Description
Verfahren zur Herstellung von gegen Säure widerstandsfähigen Papiermacherfilzen Um P.apiermacherfilze gegen Säureeinwirkung zu schützen, ist in dem Patent .7464(18 vorgeschlagen worden, den Filz vor dem Gebrauch mit Aldehyd-Ammoniak-Verbindungen zu imprägnieren. Es ist festgestellt worden, daß sich auch andere Aldehydverbindungen als neutral wirkend zur Behandlung dieser Filze eignen. Es werden deshalb. zum Imprägnieren der Filze erfind'ungsge.mäß Aldehyd-Amin-Verbindungen, z. B. Alkylaminomethanole, die mit .der auftretenden Schwefelsäure ein neutrales Aminsulfat bilden, verwendet.Process for making acid resistant papermaker's felts In order to protect paper-making felts against the effects of acids, patent .7464 (18 It has been suggested to use the felt with aldehyde-ammonia compounds to impregnate. It has been found that other aldehyde compounds have a neutral effect for treating these felts. It will therefore. for impregnation of the felts according to the invention aldehyde-amine compounds, e.g. B. Alkylaminomethanols, which form a neutral amine sulfate with the sulfuric acid that occurs.
