Meltfusion bonded absorbant structure comprising fibres and superabsorbant particles method for manufacturing such structure

A method for the manufacture of an absorbent structure,

• said structure comprising
• fibres forming a fibrous matrix having an x-, y-, and thickness or z-extension;
• superabsorbent polymer (SAP) particles which are capable of exerting an expansion force upon swelling upon absorption of a liquid and which are positioned within the pores of said fibrous matrix;
• at least one cover web,
• and meltfusion bond points arranged in an x-y-directionally extending bonding pattern, penetrating z-directionally through said fibrous matrix,
• said method comprising the steps of
• providing a fibrous matrix;
• providing SAP particles;
• positioning said SAP particles in interfibre pores of said matrix at a basis weight of not less that about 50 g/m2;
• providing at least one cover web;
• providing a support structure;
• positioning said fibrous matrix with said SAP particles and said at least one cover web positioned parallel to both x-y-directionally extending surface of said structure on said support structure;
• applying energy to said structure to form meltfusion points in a predetermined pattern determined by said support structure,
• wherein said meltfusion points connect said cover web positioned on both surfaces of said structure and exhibit an aspect ratio of their long axis to their short axis of at least 1.05 to 1 and wherein said meltfusion bonds are essentially free of particulate SAP.
