Abstract: This invention relates to a thin reinforced nonwoven fabric having ridges and grooves for fire blocking an article and articles containing such fabrics. When exposed to heat or flame, the fabric is capable of increasing to a thickness that is at least 1.5 times its original thickness. The fabric comprises an open mesh scrim having a having crimped, heat-resistant organic fibers compressed thereon and held in a compressed state by a thermoplastic binder, on which is imparted a ridge and groove structure. When subjected to high heat or flame, the binder in the structure softens, releasing the restrained crimped fibers and any ridges and grooves and allowing the thickness of the fabric to increase.
Abstract translation: 本发明涉及具有用于阻挡物品的隆起和凹槽的薄增强无纺织物和含有这种织物的制品。 当暴露于热或火焰时，织物能够增加到其原始厚度的至少1.5倍的厚度。 该织物包括开式筛网稀松布，其具有压缩在其上的卷曲的耐热有机纤维，并通过热塑性粘合剂保持在压缩状态，在其上赋予脊和沟槽结构。 当受到高热或火焰时，结构中的粘合剂软化，释放受约束的卷曲纤维和任何脊和槽，并允许织物的厚度增加。
