Fireproof fabric and seat

Abstract

A task is to provide a fire-resistant fabric and a seat each having excellent flame retardancy, fire resistance, strength, comfortability, and formability, and a solution to problem is that a fire-resistant fabric which has a bending resistance of 95 mm or less in the warp direction or in the weft direction, as measured by the method prescribed in JIS L 1096 (2010) A method (45° cantilever method), is obtained using a flame-retardant fiber having an LOI of 26 or more, as measured in accordance with JIS L 1091 (1999) E-2 method.

1 . A fire-resistant fabric comprising a flame-retardant fiber having an LOI of 26 or more, as measured in accordance with JIS L 1091 (1999) E-2 method, wherein the fire-resistant fabric has a bending resistance of 95 mm or less in the warp direction or in the weft direction, as measured by the method prescribed in JIS L 1096 (2010) A method (45° cantilever method). 
     
     
         2 . The fire-resistant fabric according to  claim 1 , which has a circular knitted structure. 
     
     
         3 . The fire-resistant fabric according to  claim 1 , which is formed from double knit. 
     
     
         4 . The fire-resistant fabric according to  claim 1 , which contains a meta-aramid fiber and a para-aramid fiber and/or an oxidized polyacrylonitrile fiber as the flame-retardant fiber. 
     
     
         5 . The fire-resistant fabric according to  claim 1 , which has a weight per unit of 400 g/m 2  or less. 
     
     
         6 . The fire-resistant fabric according to  claim 1 , which has an air permeability of 90 cm 3 /cm 2  sec or more. 
     
     
         7 . The fire-resistant fabric according to  claim 1 , which has an elongation of 8% or more, as measured in accordance with JIS 1096 (2010) D method (constant load method) Cut strip method, at a distance between two gage marks: 200 mm, and at a constant load: 4.9 N, and which has a stretch modulus of 70% or more, as measured in accordance with JIS L 1096 (2010) E method (constant load method) Cut strip method, at a constant load: 0.89 N, with repeating loading: once. 
     
     
         8 . The fire-resistant fabric according to  claim 1 , which has a burst strength of 1,000 kPa or more, as measured in accordance with JIS L 1096 (2010) A method (Mullen method). 
     
     
         9 . A seat having the fire-resistant fabric according to  claim 1  sandwiched between face fabric and a cushioning material. 
     
     
         10 . The seat according to  claim 9 , wherein the fire-resistant fabric is fixed to the face fabric by sewing. 
     
     
         11 . The seat according to  claim 9 , which is for use in aircraft, vehicle, rolling stock, vessel, hospital, nursing home, theater, or interior decoration. 
     
     
         12 . The fire-resistant fabric according to  claim 2 , which is formed from double knit.
