SHEET, MEMBRANE CEILING, LIGHT MEMBRANE CEILING
To provide a sheet that is excellent in non-combustibility even when using a fiber not flame-retardant treated or containing a small amount of flame retardant, and that can improve, maintenance property of nonwoven fabric Japanese paper tone appearance, and achieve reduction in brightness unevenness and lamp image expression.SOLUTION: There is provided a sheet, which is a sheet that at least comprises a glass fiber cloth and a nonwoven cloth attached to one face of the glass fiber cloth, and in which the sheet has an organic mass of 80 g/m2 or less, the sheet has a ratio of the mass (g/m2) of the glass fiber cloth to the mass (g/m2) of the sheet of 70 to 81 mass%, and the nonwoven cloth has a mass of 30 g/m2 or greater.SELECTED DRAWING: Figure 1
【課題】 難燃化処理されていない、又は難燃剤の含有量が少ない繊維を用いた場合にも不燃性に優れ、不織布和紙調外観維持性の向上、並びに、明るさムラ及びランプイメージ発現の低減、を図ることが可能な、シートの提供を主な課題とする。【解決手段】 少なくとも、ガラス繊維織物と、前記ガラス繊維織物の一方の面に貼付された不織布と、を含むシートであって、前記シートの有機質量が８０ｇ／ｍ２以下であり、前記シートの質量（ｇ／ｍ２）に対する前記ガラス繊維織物の質量（ｇ／ｍ２）の割合が７０～８１質量％であり、前記不織布の質量が３０ｇ／ｍ２以上である、シート。【選択図】 図１
