Fabric web for erosion protection

Claim 2

A fabric web for the erosion protection of earth layers, the fabric web comprising: a plurality of threads crossing one another at substantially right angles forming a fabric web plane, said plurality of threads including warp threads and weft threads, said warp threads crossing said weft threads; and individual loop threads projecting from said fabric web plane at irregular intervals with respect to the fabric web plane in the form of loops or said individual loop threads are tufted and in each case cover at least one crossing thread; wherein said warp, weft, and loop threads are made exclusively from vegetable fibers.

Claim 3

A fabric web according to claim 1, wherein said individual loop threads are arranged substantially parallel to said warp threads, substantially parallel to said weft threads, irregularly arranged within said web, or combinations thereof.

Claim 4

The fabric web according to claim 1, wherein each said individual loop thread jumps over at least one of said warp threads.

Claim 5

The fabric web according to claim 1, wherein each of said threads jumps over at least one said weft thread.

Claim 6

The fabric web according to claim 1, having a distance defined between adjacent warp or weft threads, wherein said distance is substantially regular throughout said fabric web.

Claim 7

The fabric web according to claim 5, having a distance defined between a loop thread and an adjacent warp or weft thread, wherein said distance between a loop thread and an adjacent warp or weft thread is less than the distance between adjacent warp or weft threads.

Claim 8

The fabric web according to claim 6, having a distance defined between a warp or weft thread adjacent to a loop thread and a next-adjacent warp or weft thread, wherein said distance between a warp thread adjacent to a loop thread and a next-adjacent warp or weft thread is greater than the distance between warp or weft threads not adjacent to a loop thread.

Claim 9

The fabric web according to claim 1, wherein the loops of said loop threads project out of said fabric web plane by at least 1.0 cm.

Claim 10

The fabric web according to claim 7, wherein the loops of said loop threads project out of said fabric web plane by at least 1.0 cm.

Claim 11

A fabric web for the erosion protection of earth layers, the fabric web comprising: a plurality of threads crossing one another at substantially right angles to form a generally planar web; a plurality of loop threads passing through said generally planar web and crossing above and below said planar web or irregular intervals; wherein said loop threads project from the plane of said web in the form of loops, and wherein the fabric and threads are made exclusively from vegetable fibers.

Claim 12

A fabric web for the erosion protection of earth layers, the fabric web comprising: a plurality of threads crossing one another at substantially right angles to form a generally planar web; a plurality of loop threads passing through said generally planar web and crossing above and below said planar web or irregular intervals; wherein said loop threads project from the plane of said web in the form of loops, and wherein the fabric and threads are made exclusively from vegetable fibers.

Claim 13

The fabric web of claim 10, wherein each of said loop threads loop crosses at least one said thread forming said generally planar web.

Claim 14

The fabric web of claim 11, wherein said loops project out of said fabric web plane by at least 1 cm.

Claim 15

The fabric web of claim 12, wherein all said threads and said loop threads are made out of vegetable fibers.

Claim 16

A fabric web for the erosion protection of earth layers, the fabric web comprising: a plurality of weft threads in a substantially parallel, planar arrangement; a plurality of warp threads in a substantially parallel arrangement; wherein said warp threads are substantially perpendicular to said weft threads and said warp threads alternatively cross said weft threads above and below said weft thread plane to form a generally planar web; and a plurality of loop threads passing through said generally planar web and crossing above and below said generally planar web; wherein said loop threads project from the plane of said web in the form of loops, and wherein the fabric and threads are made exclusively from vegetable fibers.

Claim 17

A fabric web for the erosion protection of earth layers, the fabric web comprising: a plurality of weft threads in a substantially parallel, planar arrangement; a plurality of warp threads in a substantially parallel arrangement; wherein said warp threads are substantially perpendicular to said weft threads and said warp threads alternatively cross said weft threads above and below said weft thread plane to form a generally planar web; and a plurality of loop threads passing through said generally planar web and crossing above and below said generally planar web; wherein said loop threads project from the plane of said web in the form of loops, and wherein the fabric and threads are made exclusively from vegetable fibers.

Claim 18

The fabric web of claim 14, wherein the loops of said loop threads project out of said fabric web plane by at least 0.5 cm.

Claim 19

The fabric web of claim 15, wherein said loops project out of said fabric web plane by a least 1 cm.

Claim 20

The fabric web of claim 14, wherein each of said loop threads crosses at least one said warp thread or one said weft thread.

Claim 21

The fabric web of claim 15, wherein said loops project from said generally planar web in irregular intervals.
