Abstract
A nonwoven fabric sheet exhibiting high flame shielding performance, heat insulating property, and wear resistance is described, where the nonwoven fabric sheet is fabricated and includes at least one fire barrier layer formed of a web containing a non-melting fiber A having a high-temperature shrinkage rate of 3% or less and a thermal conductivity conforming to ISO22007-3 (2008) of 0.060 W/m·K or less and in which the fire barrier layer is coupled with a scrim layer containing a carbide-forming heat resistant fiber B having a LOI value conforming to JIS K 7201-2 (2007) of 25 or more.
