Invention-wise three-dimensional net made by warpnknitting has high shape retainability in three-dimensionalncords defining three-dimensional mesh spaces, capability ofnsuppressing direction dependency, superiority in structuralnstability and pressure resistance, capability of retainingna suitable degree of elasticity and formation ofnthree-dimensional cords simply by imparting tension, highnvoid content, and lightweight, which are suitable for variousnapplications. Invention-wise three-dimensional net formednby warp knitting comprises a first mesh web, a second meshnweb and connecting yarns 3 connecting the first and secondnmesh webs 1 and 2, on front and back sides of the net, withna required spacing therebetween; further comprisesnthree-dimensional cords each formed by braids on the firstnmesh web and the second mesh web 1 and 2 and by the connectingnyarns 3 front-to-back-wise passed between the braids 11 andn12 of the first and second mesh webs 1 and 2, said first meshnweb 1 having larger mesh openings than those of the secondnmesh web 2. At least partly in each of said three-dimensionalncords 4, said connecting yarns 3 are passed from a single braidn11 on the first mesh web 1 to a plurality of braids 21 on thensecond mesh web 2 so that said three-dimensional cord 4 hasna width of at least one mesh openings 12 on the first meshnweb 1. |
