摘要:
The invention relates to a fibrous porous fluid absorbent material comprising a nonwoven, in particular made by an Airlaid process and comprising fibers at least 50% of said fibers being cellulosic fibers. The fibrous porous fluid absorbent material comprises a core wherein said fibers of said core are non-connected or only partially connected and crosslinked with each other and at least one perforated surface layer having a perforation. The fibers of the surface layer are connected to each other and the flexural rigidity of said fibrous porous fluid absorbent material measured according to EDANA Standard Test Method 90.5 is reduced by at least 20%, preferably by at least 30%, more preferably by at least 40%, most preferably by at least 50%, compared to a corresponding non perforated fibrous porous fluid absorbent material comprising a core and a non perforated surface layer.
