An absorbent product comprising a liquid-permeable casing layer ( ), a liquid-barrier layer ( ) and an absorption element ( ) which is enclosed between the liquid-permeable casing layer ( ) and the liquid-barrier layer ( ), and a liquid-transfer layer ( ) which is disposed between the liquid-permeable casing layer ( ) and the absorption element ( ). The envelope layer ( ) is bonded in a pattern of distinct thermally produced bonds ( ) to the liquid-transfer layer ( ). The liquid-transfer layer ( ) comprises 40-65% by weight network-creating function fibres which are substantially intact following the bonding-together of the envelope layer ( ) and the liquid-transfer layer ( ) and which have a fibre coarseness ranging from 6 denier to 12 denier and 35-60% by weight fibres comprising a weldable, thermoplastic component and having a fibre coarseness of at least 3 denier.
