    摘要： The present invention is an absorbent core that may be incorporated into absorbent hygiene articles, such as baby diapers, adult incontinence or feminine hygiene articles. It is particularly suited for articles which are intended to receive more than one liquid gush load, as the absorbent core comprises a fluid distribution layer that comprises sub-layers comprising particular ratios of multicomponent binder fibers, cross-linked cellulose fiber and/or treated or untreated cellulosic fibers.

    摘要： A delivery device for feeding planar material webs, for example airlaids, wetlaids, non-wovens, or films/foils, to a processing installation is proposed, said delivery device having a splicing unit and a multiple-web unwinding device. The splicing unit is configured for connecting a fibrous-web end of a preceding individual fibrous web to a fibrous-web lead of a subsequent individual fibrous web, so as to in this way feed a non-interrupted fibrous web to the processing installation. The splicing unit is moreover configured for processing airlaid fibrous webs that are wound on winding cores and are thus made up as roll goods. The multiple-web unwinding device has at least two winding-core mounts that are capable of being loaded in a mutually independent manner. Each of the winding-core mounts may receive a plurality of comparatively narrow rolls having narrower individual fibrous webs, or alternatively also a comparatively wider roll having a wider multiple fibrous web that is perforated in the unwinding direction. By virtue of the perforation, the wider multiple fibrous web may be detached so as to form a plurality of individual fibrous webs by severing along the perforation, such that as a result narrow fibrous webs may likewise be fed to the splicing unit, as is possible in the case of correspondingly narrow rolls having narrower individual fibrous webs.

    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.
