Claims: What we claim is:

1. A process for the production of metal plated staple fibers comprising providing said fibers having an areal weight of 0.5 to 5.0 kg/m.sup.2, activating said fibers and spraying an electroless metal plating solution onto the activated fibers at a space velocity of 100 to 600 m.sup.3 of said solution per m.sup.3 of said fibers per hour.

2. A process set forth in claim 1 wherein said areal weight is from 2.0 to 3.5 kg/m.sup.2.

3. A process set forth in claim 1 wherein said space velocity is from 150 to 450 m.sup.3 of said solution per m.sup.3 of said fibers per hour.

4. A process set forth in claim 1 wherein the length of said fibers is 10 to 200 mm.

5. A process set forth in claim 1 wherein said fibers are from 0.1 to 15 denier.

6. A process set forth in claim 1 wherein said fibers are synthetic.

7. A process set forth in claim 1 wherein said metal is selected from the group consisting of Ni, Cu, Co, Cr, Sn and mixtures thereof.

8. A process set forth in claim 1 wherein said solution is sprayed from a cylinder head having spray holes of 2 to 5mm in diameter and 25 to 100 holes per 100cm.sup.2 of the surface of the head.

9. A process according to claim 7 wherein the metal is Ni.

10. A process set forth in claim 6 wherein the synthetic fibers are obtained by a wet or dry spinning process.

11. A process set forth in claim 10 wherein the fiber is of polyvinyl alcohol.

12. A process set forth in claim 10 wherein the fiber is of polyacrylonitrile.
