<P>PROBLEM TO BE SOLVED: To provide a net for use in a roll window screen, which achieves enhanced viewability with a suitable taking-up property; a roll window screen having the net; and a fitting. <P>SOLUTION: A warp 21 and a weft 22 of a net body 20 have a core part 25 and a sheath part 26 by multilayer molding, each of which is formed of resin having a different melting point, capable of having a relatively thin thread diameter. Consequently, the viewability through the net body 20 can be enhanced. In addition, the cross section ratio of the core part 25 to the sheath part 26 (core/sheath ratio) is set in a predetermined range, such that the warp 21 and the weft 22 have a proper flexural hardness. Consequently, the net body 20 can have a suitable taking-up property without enlarging a taking-up diameter, preventing occurrence of wrinkles. <P>COPYRIGHT: (C)2012,JPO&INPIT |
