    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 present invention relates to the use of a polypropylene mixture for the production of a spunbonded non-woven fabric having increased elastic property, wherein the polypropylene mixture substantially comprises a first homopolypropylene and a second homopolypropylene, wherein an MFR of the first homopolypropylene is greater than an MFR of the second homopolypropylene, wherein the second homopolypropylene has a weight proportion in the polypropylene mixture of at least 3% by weight to a maximum of 25% by weight, wherein the first homopolypropylene is substantially the remaining weight proportion of the polypropylene mixture, wherein the second homopolypropylene has an MFR between 0.7 and 14 g/10 min (230° C./2.16 kg) according to ISO 1133, and a difference of the MFR of the second homopolypropylene to the MFR of the first homopolypropylene is at least 10 g/10 min, and an upper limit of the MFR of the first homopolypropylene is 55 g/10 min (230° C./2.16 kg) according to ISO 1133. Substantially here shall mean that only the two homopolypropylenes are used as polymers. Additionally, additives can be added, but no further polymer. The invention further relates to a corresponding polypropylene mixture, a spunbonded non-woven fabric made from said polypropylene mixture, and a corresponding method of production.
