  • Publication number: 20060148360
    Abstract: A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

  • Publication number: 20060105664
    Abstract: A process for making abrasion-resistant composites is disclosed. The process comprises the steps of providing a fibrous sheet containing a high density of relatively short staple fibers having a decitex under 6.6; needle-punching the staple layer and applying an adhesive containing layer; followed by the application of heat and pressure to the composite to form a thin consolidated and abrasion-resistant back-face layer on the composite. Preferably, the adhesive layer is penetrated by the needled fibers during the needling step and the product is shrunk in area by 20-50% before the consolidation step. Also optionally, the consolidated layer is abraded or perforated to create micro-pores that are permeable to gases and capable of containing liquids under low-to-moderate pressures.

  • Publication number: 20050269318
    Abstract: A microwavable package has a pad for absorbing fat, grease, oil, moisture, and like liquid exuded from food, primarily meat, during cooking. The pad has a high-melting, liquid-transmissible, stiff, shrink-resistant, preferably foraminous face layer in contact with the food. A body layer is in contact with the face layer opposite the food. During cooking, the food releases liquid that transfers through the face layer where it contacts and is absorbed by the body layer. The face layer resists adhering to the food and therefore can be easily separated from the food after cooking.

  • Patent number: 6967052
    Abstract: A stitched yarn surface structure includes a backing having decorative upper surface and a thickness dimension T of at least two (2) millimeters. The backing exhibits a predetermined compressive resistance Rb. Plural rows of face yarn segments cover at least a portion of the decorative upper surface of the backing, with adjacent face yarn segments being spaced apart by a predetermined minimum spacing dimension S. The yarns forming the face yarn segments have a predetermined compressive resistance Ry. The compressive resistance Rb, the compressive resistance Ry, and the spacing S are selected such that a load of up to one hundred (100) pounds per square inch (psi) imposed on the stitched yarn surface structure by a loading member is able to be borne by the stitched yarn surface structure without allowing contact between the member and the decorative upper surface of the backing.

  • Publication number: 20050227038
    Abstract: Disclosed herein is a composite comprising at least one heat shrinkable adhesive layer stitch-bonded with yarns, which shrink less than the adhesive layer or do not shrink, when the adhesive layer is exposed to heat. The stitch-bonded yarns form loops upstanding from the shrunk adhesive layer and the loops create a textured surface on the composite, and the composite is substantially inelastic after the adhesive layer is shrunk. The composite may further comprise at least one fibrous layer stitch-bonded to the shrinkable adhesive layer, and the fibrous layer is less shrinkable than the adhesive layer or is substantially non-shrinkable.

  • Publication number: 20050155693
    Abstract: A thermoplastic binder applied in the vicinity of the roots of a pile surface structure, typically before stitching, is raised above its melting point but below the critical exposure temperature that can adversely affect the properties of the material forming the pile elements. While at this elevated temperature the pile surface structure is mechanically flexed, as by repeatedly bending the backing with the pile loops thereon into and out of its plane. This flexing action assists the molten (but not freely flowing) binder to propagate into the roots of the pile elements and into the interstices between the fibers forming the same.

  • Publication number: 20050118912
    Abstract: A stretchable stitch-bonded nonwoven fabric is disclosed herein. The fabric includes a nonwoven substrate having basis weight in the range from about 15 to about 150 g/m2, and density in the range from about 0.02 to about 0.12 g/cm3. The nonwoven substrate is bonded with a binder applied to the outer surfaces of the substrate in a liquid form in a sufficiently uniform manner so that no areas greater than the spaces between stitch insertion points are devoid of binder. The binder constitutes from about 2% to about 25% of the total weight of the sum of binder and nonwoven substrate weight. The substrate is stitch-bonded with yarns arranged in a stitch pattern that allows the stitch-bonded fabric to be stretched in at least one direction by a factor of about 2.5 to about 5.0 without forming local ruptures therein, and wherein the stitch-bonded nonwoven fabric can be washed and dried at least twenty times.
