20080293886 | Use Of Amphiphilic Block Copolymers For Producing Polymer Blends - Production of polymer blends using amphiphilic block copolymers which comprise poly-isobutene blocks and also polyoxyalkylene blocks, as compatibilizers. | 11-27-2008 |
20090104831 | POLYMER FIBER AND NONWOVEN - A polymer fiber comprising a thermoplastic polymer and an inorganic filler, wherein the filler content, based on the polymer fiber, is more than about 10% by weight and the mean particle size (D | 04-23-2009 |
20090233073 | LIGHTWEIGHT SPUN-BONDED NON-WOVEN WITH PARTICULAR MECHANICAL PROPERTIES - Disclosed is a spunbonded non-woven made of polyolefin filaments having a titer <1.6 dtex, the spunbonded non-woven having a surface weight ≦20 g/m | 09-17-2009 |
20090233510 | LIGHTWEIGHT SPUN-BONDED NONWOVEN FABRIC HAVING SPECIAL BARRIER PROPERTIES - The invention relates to a spun-bonded nonwoven fabric made of polyolefin filaments having a titer <1.6 dtex, the spun-bonded nonwoven fabric having a basis weight ≦18 g/m | 09-17-2009 |
20100228214 | Polypropylene mixture - 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. | 09-09-2010 |
