Description

Dotychczas nie mozna bylo stosowac z powodzeniem blonnika siarczynowego do wyrobu bibulki papierosowej z tego powodu, ze papier, wytworzony z tego materjalu, posiada nieprzyjemny smak, który nie móglby byc usuniety nawet przez gruntowne przemywanie surowca, uzy¬ tego do wyrobu papieru i t. d.Niniejszy wynalazek stwierdza nato¬ miast, ze udaje sie z latwoscia wyrabiac papier, pozbawiony wszelkiego nieprzy¬ jemnego smaku, nawet z blonnika siar¬ czynowego, jezeli sie podda ten ostatni traktowaniu alkalicznemu. Substancje, wywolujace smak nieprzyjemny, sa prawdopodobnie natury kwasnej i ule¬ gaja wskutek tego usunieciu zapomoca plynów alkalicznych. Nadaja sie do te¬ go celu najrozmaitsze alkalja, jako to: lug sodowy lub potasowy, woda wa¬ pienna, amonjak, roztwór sody j. t. p.Postepuje sie przytem w ten prosty sposób, ze blonnik siarczynowy przed bieleniem, lub tez po niem poddaje sie dodatkowemu traktowaniu w kapieli al¬ kalicznej, np. w 2 - procentowym lugu sodowym, poczem alkalja wymywa sie i przerabia materjal dalej w zwykly spo¬ sób na bibulke papierosowa. W zalez¬ nosci od wiecej lub mniej silnego wy¬ stepowania nieprzyjemnego smaku w pa¬ pierze stosuje sie wiecej lub mniej in¬ tensywne traktowanie pod wzgledem czasu trwania, koncentracji lugu alka¬ licznego, temperatury i t. d. W razie potrzeby stosuje sie podgrzewanie lub tez nawet równoczesnie i sztuczne cisnienie* PL PLUntil now, it has not been possible to successfully use sulfite fiber in the manufacture of cigarette paper because paper made from this material has an unpleasant taste that cannot be removed even by thorough washing of the raw material used for making the paper, etc. The present invention, however, has shown that it is possible to easily produce paper free from any unpleasant taste, even from sulfite fiber, if the latter is subjected to an alkaline treatment. The substances causing the unpleasant taste are probably acidic in nature and are therefore removed by alkaline liquids. Various alkalis are suitable for this purpose, such as sodium or potassium hydroxide solution, limewater, ammonia, soda ash solution, etc. The simple procedure is to treat the sulfite fiber in an alkaline bath, e.g., 2% sodium hydroxide solution, before or after bleaching. The alkali is then washed out and the material is further processed in the usual way into cigarette paper. Depending on the more or less intense presence of unpleasant taste in the paper, more or less intensive treatment is applied in terms of duration, alkali hydroxide concentration, temperature, etc. If necessary, heating or even simultaneous application of artificial pressure is used.
