulated absorbent composite
摘要 An absorbent composite ( 10 ) having a fibrous matrix that includes absorbent material is disclosed. The fibrous matrix defines voids ( 14 ) and passages between the voids, which are distributed throughout the composite. Absorbent material ( 18 ) is located within some of the voids ( 14 ). Absorbent material located in these voids is expandable into the void. In a preferred embodiment, the composite's fibrous matrix includes resilient and matrix fibers ( 16 ). The composite optionally includes a wet strength agent.
