    摘要： The present invention concerns a nonwoven fabric the fibers of which have polyethylene on at least part of their surface, where the fibers are thermally bonded and the non-woven fabric exhibits an abrasion of less than 0.5 mg/cm2, in particular of less than 0.4 mg/cm2, and an embossed area fraction of less than 35%, in particular of less than 28%. Furthermore a device is made available for the manufacture of a non-woven fabric, using a polyethylene-containing polymer, with a take-down system underneath a spinning plate that causes the take-down of the polyethylene, where the spinning plate has an L/D ratio of between 4 and 9.

    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.
