A method of manufacturing sanitary paper for handling dog feces is disclosed. The sanitary paper has good water resistance, wet strength, elasticity, and water dispersibility. As a result, the sanitary paper can be used to collect and carry feces and can be disposed of in a toilet. Since the sanitary paper manufactured has water resistance, appropriate wet strength, flexibility, and water dispersibility, the sanitary paper can easily be used to wrap and sanitarily carry dog feces and will not clog of a toilet when the sanitary paper is flushed down a toilet.

A method to produce dried single-layer or multi-layer paper is disclosed. The method comprises, for a single-layer paper, preparing and spraying a partially dehydrated first fibrous web with a spray solution or suspension to give a sprayed partially dehydrated first fibrous web, and dehydrating the sprayed partially dehydrated first fibrous web by applying heat to form a dried single-layer paper; or, for a multi-layer paper, preparing and spraying a partially dehydrated layer compound with a spray solution or suspension to form a sprayed layer compound, and dehydrating the sprayed layer compound by applying heat to form a dried multi-layer paper. The spray solution or suspension comprises water and at least one water-soluble polymer P, which is obtained by polymerizing: (i) a monomer of formula H.sub.2CCHNHC(0)R.sup.1, where R.sup.1 is H or C.sub.1-C.sub.6- alkyl; and (ii) one or more ethylenically unsaturated monomers different from monomer (i).

The present invention provides a process for producing paper or board, comprising slushing a stock of dried fibres in a slushing system comprising a pulper, and/or feeding a stock of never-dried fibres in a fiber line of an integrated paper mill; deflaking and/or refining the stock in a deflaker and/or a refiner, optionally diluting the deflaked and/or refined stock, directing the deflaked and/or refined stock to a headbox, forming a web, and drying the web, wherein a polymeric paper making additive is added to one or more of the stocks of dried fibres and never-dried fibres before deflaking and/or refining of the stock. The present invention further provides paper and board with improved properties.
