    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 C. The filaments are also aerodynamically withdrawn by means sufficient to create a filament withdrawal velocity between about 20 meters/second and 60 meters/second.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 These aerodynamically withdrawn filaments are then deposited onto a moving porous support in order to form a continuous web.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.
