Title (EN) PROCESS FOR PRODUCING THIN PAPER
(FR) PROCÉDÉ DE PRODUCTION DE PAPIER FIN
(JA) 薄葉紙の製造方法
Abstract:
(EN) A process for producing thin paper, the process comprising a stock preparation step in which a stock, which is a suspension of fibers, is prepared from raw materials and a papermaking step in which a fibrous web is formed from the stock by a wet-lay method and is then dried while being conveyed. The stock preparation step includes the step of adding a dilute softener liquid to the stock. In the dilute softener liquid, the softener is dispersed in the form of fine droplets having an average diameter of 2.7 μm or smaller.
(FR) L'invention concerne un procédé de production de papier fin, le procédé comprenant une étape de préparation de pâte dans laquelle une pâte, qui est une suspension de fibres, est préparée à partir de matières premières et une étape de fabrication de papier dans laquelle une bande fibreuse est formée à partir de la pâte par un procédé de pose par voie humide et est ensuite séchée tout en étant transportée. L'étape de préparation de pâte comprend l'étape consistant à ajouter un liquide adoucissant dilué à la pâte. Dans le liquide adoucissant dilué, l'adoucissant est dispersé sous la forme de fines gouttelettes présentant un diamètre moyen égal ou inférieur à 2,7 µm.
(JA) 原料から繊維の懸濁液である紙料を調整する紙料調整工程と、前記紙料から繊維を抄いて繊維ウェブとしたものを搬送しながら乾燥する抄紙工程とを含む薄葉紙の製造方法であって、前記紙料調整工程は、柔軟剤の希釈液を前記紙料に添加する工程を含み、前記柔軟剤の希釈液中には、前記柔軟剤が、平均粒径が2.7μm以下の微粒子の形態で分散している。
