Patent number: 6692825Abstract: A nonwoven web and method of preparing a novel nonwoven web of synthetic fiber are disclosed. An aqueous solution amide crosslinked synthetic precursor polymer is extruded under defined conditions through a plurality of die orifices to form a plurality of threadlines. The threadlines are attenuated with a defined primary gaseous source to form fiber under conditions of controlled macro scale turbulence and under conditions sufficient to permit the viscosity of each threadline, as it leaves a die orifice and for a distance of no more than about 8 cm, to increase incrementally with increasing distance from the die, while substantially maintaining uniformity of viscosity in the radial direction, at a rate sufficient to provide fiber having the desired attenuation and mean fiber diameter without significant fiber breakage. The attenuated threadlines are dried with a defined secondary gaseous source. The resulting fibers are deposited randomly on a moving foraminous surface to form a substantially uniform web.Type: GrantFiled: March 6, 2002Date of Patent: February 17, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jian Qin, Yong Li, Wendy Lynn Van Dyke, Anthony John Wisneski, Palani Raj Ramaswami Wallajapet, Hannong Rhim

Publication number: 20040023585Abstract: A flexible, vapor permeable, liquid impermeable composite fabric comprising a ultraviolet light stabilized and thermally stabilized microporous-formable polyolefin barrier layer extrusion laminated to an ultra-violet light stabilized and thermally stabilized polyolefin nonwoven fabric, the composite of which has been incrementally stretched to induce sufficient moisture vapor transmission characteristics while maintaining adequate resistance to water penetration, and methods of making the composite. This composite may be further laminated to one or more layers of either woven or nonwoven materials offering strength and environmental resistance characteristics sufficient for various outdoor applications including covers and building construction products. Embodiments of the above mentioned components have been shown to offer improved liquid resistance, environmental stability, and abrasion resistance as compared to existing commercially available materials.Type: ApplicationFiled: June 19, 2002Publication date: February 5, 2004Inventors: Todd R.

Patent number: 6656856Abstract: The present invention relates to mattress or furniture insulator pads that are placed between the coil springs and the cushioning material in mattresses or furniture, such as chair seats. Such insulator pads prevent the springs from piercing the furniture cushion and provide a bridge across the springs to more evenly distribute weight over the springs. The insulator pads according to the invention have three layers formed by sandwiching polyurethane foam between stiffening layers, preferably formed from polypropylene openmesh netting. Most preferably, a five layer insulator pad has the polyurethane foam sandwiched between stiffening layers and also has outer layers of polyurethane foam, applied adjacent to the stiffening layers, forming the top and bottom surfaces of the pad. Such outer layer foam sheets provide friction characteristics that retard relative movement between the cushion and the springs.Type: GrantFiled: September 21, 1998Date of Patent: December 2, 2003Assignee: Foamex L.P.Inventor: John R.

Publication number: 20030215618Abstract: A laminated fabric floor product having an encapsulated fabric scrim within a vinyl resilient flooring structure. The laminated fabric floor product structure includes a PVC calendered base, a first hot melt film, a fabric, a second hot melt film, a calendered clear film, and a high performance coating. Traditional foamed and non-foamed substrates used in the flooring industry can be used in addition to the calendered base. All types of fabrics and scrims can be encapsulated. The fabrics can be both woven and non-woven types. Open scrims can be used with base layers that are printed or have a visual pattern so that design features and colors can be seen through the open areas of the scrim. The fabric layer can be printed with a design pattern and adhered to the base layer or substrate by the first hot melt adhesive film layer. The clear layer is adhered to the fabric layer by the second hot melt adhesive layer.Type: ApplicationFiled: May 14, 2002Publication date: November 20, 2003Inventors: Steven F. Hynicka, Donald E. Barshinger, Donald E. Schneider

Resin-impregnated belt for application on papermaking machines and in similar industrial application
Patent number: RE39176Abstract: A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has a base fabric in the form of an endless loop with an inner surface, an outer surface, a machine direction and a cross-machine direction. The base fabric has machine-direction (MD) structural elements and cross-machine-direction (CD) structural elements in an open structure wherein at least some of the MD structural elements and CD structural elements are spaced apart from one another. The MD structural elements cross the CD structural elements at a plurality of crossing points, where they are joined to one another by mechanical, chemical or thermo-bonding means. A coating of a first polymeric resin is on the inner surface of the base fabric. The first polymeric resin impregnates and renders the base fabric impermeable to liquids, and forms a layer on the inner surface thereof. The coating is smooth and provides the belt with a uniform thickness.Type: GrantFiled: January 15, 2003Date of Patent: July 11, 2006Assignee: Albany International Corp.Inventor: William H. Dutt
