Disclosed herein are treated pulp sheets comprising cellulose pulp fibers treated with a densifying agent and having a relatively low moisture content. In certain embodiments, the treated pulp sheets are used to produce fiberized pulp having an unexpectedly low knot content, while maintaining density and softness properties usually associated with similarly treated pulp that is fiberized at higher moisture content. Methods of making fiberized pulp from the treated pulp sheets, as well as products comprising the treated pulp sheets or fiberized pulp from the treated pulp sheets, are also provided.

A method for producing a modified lignocellulosic pulp having improved wet-strength properties and a modified lignocellulosic pulp obtainable by the method.

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.
