Abstract

Perfectionnements concernant la pâte à papier, le papier et leur fabrication. On soumet à un traitement mécanique une matière première constituée essentiellement de pâte cellulosique, de préférence pâte de bois, essentiellement sans aucun traitement alcalin à froid préalable, dans une solution aqueuse fortement alcaline, c'est-à-dire une solution aqueuse contenant des cations hydroxylés à une concentration qui, dans le cas de l'hydroxyde de sodium, a une valeur comprise entre 20 et 100 g, de préférence 30 et 80 g de NaOH par litre de solution. Applicable notamment au papier à cigarettes.Improvements in pulp, paper and their manufacture. A raw material consisting essentially of cellulosic pulp, preferably wood pulp, is subjected to mechanical treatment, essentially without any prior cold alkali treatment, in a strongly alkaline aqueous solution, that is to say an aqueous solution containing cations. hydroxylated at a concentration which, in the case of sodium hydroxide, has a value between 20 and 100 g, preferably 30 and 80 g of NaOH per liter of solution. Applicable in particular to cigarette paper.
