METHOD OF INHIBITING WET STRENGTH RESIN DEPOSITION IN PAPERMAKING FELTS |
摘要 |
This invention relates to an improved press felt conditioning treatment which controls the deposition of poly(aminoamide) - epichlorohydrin type resins in a press felt. The treatment comprises applying to the felt an effective inhibiting amount of a conditioner comprising: an ethoxylated nonylphenol having greater than about 30 moles of ethoxylation; sodium n-hexadecyl diphenyloxide disulfonate; a fatty acid imidazoline or an alkylamidopropyldimethylamine which include an alkyl hydrophobe substituent having a carbon chain length of about 18.
