    摘要： A spunbonded fabric of nylon 6, bonded by binders such as polyacrylates and polyurethanes, in which the filaments are substantially in the .gamma.-modification in the crystalline regions and the average molecular orientation, produced by attenuation, of the nylon 6 filaments is at most 80% of the theoretically possible orientation. It is an object of the invention to produce spunbonded fabrics of improved properties and to do so more economically, e.g. with higher outputs.

    摘要： The present invention provides a method for manufacturing polypropylene spun-bonded fabrics, which method involves preparing a polypropylene melt at a temperature of about 240.degree. to 280.degree. C. and forming polypropylene filaments by extruding this melt through a spinning nozzle at an extrusion velocity of about 0.02 meter/second to 0.2 meter/second. The spinning nozzle, or spinneret, has holes with a diameter less than 0.8 millimeter. The filaments thus formed are subsequently quenched by transversely blowing air at a temperature between about 20.degree. to 40.degree. C. The filaments are also aerodynamically withdrawn by means sufficient to create a filament withdrawal velocity between about 20 meters/second and 60 meters/second. The ratio of the extrusion velocity to the withdrawal velocity (herein defined as the deformation ratio) is between about 1:200 and 1:1000. These aerodynamically withdrawn filaments are then deposited onto a moving porous support in order to form a continuous web. This web is then bonded by suitable means, forming a finished spun-bonded nonwoven fabric.

    摘要： A spun nonwoven fabric of polyester filaments for use as backing for a deep-drawable tufted carpet, wherein the polyester filaments hve uniformly distributed therethrough about 0.1 to 1% by weight of a diol-modified copolyester containing units of at least two different doils. For example, polyethylene terephthalate granulate is mixed with polyethylene butylene terephthalate copolymer and spun into a nonwoven web which is calendered and then tufted to form a carpet which can be deep-drawn with a three-dimensional shape. If desired, polyethylene terephthalte-adipate copolymer fibers can be co-spun into the web as binding fibers.

    摘要： A nuclear magnetic resonance tomography apparatus has a magnet assembly with a first surface and a gradient coil assembly with a second surface, with an annular gap between these surfaces. A noise-reduction arrangement for damping the oscillations of the gradient coil assembly and/or for stiffening the gradient coil assembly is disposed in this gap in contact with the first and second surfaces. The noise-reducing arrangement can be composed of one or more components, and has contact surfaces, formed by one or more components, respectively in substantially surface-wide contact with the first and second surfaces of the tomography apparatus.

    摘要： For the production of spunbonded fabrics there is given a process consisting in that monocomponent or bicomponent fibers are spun from multiline longitudinal spinning nozzles mounted in rows on double spinning beams in such a way that the emerging filament rovings overlap over the entire production width, that, before depositing, the filament rovings are cooled by transverse blowing from one side and by sucking-off on their other side freed from spinning vapors, mechanically and/or aerodynamically stretched and deposited to the web.The apparatus described comprises double spinning beams with a length of 800 to 8,000 mm which carry multiline longitudinal spinning nozzles staggered to one another with high hole numbers, with lengths of the individual nozzles from 500 to 700 mm.
