Experimental determination and interpretation of absorption capacities of liquids by biotextiles with complex absorbent structure - Influence of superabsorbent polymer gels

The disposable diapers are materials with heterogeneous structure organized by a fibrous cellulosic support and a reinforcement of a superabsorptive p olymer (SAP) profile. In this study, we are interested to: modes of use of these absorbent materials, specially scattering techniques of SAP polymer in the absorbent core; their physical and chemical properties such as absorption capacity or fluid transport mechanisms. In laboratory samples we led absorption, retention and wet-back tests with a standard liquids (deionized water and physiological saline solution). The analysis of results reveal absorption capacities of these biotextiles, the improvement of their characteristics is conditioned by the superabsorptive polymer. (C) 2001 Elsevier Science B.V.
