Description
, Niniejszy wynalazek ma za zadanie w trudno macerujacych sie roslinach wlóknistych, ewentualnie wlóknach roslin¬ nych, jak np., w slomie lnu lub konopi, w pakulach, lodygach roslin tytuniowych, jucie, lodygach bananowych i t. p. zdre¬ wniale w znacznym stopniu kompleksy wlókien rozszczepiac tanim i prostym sposobem, i wlókna rozszczepione oddzie¬ lic. W tym celu posilkowac sie nalezy wspóldzialaniem dwóch sposobów, zna¬ nych juz kazdy oddzielnie, mianowicie go¬ towaniem w lugach siarczynowych i dzia¬ laniem roztworów alkalicznych.W glównych swych zarysach niniejszy nowy sposób przedstawia sie jak naste¬ puje: .Rosliny wlókniste, wzgl. wlókna roslin¬ ne po uskutecznieniu zwyklego oczyszcze¬ nia i pokrajaniu na kawalki o dlugosci, od¬ powiadajacej dlugosci wlókien, gotuje sie pod cisnieniem w lugach siarczynowych (przy temperaturze nieprzekraczajacej 125° do 130°C i pod cisnieniem nie wyz- szem nad 5 do 6 atmosfer). W przeciwsta¬ wieniu do zwykle stosowanych lugów siar¬ czynowych, uzywa sie tu lugów o charak¬ terze silnie zasadowym, zawierajacym 60 do 100 czesci wagowych CaO na 100 czesci SO2. Po ukonczeniu gotowania, trwajacego stosownie do okolicznosci od 6 do 12 godzin, przenosi sie mase do ka¬ pieli alkalicznej (roztworu 5 do 10% sody amonjakalnej, lub kaustycznej) i tam pod¬ daje ja obróbce mechanicznej w celu wy-, macerowania rozmieklych, substancyj drzewnych i oddzielenia od nich nieuszko¬ dzonych wlókien. Operacje powyzsza wy-konywa sie w holendrze, lub w jakiejkol¬ wiek podobnie funkcjonujacej maszynie do skrobania.Oddzielone w ten sposób wlókno plócze sie, bieli, jesli zachodzi tego potrzeba, i sto¬ suje jako zupelnie przydatny materjal do celów przedzalniczych, o ile nie podlega ono przeróbce na blonnik.Pozostale lugi moga byc uzyte w znany jakikolwiek sposób, co jednak nie wcho¬ dzi w zakres niniejszego wynalazku. PLThe object of the present invention is that in difficult to macerate fiber plants, or plant fibers, such as, for example, in flax or hemp straw, in tow, stalks of title plants, jute, banana stalks, etc. split in a cheap and simple manner, and the split fibers must be separated. For this purpose, it is necessary to use two methods, already known each separately, namely boiling in sulphite liquors and the action of alkaline solutions. the method is as follows:. Fibrous plants or After the usual cleaning and cutting into pieces of a length corresponding to the length of the fibers, plant fibers are boiled under pressure in sulphite pools (at a temperature not exceeding 125 ° to 130 ° C and at a pressure not exceeding 5 to 6 atmospheres). In contrast to the usual sulfite lyes, strongly alkaline lyes are used, containing 60 to 100 parts by weight of CaO per 100 parts of SO2. After cooking, which lasts from 6 to 12 hours, is completed, the mass is transferred to an alkaline bath (a 5 to 10% solution of ammonia or caustic soda) and mechanically processed there to macerate wood substances and separating the undamaged fibers therefrom. The above operations are carried out in a Dutch or some similarly functioning scraping machine. The separated fiber tears, white if necessary, and is used as a perfectly suitable material for pre-cutting purposes, unless it is processed into fiber. The other lugs may be used in any manner known per se, but do not fall within the scope of the present invention. PL
