Abstract:
(EN) The present invention relates to substituted cellulose acetates and methods of use thereof. One embodiment of the present invention provides a diaper having an inner layer having an absorbent core having a substituted cellulose acetate having a polar substituent that has an oxygen atom covalently bonded to a nonmetal selected from the group of sulfur, phosphorus, boron, and chlorine; wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate; and an outer layer.
(FR) L'invention concerne des acétates de cellulose substitués et leurs méthodes d'utilisation. On décrit, dans un mode de réalisation de l'invention, une couche-culotte qui comprend: une couche extérieure; et une couche intérieure à âme absorbante comprenant un acétate de cellulose substitué dont un substituant polaire comprend un atome d'oxygène lié de manière covalente à un élément non métallique choisi dans le groupe du soufre, du phosphore, du bore et du chlore, l'élément non métallique étant présent dans une proportion d'au moins environ 0,01% en poids de l'acétate de cellulose substitué.
