Abstract
Official abstract text for this publication.
A flame resistant woven fabric has a thickness of 0.08 mm or more in accordance with the method of JIS L 1096-A (2010) and including warps and wefts, the warp and the weft each comprising: a non-melting fiber A having a high-temperature shrinkage rate of 3% or less; and a thermoplastic fiber B having an LOI value of 25 or more in accordance with JIS K 7201-2 (2007) and having a melting point lower than the ignition temperature of the non-melting fiber A; wherein the warp and the weft each have a fracture elongation of 5% or more; and wherein, in the projection area of the weave repeat of the flame resistant woven fabric, the area ratio of the non-melting fiber A is 10% or more and the area ratio of the thermoplastic fiber B is 5% or more.
First claim
Opening claim text (preview).
The invention claimed is: 1. A flame resistant woven fabric having a thickness of 0.08 mm or more determined in accordance with JIS L 1096-A (2010) and consisting of warps and wefts, each comprising: a non-melting fiber A having a high-temperature shrinkage rate of 3% or less; and a thermoplastic fiber B having an LOI value of 25 or more determined in accordance with JIS K 7201-2 (2007) and having a melting point lower than an ignition temperature of said non-melting fiber A; wherein 1) said warp and said weft each have a fracture elongation of more than 5%; 2) in a projection area of a weave repeat of said flame resistant woven fabric, an area ratio of said non-melting fiber A is 10% or more and an area ratio of said thermoplastic fiber B is 5% or more, and 3) said non-melting fiber A is a flame resistant fiber, and 4) said thermoplastic fiber B is a fiber composed of polyphenylene sulfide. 2. The flame resistant woven fabric according to claim 1 , further comprising a fiber C other than said non-melting fiber A and said thermoplastic fiber B, wherein, in the projection area of the weave repeat of said flame resistant woven fabric, an area ratio of said fiber C is 20% or less.
