摘要： An absorbent composite that includes a fibrous matrix having absorbent material dispersed in bands along the composite's length is disclosed. The bands define liquid distribution zones. On liquid contact, absorbent material swelling occurs and produces a wetted composite having flutes that include swollen absorbent material separated by distribution zones, regions of the composite that are substantially free of absorbent material. Absorbent articles that include the composite are also disclosed.

摘要： Methods for forming an absorbent fibrous composite containing absorbent material dispersed in bands through the composite and along the composite's length are disclosed. The methods generally include depositing a fibrous slurry on a foraminous support to form a web and depositing or injecting absorbent material into the web across its width to provide a web having absorbent material in bands along the composite's length. Drying the web provides a fluted absorbent composite. In one embodiment, the method is a wetlaid method and in another embodiment, the method is a foam-forming method. Preferably, the methods are twin-wire forming methods.
