PROBLEM TO BE SOLVED: To provide an agriculture material which maintains high thermal insulation and strength even while maintaining a wind passing effect, and which is difficult to be torn.SOLUTION: This agriculture covering material is made of an unwoven fabric provided with sheath core type composite continuous fibers. The basis weight of the unwoven fabric is 10 to 30 g/m2, the core part of the fibers is made of a polyester polymer, a sheath part is made of a polyolefin polymer, the melting point of the polymer of the sheath part is lower by 40°C or more than that of the polymer of the core part, the unwoven fabric is provided with two types of sheath core type composite continuous fibers different in fineness, namely, a thick fineness fiber having single fiber fineness set to 13 to 20 decitex and a thin fineness fiber having single fiber fineness set to 5 to 10 decitex, and the constituent fibers are integrated by a thermal compression bond part, and the area ratio of the thermal compression bond part os 10 to 30%.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】風抜け性を保持しながらも、高い保温性、強度を保持し、破れづらい農業用資材を提供することを課題とする。【解決手段】芯鞘型複合連続繊維により構成される不織布からなる農業用被覆資材であり、該不織布の目付が10~30g/m2であり該繊維の芯部がポリエステル系重合体、鞘部がポリオレフィン系重合体からなり、鞘部の重合体の融点が芯部の重合体の融点よりも40℃以上低く、不織布は、単繊維繊度が13~20デシテックスの太繊度繊維と単繊維繊度が5~10デシテックスの細繊度繊維の2種の繊度の異なる芯鞘型複合連続繊維によって構成され、構成繊維同士は、熱圧着部により一体化しており、該熱圧着部の面積率が10~30%である農業用被覆資材。【選択図】 なし
