METHOD OF MAKING PAPER WITH HIGH FILLER CONTENT

METHOD OF MAKING PAPER WITH HIGH FILLER CONTENT

The invention relates to a method for producing paper by the addition of a retention - dry strength agent system. The system consists of cationic starch with a substitution degree of at least 0.005 in an amount of at least 1%, anionic high-polymer with a molecular weight greater than 106 and in an a...

Zusammenfassung:The invention relates to a method for producing paper by the addition of a retention - dry strength agent system. The system consists of cationic starch with a substitution degree of at least 0.005 in an amount of at least 1%, anionic high-polymer with a molecular weight greater than 106 and in an amount of 0.003-0.5%, and cationic synthethic polymer in an amount of 0.005-0.5%.
