  • Patent number: 7972675
    Abstract: A friction material has a resin amount distribution that is the largest at a portion near a non-friction surface, that becomes lower toward an inside and that is the lowest at a portion near a friction surface. For example, such friction material is manufacture as follows. First, two friction materials are overlapped while the friction surfaces faced with each other. Then, the friction materials are dried at a room temperature. At this time, the resin has such a characteristic as to move while dragged by a solvent that dries from the non-friction surface located outside. Using such characteristic, the resin amount at the portion near the friction surface is lessened. Then, a temperature at the friction surface is made low and a temperature at the non-friction surface is made high in a drying step of the friction material. Thereby, the resin amount at the portion near the friction surface is lessened.

More particularly, the method includes bonding a layer of non-woven fibers and a layer of re-bonded foam particles together to form the bi-layered carpet underlay. The layers of the carpet underlay can be bonded together with the use of adhesives, by heating a surface of one or both layers to a soft bondable state for lamination between the layers, by applying a film having adhesive surfaces between the layers, or by other suitable bonding means. The bi-layered carpet underlay combines the soft cushioning resilience of foam with the high durability bridging ability of fiber to provide a carpet underlay that maintains its height or thickness and firmness, while imparting softness and cushioning effects over an extended period of wear.

  • Patent number: 7638446
    Abstract: The present invention is directed to a hydroentangled flame retardant nonwoven fabric, and more specifically, to a cellulosic flame retardant fabric comprising a self extinguishing fiber so as to minimize the total percentage of fabric weight lost upon burning in accordance with technical bulletin 604. Use of natural fiber fabrics in bedding components is desirable due to the softness and durability associated with the fabrics; however, natural fiber, such as cellulose, is highly flammable and therefore lacks the ability to provide the proper flammability protection often sought out in bedding components. In accordance with the present invention, a small amount of self-extinguishing fiber, such as a modacrylic fiber, was blended with the natural fiber and hydroentangled to form a nonwoven composite fabric that is soft, flame retardant, and suitable for bedding articles.

  • Patent number: 7608125
    Abstract: Wet laid, nonwoven, fibrous mats suitable for making MERV 6 or higher filters, and methods of making the nonwoven mats are disclosed. The mats include a blend comprising a major portion of glass fibers and a minor portion of man-made polymer fibers, such as polyester fibers, the fibers being bound together with a cured binder having a Tg in the range of about minus 30 to about 50 degrees C. The mats are pleated prior to assembling the filter in conventional manner. The only fibrous mat in the filters is wet laid fibrous nonwoven mat and the pleated filter media needs no other means of support in the filter frame.

  • Patent number: 7605097
    Abstract: A unitary, fiber-containing composite comprises (a) a first region comprising a plurality of first binder fibers and a plurality of bast fibers, (b) a second region disposed above the first region, the second region comprising a plurality of second binder fibers and a plurality of bast fibers, and (c) a transitional region disposed between the first region and the second region. The transitional region comprises concentrations of the first binder fiber, the second binder fiber, and the bast fiber. The concentration of the first binder fiber in the first transitional region is greatest proximate to the first region and least proximate to the second region, and the concentration of the second binder fiber and the bast fiber in the first transitional region is greatest proximate to the second region and least proximate to the first region. A method for producing a unitary, fiber-containing composite is also described.

  • Patent number: 7582132
    Abstract: Wet laid, nonwoven, fibrous mats suitable for making MERV 6 or higher, filters, and methods of making the nonwoven mats filter media are disclosed. The mats include a blend comprising a major portion of glass fibers, a minor portion of man-made polymer fibers, such as polyester fibers and about 0-30 wt. percent of chemically cross linked bleached Kraft pulp the fibers, and optionally fully bleached softwood Kraft pulp, the fibers being bound together with a cured binder having a Tg in the range of about minus 30 to about 50 degrees C. The mats are pleated prior to assembling the filter in conventional manner. The only fibrous mat in the filters is wet laid fibrous nonwoven mat and the pleated filter media needs no other means of support in the filter frame.

  • Patent number: 7517821
    Abstract: An automobile interior board includes a base layer; and a nonwoven or woven surface layer, laminated on at least one surface of the base layer. The base layer is comprised of a composite material of: a first fiber, comprised of a bamboo fiber; a second fiber, comprised of one of cotton, hemp and mixture of cotton and hemp; and a biodegradable resin. Weight percentage of the first fiber, the second fiber and the biodegradable resin satisfies a following equation, the first fiber: the second fiber: the biodegradable resin=30 to 70:10 to 60:20 to 60. The surface layer is comprised of one of a PET resin fiber and a natural material-derived fiber.
