Abstract

The invention is a method of enhancing the strength of paper products, particularly the dry strength, without adversely affecting repulpability. It is also directed to the resulting products. It is particularly applicable but not limited to products with significant amounts of secondary fiber in the furnish. Preferably, about 10-30 % of the fiber is separated from the furnish at some point prior to sheeting. This is treated with a cationic wet strength resin which is allowed to bond to the fiber. Cationic polyamide-epichlorohydrin resins are particularly useful. The treated fiber is then mixed with the untreated balance of the fiber at some point before the paper machine. Screening fines on repulping do not normally exceed 2-3 %.
