Zusammenfassung:The present invention is generally directed to a process for recycling paper broke containing a wet strength additive. More particularly, the present invention is directed to a process for recycling paper broke containing a wet strength additive by mechanically fiberizing the broke into substantially discrete fibers. Once recycled into discreet fibers, the broke can then be used in forming any paper product, such as wipers and tissues. The present invention is generally directed to a process for recycling paper containing wet strength additives. The process generally includes the step of mechanically fiberizing the paper in order to reduce the paper into substantially discreet fibers. The paper can be fiberized in various devices, including mills and pulverizers. Once the paper has been converted into substantially discreet fibers, the fibers can then be used in forming various paper products, including wipers and tissues. Of particular advantage, it has been discovered that fibers produced according to the process of the present invention produce paper webs having high bulk, high brightness, high porosity, and high opacity.
