Process for manufacturing an improved web material by the in-situ measurement and adjustment of ion concentration

A process for manufacturing a web material on a papermaking machine having a Yankee drum drying system, wherein said process comprises the steps of:

• a) producing said web material with said papermaking machine;
• b) measuring a molar amount of a monovalent inorganic ionizable cation species (MIICS) in said web material;
• c) measuring a molar amount of a divalent inorganic ionizable cation species (DIICS) in said web material;
• d) calculating a molar ratio of said measured molar amount of said MIICS to said measured molar amount of said DIICS in said web material;
• e) determining if said molar ratio of MIICS to DIICS is about less than or equal to 10;
• and,
• f) if said molar ratio of MIICS to DIICS is greater than about 10, applying an amount of DIICS to a surface of said Yankee drum drying system to adjust said molar ratio of MIICS to DIICS so said web material adhering to said Yankee drum drying system has a molar ratio of MIICS to DIICS of about less than or equal to 10.
