Abstract

A process having the steps of producing the web material with the papermaking machine; measuring a molar amount of a monovalent inorganic ionizable cation species (MIICS) in the web material; measuring a molar amount of a divalent inorganic ionizable cation species (DIICS) in the web material; calculating a molar ratio of the measured molar amount of the MIICS to the measured molar amount of the DIICS in the web material; determining if the molar ratio of MIICS to DIICS is about less than or equal to 10; and, if the molar ratio of MIICS to DIICS is greater than about 10, adding an amount of DIICS to the papermaking machine to adjust the molar ratio of MIICS to DIICS so the web material adhering to the Yankee drum drying system has a molar ratio of MIICS to DIICS of about less than or equal to 10, is disclosed.
