Abstract

An absorbent body in an absorbent article, such as a sanitary napkin, panty protector, incontinence guard, diaper or the like. The absorbent body includes a first layer, an admission layer (4), which comprises a mixture of 80-95% resilient fibres and 5-20% heat-actuable binding fibres, preferably bicomponent fibres, and a second layer, a storage and dispersion layer (5), which comprises a mixture of 45-90% absorbent fibres and 5-15% heat-actuable binding fibres, wherein the binding fibres are heat treated so as to bond together and to hold the fibre structures together in the first and second layers (4, 5), such that these layers will form a laminate that has a tensile strength of at least 2N/50 mm in a dry state. The absorbent body also has a high surface dryness and low rewetting tendency and exhibits good absorption properties.
