  • Patent number: 10806641
    Abstract: An absorbent structure comprising a planar substrate, an auxiliary glue applied on the substrate, an absorbent material comprising from 80% to 100% by weight of superabsorbent particles deposited on the substrate on an absorbent material deposition area comprising a pattern of absorbent material land areas separated by absorbent material-free junction areas, wherein the deposition area can be notionally divided in eight deposition zones of equal length along the longitudinal direction. A fibrous thermoplastic adhesive layer immobilizes at least some of the absorbent material. The absorbent material is profiled along the longitudinal direction so that at least one of the eight deposition zones is a zone of lower absorbent material amount and the auxiliary glue is absent, or present at a level of at least 50% by weight lower than the average amount of auxiliary glue in at least one of these zones of lower absorbent material amount.
