FIELD: textiles, paper.
SUBSTANCE: wear proof particles are treated with adhesion promoter based on silane or sylon and then deposited on paper, impregnated with resin, thereby obtaining coating. Fibre is electrically charged and put onto the coating. Drying is then carried out. The device for implementing the given method has a equipment for depositing wear proof particles on paper, equipment for charging fibre and putting the charged fibre onto the paper. The latter consists of a roller with depressions, made with provision for rotating, and a brush mounted near the roller for cleaning the depressions. The device also has apparatus for electrically charging the roller and/or the brush and the roller, which is made with provision for rotation and passing paper sheets under the roller with depressions. Paper, made using this technique, has a wear proof coating and electrically charged fibres on the wear proof coating. The charged fibres used can be made from polyester and/or cotton, and/or cotton linter.
EFFECT: obtaining wear proof paper with improved properties.
