Patent

CA 2384508

An absorbent material (20, 300, 400, 520) is provided with improved characteristics. A process is provided for making the absorbent material. A web is formed with at least one layer of absorbent material, and it may include a mixture of cellulosic fibers (32, 532) and superabsorbent material (40, 540). The moisture content of the web is increased so as to increase the web density. Then, the web is compacted at an elevated temperature to further increase the web density and preferably to also effect hydrogen bonding within the web. In one embodiment a tissue layer (22, 522) is provided, is wetted with water, and is bonded to the layer of absorbent material.

L'invention concerne un matériau absorbant (20, 300, 400, 520) à caractéristiques améliorées, et un procédé de fabrication dudit matériau absorbant. Une bande est formée à l'aide d'au moins une couche de matériau absorbant, et peut comprendre un mélange de fibres cellulosiques (32, 532) et un matériau superabsorbant (40, 540). La teneur en eau de la bande est augmentée, de façon à augmenter la densité de ladite bande. Puis, la bande est compactée à une température élevée de façon à également augmenter la densité de la bande, et effectuer, de préférence, une liaison hydrogène dans ladite bande. Selon un mode de réalisation, une couche de tissu (22, 522) est mouillé avec de l'eau, et est liée à la couche de matériau absorbant.
