Abstract

A textile product and a method of making the same is described wherein the textile product includes a layer of metal elements, an array of stitches, and wherein the metal elements are encased between the legs of the stitch and the underlap of the stitch. Preferably, the overlaps and/or underlaps span between at least two stitch lines. This provides an improved metal element based textile product for preparing reinforced articles. The metal element based textile product of the present invention allows improved processing and improved performance as compared to conventional metal element based textile products.

First claim

The invention claimed is:

1. A textile product comprising
a layer of elongate metal elements;
an array of stitches in stitch lines, the stitches having loops with legs and underlaps and overlaps; and
wherein elongate metal elements are disposed and held between the legs of the stitch and the underlaps of the stitch and wherein the overlaps span between at least two stitch lines.

2. The textile product of claim 1 , wherein the metal elements are disposed and held between the legs of the stitch and the underlaps and overlaps of the stitch.

3. The textile product according to claim 1 , wherein the underlaps span between two or more stitch lines.

4. The textile product according to claim 1 , wherein the overlaps span between the at least two stitch lines perpendicular to the elongate metal elements.

5. An impact beam including the textile product of claim 1 , optionally made by laminating, extrusion, pultrusion, reaction injection moulding, injection, resin transfer moulding, resin infusion, compression moulding.

6. A method of making a textile product from a layer of elongate metal elements, comprising
forming an array of stitches in stitch lines and having legs and underlaps and overlaps,
wherein the elongate metal elements are held between the legs of the stitch and the underlaps of the stitch and the overlaps spanning at least two stitch lines and wherein the overlap is laid into two needles and two stitches in adjacent stitch lines are formed at the same time.

7. The method of claim 6 , including forming the array of stitches so that the metal element is held between the legs of the stitch and the underlaps and overlaps of the stitch.

8. The method according to claim 6 , wherein during stitching the underlaps are made to span between two or more stitch lines.

9. The method according to claim 6 , wherein a textile yarn spans between that at least two stitch lines perpendicular to the elongate metal elements.

10. The method according to claim 6 , wherein the stitches are obtained by a technique selected from the group consisting of mono-axial warp knitting, bi-axial warp knitting, raschel knitting, crochet knitting, and mixtures thereof.

11. The textile product of claim 1 , wherein there are more metal elements than stitch lines.

12. The method of claim 6 , including providing more metal elements than stitch lines.

13. A method of making a textile product from a layer of elongate metal elements, comprising the steps of
placing an overlap of a first stitch of a first metal element in at least a first needle and a second needle, and
forming an array of stitches in stitch lines and having legs and underlaps and overlaps, and
wherein the elongate metal elements are held between the legs of the stitch and the underlaps of the stitch and
wherein a part of the overlap joining the two stitches together forms an angle of 90° or about 90° to a stitching line.
