REFLECTION SHEET INCLUDING SURFACE PROJECTION AND MANUFACTURING METHOD THEREOF, AND MONOFILAMENT FOR INSECT PROOF NET INCLUDING SURFACE PROJECTION AND INSECT PROOF NET

摘要

PROBLEM TO BE SOLVED: To provide material that has an increased diffuse reflection factor, is good in strength, can retain durability in a harsh application, and can be simply manufactured, and also to provide an insect proof net and its material that block the intrusion of a noxious insect flying and coming from the outside.;SOLUTION: A stretched reflection tape 1 is made by stretching olefin resin film including a large number of fillers 12 that reflect light from a light source toward periphery. The fillers are larger in specific gravity than olefin resin 11 and high in rigidity. On the basis of stretching, voids 13 are formed around the fillers, and due to thinning of the film, a large number of surface projections 14 having the fillers and the voids as cores are formed on the surface of the tape. A monofilament for an olefin resin insect proof net whose cross section shape is nearly circular or nearly polygonal has a large number of projections formed on its surface.;SELECTED DRAWING: Figure 1A;COPYRIGHT: (C)2017,JPO&INPIT
