A laminate material comprising a first liquid-permeable material layer, a plurality of discretely-arranged material pieces of a second liquid-permeable material and a second liquid-permeable material layer,
- wherein the first material layer and the discrete material pieces are internally joined in discrete bonding sites,
- wherein the discretely-arranged material pieces are arranged between the first liquid-permeable material layer and the second liquid-permeable material layer,
- wherein the second material layer is joined to the first liquid-permeable material layer and the discretely-arranged material pieces in said discrete bonding sites,
- wherein at least part of the two liquid-permeable material layers and/or the discretely-arranged material pieces comprises thermoplastic material, whereby the thermoplastic material has been made at least partly to soften or melt and thereby bind together the two material layers and the material pieces discretely arranged therebetween,
- wherein the discrete material pieces are arranged at a distance from each other in the longitudinal direction of the laminate material,
- wherein the first liquid-permeable material layer comprises a nonwoven material,
- wherein the second liquid-permeable material layer comprises a nonwoven material.
