Patent number: 7632766Abstract: An insulating fabric which substantially prevents propagation of fire uses a blend of modified aluminum oxide-silica fibers and organic fibers in a multi-layer blanket.Type: GrantFiled: May 4, 2007Date of Patent: December 15, 2009Assignee: Tex Tech Industries, Inc.Inventors: David F. Erb, Jr., Robert A. Gravel, Eric D. Ritter, Eric A. Barter

Patent number: 6900147Abstract: A neckable nonwoven web is provided with a central region and two edge regions, the central region being selectively easier to neck than the two edge regions. The nonwoven fibers in the central region have a polymer composition and/or physical properties which differ from the nonwoven fibers in the two edge regions. The selectively easier necking in the central region causes the central region to neck to about the same extent as the two edge regions, which otherwise would experience greater necking than the central region if the starting nonwoven web were completely uniform. Necked nonwoven webs and neck-bonded laminates made using the improved neckable nonwoven web, are also provided.Type: GrantFiled: November 28, 2001Date of Patent: May 31, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael T. Morman, Charles J. Morell

Publication number: 20040242107Abstract: A non-woven flame blocking fabric and method utilizes a fibrous blend of a concentration of cellulosic organic fibers (A) and a concentration of inorganic fibers (B) to which a flame retardant composition (C) is applied. The concentrations of fibers are blended and treated to form a flame retardant fiber blend capable of forming a non-woven flame blocking fabric that upon exposure to flame forms a reinforced char barrier (D) that prevents the flame from igniting any flammable substrate. The reinforced char barrier (D) includes the carbonized cellulosic organic fibers and melted inorganic fibers. A concentration of binder fibers or powders (E) may alternatively supplement the fiber blend to produce a low profile flame blocker fabric upon activation and calendaring. The fabric preferably has a low profile as a result of compaction and bonding, but the fabric may be provided as a high-loft web.Type: ApplicationFiled: May 30, 2003Publication date: December 2, 2004Inventor: Loren M. Collins

Publication number: 20030207637Abstract: A launderable fluid containment textile composite of stitch bonded construction useful in an incontinence pad. The textile composite includes a fluid retention layer of non-woven fabric formed from a plurality of intermingled textile fibers. A liquid permeable barrier layer of porous fabric is disposed across the fluid retention layer. A plurality of spun yarns including polyester and rayon constituents extend in a repeating stitch bonding pattern through the fluid retention layer and the liquid permeable barrier layer such that the spun yarns form a surface layer over the liquid permeable barrier layer at the technical face of the textile composite. The stitch bonding pattern is characterized by a stitch density in the machine direction of about 4 to about 14 stitches per inch.Type: ApplicationFiled: May 19, 2003Publication date: November 6, 2003Applicant: TIETEX INTERNATIONAL, LTD.Inventor: Martin Wildeman

Publication number: 20030104745Abstract: The present invention is directed a nonwoven fabric which is imparted with a three-dimensional image or pattern during the fabrication stage. The three-dimensional image or pattern imparted into the structure of the nonwoven fabric results in a lofty material with particulate capturing recesses or “pockets” which act to entrap and entrain dust. The three-dimensional image or pattern also results in a number of fibrous ends and loops which extend beyond the surface of the recesses or “pockets”, which in turn, improve the nonwoven fabrics ability to effectively collect particulates from the surface of the article to be cleaned or dusted. In conjunction, the recesses and the extended fibrous surface act to effectively remove fine particulates such as dust from articles such as furniture and flooring.Type: ApplicationFiled: July 26, 2002Publication date: June 5, 2003Applicant: Polymer Group, Inc.Inventor: Charles Keith Curtis

Patent number: 5985442Abstract: A wall lining material consists of an upper mat body, a lower mat body and a granular moisture absorbent. The upper mat body and the lower mat body are made of a nonwoven fabric containing a multiplicity of fibers. The moisture absorbent is located between these two mat bodies. The mat bodies are sewn together over the laminated portion at many points by means of needle punching. This needle punching causes the fibers in the upper mat body to be connected with those in the lower mat wed and vice versa.Type: GrantFiled: June 9, 1997Date of Patent: November 16, 1999Assignee: Maruwa Co., Ltd.Inventor: Megumi Nagaya

Patent number: 5872067Abstract: A needled mat adapted to reinforce a thermoplastic matrix material includes (a) a primary layer having a plurality of thermoplastic fibers in an amount greater than about 20 weight percent of the primary layer on a total solids basis, the primary layer being less than about 20 weight percent of the mat on a total solids basis; and (b) a secondary layer having a plurality of discontinuous glass fiber strands and having thereon a strand coating composition which is compatible with the thermoplastic matrix material, the secondary layer being essentially free of individual glass monofilaments.Type: GrantFiled: March 21, 1997Date of Patent: February 16, 1999Assignee: PPG Industries, Inc.Inventors: Jian Meng, Thomas V. Thimons, Thomas P. Unites

Patent number: 5744408Abstract: An improved article of manufacture and method thereof utilizing a fibrous structure of initially discrete layers, each having first and second sides. At least one side of each layer is rough and the structure has a shrinkage of no more than about 2 percent. The structure is impregnated with a thermoplastic-type polymeric material, and in the final structure there is no visible layer separation.Type: GrantFiled: June 7, 1995Date of Patent: April 28, 1998Inventor: Robert J.
