    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： 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 C. The filaments are also aerodynamically withdrawn by means sufficient to create a filament withdrawal velocity between about 20 meters/second and 60 meters/second.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 These aerodynamically withdrawn filaments are then deposited onto a moving porous support in order to form a continuous web.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： In a carpet capable of being shaped three-dimensionally particularly for use in automobiles, comprising a tufted spun nonwoven fabric backing of polyester reinforced by a binding-fiber content and provided with at least a single-layer back coating of an at least partly thermoplastic material, and tufting through said base, the improvement which comprises constructing the spun nonwoven fabric so that at a temperature of 127.degree. C. it has about 40 to 50%, and at a temperature of 157.degree. C. about 25 to 35%, of its tensile strength at 22.degree. C. and an elongation of about 65 to 100%, but at least a value of about 15 N per cm of width. Advantageously, the carpet includes a back coating of one layer of acrylic resin on the spun nonwoven fabric and a further layer of sintered polyethylene powder on top of the acrylic resin layer.

    摘要： In the manufacture of a shaped automobile carpet in which a spun nonwoven-fabric backing composed of two dissimilar types of polyester filaments is tufted, then provided on its back with a layer of a polymeric dispersion binder, and shaped in heated state, the improvement which comprises bonding to the underside of the carpet before shaping a spun nonwoven fabric having isotropic strength properties and a weight per unit area of about 20 to 60 g/m.sup.2. Advantageously, the spun nonwoven fabric is bonded to the underside by a layer of sintered polyethylene powder. Such carpet shows less spacing than heretofore between the tufts in critical zones of curvature.
