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 supporting pyrethroid-based compounds in specific amounts. A falling-off resin layer is partly formed on the surface of the thermoplastic resin layer. An occupied area ratio of the falling-off resin layer is 10-50% of the surface area of the thermoplastic resin layer.COPYRIGHT: (C)2015,JPO&INPIT【課題】飛翔性害虫の防除効果(忌避)効果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を、熱可塑性樹脂層に対して特定量含み、この熱可塑性樹脂層の表面に脱落性樹脂層を部分的に形成し、この脱落性樹脂層の占有面積率を熱可塑性樹脂層の表面積に対して10~50%とする。【選択図】図1
