ABSTRACT:
A composite flat structure having a high degree of absorption for medical and hygiene purposes, the structure comprising at least two layers having differing moisture absorption characteristics. One of the layers is a cover layer comprised of a composite synthetic bonding agent-free non-woven fibre and another of the layers is a storage layer located below the cover layer. The storage layer has a higher degree of moisture absorption than the cover layer which has such a degree of moisture absorption that, after adaptation to normal climate in accordance with DIN 53 802, it has a moisture content of less than 6% relative to its dry weight in accordance with DIN 53 800. The surface of the fibres of the cover layer is capable of being wetted by the liquids to be absorbed.
