Abstract
A process for manufacturing a web material is disclosed. The process generally comprises the steps of providing a papermaking machine with a monovalent inorganic ionizable cation species (MIICS) and a divalent inorganic ionizable cation species (DIICS) measuring devices, measuring molar concentrations of MIICS and DIICS in the web material with the MIICS and DIICS measuring devices and calculating a molar ratio of the measured molar concentration of the MIICS to the measured molar concentration of the DIICS, and subsequently determining if the calculated molar ratio is about less than or equal to 10. If the molar ratio is greater than 10, adding an amount of DIICS to the papermaking machine and manufacturing the web material with the papermaking machine with the added amount of DIICS.
