<P>PROBLEM TO BE SOLVED: To provide a gabion using rubble of which the weather resistance is improved and in which strength reduction caused by friction is reduced. <P>SOLUTION: A gabion is configured by spreading a net within a rectangular frame line. The net is configured by weaving folded yarn as warp 1 and weft 2. The folded yarn is comprised of a plurality of pieces of polyester multifilament yarn. Furthermore, the polyester multifilament yarn is comprised of a plurality of polyester long fibers. The polyester long fiber is a core-sheath type compound long fiber of which the core component is comprised of high melting point polyester and of which the sheath component is comprised of low melting point polyester. The high melting point polyester includes carbon black. The folded yarn constituting the warp and the weft is integrated as a whole by melting and solidifying the low melting point polyester. Further, intersections of the folded yarn, namely, the intersections of the warp and the weft are also adhered by melting and solidifying the low melting point polyester. <P>COPYRIGHT: (C)2013,JPO&INPIT |
