A novel absorbent structure is disclosed in which an initially flat, dense structure becomes a three-dimensional, high bulk, channeled structure upon wetting. The structure offers unusually high directionality in fluid transport to improve the distribution of fluid in longitudinal articles. The self- bulking of the wetted article can also lead to improved fit in articles such as diapers and in general increases the void volume of the wetted article for high absorbent capacity.
L'invention concerne une nouvelle structure absorbante dans laquelle une structure dense, à l'origine plane, se transforme, une fois mouillée, en une structure cannelée gonflante tridimensionnelle. La structure présente une capacité d'orientation exceptionnellement élevée pour le transport des fluides, ce qui favorise le transport de ces derniers dans les articles longitudinaux. Le gonflement spontané de l'article mouillé lui permet également de mieux s'adapter à des articles tels que des couches et, de manière générale, augmente le volume vide de l'article mouillé, lui donnant une capacité d'absorption élevée.
