Abstract

Det er angitt sammensetninger og prosesser som bevarer og forbedrer lysheten og forbedrer farger til en masse eller papir ved tilsetning under fiorskjellige trinn i papirfiemstillingsprosessen. Blandingene og firemgangsmåten opprettholder og/eller fiorbedrer lyshet, fiorhindrer gulning og fiorbedrer ytelsen til papirproduktene. Brukt i kombinasjon med optiske lysningsmidler og/eller chelatdaimende midler er det beskrevet midler som danner en synergiefifekt som tidligere ikke har vært identifisert i papirfiemstillingsprosessen.Compositions and processes are provided which preserve and enhance brightness and enhance colors to a pulp or paper by addition during various stages of the paper milling process. The blends and process method maintains and / or improves brightness, prevents yellowing, and improves the performance of the paper products. Used in combination with optical brighteners and / or chelate dimming agents, agents are described which form a synergy effect that has not previously been identified in the paper milling process.
