Abstract

A fabric (144) for use as a stab-resistant insert in protective textiles comprises a plurality of steel cords (100). Each of the steel cords (100) comprises a longitudinal axis (102) and two or more steel filaments (104). Each of the steel filaments (104) forme a twisting angle α with the longitudinal axis (102) of the steel cord (100). The steel cords (100) have two or more of such twisting angles which are substantially different from each other so that any penetrating stab or knife is stopped.

Claims

1. A fabric for use as a stab-resistant insert in protective textiles, said fabric comprising a plurality of steel cords, each of said steel cords comprising a longitudinal axis and two or more steel filaments, each of said steel filaments having a diameter greater than 0.05 mm, each of said steel filaments forming a twisting angle with the longitudinal axis of said steel cord, said steel cords having two or more of such twisting angles which are substantially different from each other.

2. A fabric according to claim 1, wherein said steel cords have three or more of such twisting angles which are substantially different from each other.

3. A fabric according to claim 1 wherein said filaments which form said substantially different twisting angles appear at least partially at the surface of the steel cord.

4. A fabric according to claim 1 wherein said fabric is a woven structure.

5. A fabric according to claim 4 wherein said woven structure has said steel cords as warp.

6. A fabric according to claim 4 wherein said woven structure has said steel cords as weft.

7. A fabric according to claim 4 wherein said woven structure has said steel cords as warp and weft.

8. A fabric according to claim 1 wherein said fabric is a knitted structure.

9. A fabric according to claim 1 wherein said fabric is a knotted structure.

10. A fabric according to claim 1 wherein said fabric has been coated with an adhesive.

11. A fabric for use as a stab-resistant insert in protective textiles, said fabric comprising a woven structure having non-metallic filaments forming a binding between warp and weft and comprising a plurality of steel cords, each of said steel cords comprising a longitudinal axis and two or more steel filaments, each of said steel filaments forming a twisting angle with the longitudinal axis of said steel cord, said steel cords having two or more of such twisting angles which are substantially different from each other.
