An absorbent composite (10) that includes a fibrous matrix having absorbent material dispersed in bands (12) along the composite's length is disclosed. The bands define liquid distribution zones (14). On liquid contact, absorbent material material swelling occurs and produces a wetted composite having flutes that include swollen absorbent material separated by distribution zones (14), regions of the composite that are substantially free of absorbent material. Absorbent articles that include the composite are also disclosed.
L'invention porte sur un composite (10) absorbant comportant une matrice fibreuse présentant des bandes (12) de matériau absorbant longitudinales délimitant des zones (14) de répartition du liquide. Au contact du liquide le matériau absorbant gonfle ce qui donne un composite humide cannelé présentant des zones de matériau absorbant séparées par des zones (14) de répartition pratiquement exemptes de matériau absorbant. L'invention porte également sur des articles absorbants incluant ledit composite.
