    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.

    摘要: Disclosed are bicomponent fibers with aliphatic polyester forming a first component and a polyolefin forming a second component wherein the polyolefin contains an adjuvant improving the biodegradability of said polyolefin. Textile sheets comprising these bicomponent fibers are comparable in their mechanical properties to polyolefin based textile sheets while these are more efficiently decomposed by the action of microorganisms as polyolefin based textile sheets.
