A sheet of cellulose based material having enhanced strength, particularly the dry strength, substantially unaffected repulpability is disclosed. The sheet of cellulose based materials generally includes a first cellulose based material connected with a second cellulose base material element. The first cellulose based material is formed by separating a portion of the fiber from a furnish, treating the separated portion with a cationic wet strength resin which is allowed to bond to the fiber. The treated fiber is them mixed with the untreated balance of the fiber at some point before the paper machine. The fiber that is separated may be secondary fiber, virgin fiber or combinations thereof. The second cellulose base material element is substantially free from any treatment. The second cellulose base material element may be include substantially all untreated fibers.
