CA 2254074

The invention refers to methods for assessing absorbent structures (10) for their fluid handling ability by using materials (110) having a moisture pick up ability which is very close to the one of human skin. This is achieved by using materials (110) which do not function based on capillary transport for moisture, but which comprise as an essential element swellable but non-soluble materials in a film form. Such materials (110) can be based on proteins, Glycin, Prolin, 4- hydroxyprolin, naturally occurring sugars, glycerin, sorbit and collagen. A particularly preferred material is a film material comprising collagen. To simulate a baby's weight upon the absorbent structure (10), a load (16) may be utilized therewith.

Cette invention se rapporte à des procédés d'évaluation des caractéristiques de structures absorbantes (10) et notamment de leur capacité de rétention des fluides, lesdits procédés consistant à utiliser des matières (110) ayant une capacité d'absorption de l'humidité qui est très proche de celle de la peau humaine. Les matières utilisées (110) sont des matières qui ne fonctionnent pas sur la base d'un transport capillaire de l'humidité, mais qui comportent en tant qu'élément principal des matières non solubles mais susceptibles de gonfler et se présentant sous forme pelliculaire. Ces matières (110) peuvent être constituées de protéines, de Glycine, de Proline, de 4-hydroxyproline, de sucres d'origine naturelle, de glycérine, de sorbite et de collagène. Une matière particulièrement préférée est une matière se présentant sous forme pelliculaire et comportant du collagène. De manière à simuler le poids du bébé sur la structure absorbante (10), on peut placer une charge (16) sur ladite structure.
