LAMINATED SHEET
To provide a laminated sheet which has waterproofness with a simple structure, is not sticky thereon, and is not slippy.SOLUTION: A laminated sheet is obtained by laminating a fiber layer formed of a laminated non-woven cloth obtained by laminating a plurality of non-woven cloths containing a melt-blown non-woven cloth and a span bond non-woven fabric on at least one surface of a waterproof layer containing asphalt, and laminating a resin layer containing a (meth)acrylic resin on the fiber layer. In the laminated sheet, a weather-resistant layer containing inorganic particles may be further laminated on the resin layer. A basis weight of the fiber layer may be 30 g/mor less. A bulk density of the fiber layer may be 10-100 kg/m. The fiber layer may be a laminated non-woven fabric obtained by laminating a span bond non-woven fabric on both surfaces of the melt-blown non-woven cloth. The fiber layer may be a laminated non-woven cloth having a plurality of embossed recesses. The laminated sheet may be a roof underlayment material.SELECTED DRAWING: None
【課題】簡便な構造で防水性を有し、表面がべたつかず、かつ滑らない積層シートを提供する。【解決手段】アスファルトを含む防水層の少なくとも一方の面に、メルトブローン不織布及びスパンボンド不織布を含む複数の不織布を積層した積層不織布で形成された繊維層を積層し、さらにこの繊維層の上に、（メタ）アクリル系樹脂を含む樹脂層を積層して積層シートを得る。前記積層シートは、前記樹脂層の上に、無機粒子を含む耐候層がさらに積層されていてもよい。前記繊維層の目付は３０ｇ／ｍ２以下であってもよい。前記繊維層の見掛け密度が１０〜１００ｋｇ／ｍ３であってもよい。前記繊維層は、メルトブローン不織布の両面に、スパンボンド不織布が積層した積層不織布であってもよい。前記繊維層は、複数のエンボス凹部を有する積層不織布であってもよい。前記積層シートは、屋根下葺材であってもよい。【選択図】なし
