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.

[ What is claimed is:] [1.] A method for assessing disposable absorbent structures for their fluid handling ability whereby the performance of the absorbent structure is assessed by the amount of fluid this structure releases to a pick up material after the structure has been loaded with a test liquid,said method comprising the steps of:a) providing said absorbent structure;b) loading said absorbent structure with said test liquid;c) providing said pick up material and preweighing said pick up material to determine an initial weight;d) positioning said pick up material on said absorbent structure for a predetermined time under a predetermined pressure such that said absorbent structure releases a portion of said test liquid to said pick up material to load said pick up material;e) removing said loaded pickup material from said absorbent structure;f) weighing said loaded pick up material to determine a loaded weight: andg) calculating a Skin Hydration Value by subtracting said initial weight from said loaded weightwherein said pick up material consists essentially of material swellable and insoluble in water; and in that the fluid transfer to the moisture pick up material is dominated by hydration mechanisms.
