PROBLEM TO BE SOLVED: To provide an industrial material sheet such as a tarpaulin, a canvas and a mesh sheet, which can maintain control effect (repellent effect) on harmful flying insects for a long time used for a tent, a sun shade, a construction cured sheet, a lighting signboard, a partition, a ceiling film and the like.SOLUTION: An industrial material sheet is a flexible sheet which comprises: a fiber fabric which is a base cloth and a thermoplastic resin layer which covers the front and rear surfaces of the fiber fabric. The thermoplastic resin layer includes cyclodextrin-silica composite particles supporting pyrethroid-based compounds in specific amounts. A part of the cyclodextrin-silica composite particles is exposed on the surface of the thermoplastic resin layer.COPYRIGHT: (C)2015,JPO&INPIT【課題】飛翔性害虫の防除効果(忌避)が長期間安定持続するターポリン、帆布、メッシュシートなどの産業資材シート(テント、日除け、建築養生シート、電照式看板、間仕切り、天井膜など)の提供。【解決手段】繊維織物を基布として含み、その表裏を被覆する熱可塑性樹脂層とで構成された可撓性シートにおいて、熱可塑性樹脂層に、ピレスロイド系化合物を担持するシクロデキストリン-シリカ複合粒子を、熱可塑性樹脂層に対して特定量含み、この複合粒子の一部が熱可塑性樹脂層表面に露出するようにする。【選択図】図1
