Embodiment Construction

[0034] figure 1 A schematic top view of a lattice-shaped warp-knitted fabric. The lattice 1 is formed from groups of 2 warp threads which lie against weft threads 3 likewise arranged in groups.

[0035] The loops of fixed yarn 4 extend along warp yarn 2, at figure 1 The fixed yarns are shown with large zigzag lines and small circles in .

[0036] The mesh size in the intersection area 5 of the warp yarn 2 and the weft yarn 3 is smaller than the mesh size in the area of ​​the lattice hole 6 . The idea of ​​the design of the present invention is that the required mesh size in the intersecting range 5 constituting the connection point is smaller than the mesh size in the lattice opening 6, so that each warp yarn and the ground warp are fixed to each other.

[0037] The size of the loops of the fixed yarn 4 simultaneously constitutes the dimension of the entire geometric lattice 1 design. The meshes of the geometrical lattice are called macropores, since the mutual spacing bet...

Abstract

A method for making wide-mesh warp knit fabric involves forming tricot-laid loops of fixing threads (4) along the warp threads (2) at both the coss-overs and the mesh openings without twisting (2), running (2) through the knitting tools with no misalignment, binding warp and weft threads together with (4) at the cross-overs and periodically changing the pull-off speed to make it lower when the cross-overs pass through the knitting station and higher when the mesh openings pass through. A method for the production of warp knit fabric with a biaxial wide-mesh structure, in which (a) a crosswise arrangement of warp (2) and weft (3) threads (singly or in groups) is taken to a knitting station (8), (b) loops (20) of fixing threads (4) are formed along the warp threads both at the cross-over points (5) and also at the mesh openings (6), (c) the loops (20) are tricot-laid, (d) the warp threads run through the knitting tools with no misalignment, (e) the loops (20) are formed without twisting the warp threads, (f) the warp and weft threads (2, 3) are bound together by the fixing threads (4) at the cross-overs (5), (g) the mesh structure is pulled off the station (8) and (h) the pull-off speed is periodically changed, being lower when the cross-overs (5) are passing through the knitting station (8) and higher when the mesh openings (6) are passing through.

Description

technical field [0001] The present invention relates to a method for producing warp knitted fabrics with a biaxial mesh structure with large lattice openings, said method being particularly suitable for producing so-called geometric lattice fabrics (also known as Geo-Grid-Ware ), as disclosed, for example, in DE19957019A1. This geometric lattice fabric has an intersecting arrangement of warp and weft yarns which are connected at their intersections by loops of fixed yarns. Background technique [0002] Geometric lattice fabrics are used in natural landscape protection projects, road construction projects and high-rise building projects. Where large quantities of large-area geometric lattice fabrics are consumed, the fabrics must therefore be mass-produced and strong and inexpensive. A further design of the geometric lattice fabric for various uses is made in DE19957019A1, wherein the geometric lattice fabric has a plastic coating and is connected with a non-woven fabric or...
