Disclosed is an absorbent structure comprising a microbial polysaccharide having improved porosity and a process of making the same. The absorbent structure may be adapted for use in an absorbent product such as a diaper or incontinence product. The process involves the supercritical drying of a microbial polysaccharide to remove at least a portion of the aqueous medium in which the microbial polysaccharide is produced without unacceptably reducing the porosity of the microbial polysaccharide.
On présente une structure absorbante contenant un polysaccharide microbien ayant une porosité améliorée et un procédé de fabrication de celui-ci. La structure absorbante peut être conçu pour être utilisé dans un produit absorbant tel qu'une couche ou un produit pour l'incontinence. Le procédé comprend le séchage supercritique de polysaccharide microbien pour éliminer au moins une partie du milieu aqueux dans lequel le polysaccharide microbien est produit sans réduction inacceptable de la porosité du polysaccharide microbien.
