  • Patent number: 11118289
    Abstract: A flame-blocking nonwoven fabric has excellent processability and high flame-blocking properties. The flame-blocking nonwoven fabric has a density of 200 kg/m3 or more and includes non-melting fibers A whose high-temperature shrinkage rate is 3% or less and whose Young's modulus multiplied by the cross-sectional area of the fibers is 2.0 N or less, and thermoplastic fibers B whose LOI value is 25 or more as determined according to JIS K 7201-2 (2007).
    Type: Grant
    Filed: June 28, 2016
    Date of Patent: September 14, 2021

  • Publication number: 20190242037
    Abstract: A sliding fabric exhibits a small amount of compression in the thickness direction under load application, does not cause generation of play between members, and is superior in sliding properties and durability. The sliding fabric is configured such that fluororesin fibers (X) and other fibers (Y) are alternately arranged as warps and/or wefts on at least one side of the fabric and the amount of compression of the fabric is 25 ?m or less.

  • Patent number: 9962912
    Abstract: A composite sliding member includes a combination of a fiber woven fabric and a resin member, wherein the fiber woven fabric is a multilayer woven fabric having a front surface layer serving as a sliding surface and a rear surface layer adhered to the resin member, the front surface layer mainly including a fluororesin fiber and the rear surface layer mainly including a heat resistant fiber; wherein when a cross section of the composite sliding member crossing the fiber woven fabric, the resin member, and their composite interface is observed, one heat resistant fiber A of such heat resistant fiber at a position adjacent to the resin member with no intervening other fiber in the cross section is observed, and a ratio of a number of monofilaments in the heat resistant fiber A not in close contact with the resin constituting the resin member or adjacent monofilaments in relation to a number of all monofilaments constituting the heat resistant fiber A is R1, and R1 is 0 to 70%.

  • Publication number: 20160341244
    Abstract: A curved sliding unit has stable sliding performance and long service life. The curved sliding liner in a bowl shape obtained by rolling a ribbon-shaped woven cloth forms steps in the width direction of the ribbon. A curved sliding unit includes an external member, the curved sliding liner disposed inside the external member, and an internal member disposed inside the curved sliding liner.

  • Publication number: 20160320732
    Abstract: A low-friction sliding material includes a sliding member having a sliding surface, and a fluorine fiber or a fluorine fiber-containing composite fiber disposed in parallel at least on the outermost part of the sliding surface in a direction substantially the same as a sliding direction and covers 60% or more of the sliding surface. A low-friction sliding material is free from the occurrence of fabric separation or other defects in an extremely easy manner.
