Improved machine speeds in the production of paper have increased the number of wet-end breaks due to wet-webs that are unable to withstand the increased stresses at increased rates of production. Lyne and Gallay layed the cornerstone on which most of today"s knowledge of wet-web strength is built. This research attempted to expand on this knowledge by determining whether chemicals could be employed to improve wet-web strength.

The results of this experiment indicates that cationic polymers do improve wet-web strength at levels of addition of 160 lbs/ton of pulp and 1600 lbs/ton of pulp. This indicates that cationic polymers are a potential means of improving wet-web strength.
