a backing layer and

a polishing layer made of sheep wool fibres fixed on a surface of the backing layer,

wherein the polishing layer comprises loops made of sheep wool fibres,

wherein the sheep wool fibre loops are knitted, weft-knitted or woven into the backing layer, and

wherein the polishing layer comprises surface weight of at least 500 g/m 2 .

2. Material for a polishing pad according to the claim 1 , wherein the sheep wool fibre loops comprise arc height of 5-25 mm from the backing layer.

3. Material for a polishing pad according to claim 1 , wherein the polishing layer comprises surface weight of 500-1500 g/m 2 .

4. Material for a polishing pad according to claim 1 wherein the backing layer comprises knitted or woven fabric.

5. Material for a polishing pad according to claim 1 , wherein the backing layer is made of yarn and sheep wool fibres.

6. Material for a polishing pad according to claim 1 , wherein the sheep wool fibres comprise sheep wool from at least two separate sources.

7. Material for a polishing pad according to claim 1 , wherein the loops comprise legs attached into backing layer and arc portions connecting two legs, wherein the arc portion connecting two legs is arranged to provide a structure perpendicular with the legs.

8. Material for a polishing pad according to claim 1 , wherein the backing layer is impregnated in order to lock the sheep wool fibre loops into the backing layer.

9. A polishing pad comprising

a backing layer and

a polishing layer made of sheep wool fibres fixed onto a surface of the backing layer,

wherein the polishing layer comprises loops oriented to contact a surface for polishing, the loops made of sheep wool fibres,

wherein the sheep wool fibre loops are knitted, weft-knitted or woven into the backing layer, and

wherein the polishing layer comprises surface weight of at least 500 g/m 2 .
