Abstract

The invention relates to a method and an apparatus for the production of décor paper ( 7 ) having an abrasion-resistant surface. The production method includes applying a coating of abrasion resistant particles and resin to the décor paper, followed by applying electrically charged fibers onto the coating. The invention further relates to paper made according to said method.

Claims (11)

1. Method for the production of a décor paper having an abrasion resistant coating ( 1 , 11 ) and fibers, which are mounted onto or at the abrasion resistant coating ( 1 , 11 ) comprising the steps of:

providing a décor paper;

applying a coating comprising abrasion resistant particles ( 1 ) comprising aluminum oxide together with resin onto the décor paper; and afterwards

applying electrically charged fibers ( 10 ) onto the coating consisting of abrasion resistant particles and the resin, wherein at least a majority of the fibers are in an upright position with respect to the décor paper.

2. Method according to claim 1 , wherein the décor paper provided with the fibers ( 10 ) is subsequently dried.

3. Method according to claim 1 , wherein a mixture of resin and abrasion resistant particles is sprayed onto the décor paper and excess resin is recirculated from the paper to the mixture, wherein after the spraying and before the application of fibers, the paper with the applied layer is preferably dried.

4. Method for the production of a décor paper having an abrasion resistant coating ( 1 , 11 ) and fibers, which are mounted onto or at the abrasion resistant coating ( 1 , 11 ), comprising the steps of:

providing a décor paper;

impregnating the décor paper with resin;

providing abrasion resistant particles ( 1 ) comprising aluminum oxide with an adhesion promoter;

spreading the abrasion resistant particles onto the paper; and afterwards applying electrically charged fibers ( 10 ) onto the coating consisting of abrasion resistant particles and resin, wherein at least a majority of the fibers are in an upright position with respect to the décor paper.
