Description
Verfahren zum Bleichen von rohen, maschinell gewonnenen grünen Pflanzenfasern aller Art Die Erfahrung hat gezeigt, daß die Struktur der grünen Naturfasern beim Bleichen mit staxl,-er Hypochoritlauge beeinträchtigt -wird. I[Zür die Behandlung dieser Fasern mußte deshalb nach einem geeigneten Verfahren g gesucht werden, uni sie gut C zu bleichen, ohne die Struktur zu verändern. Es -wurden Versuche mit trockenem Chlorgas angestellt. Dabei wurden ausgezelchnete Erfolge erzielt. Die Behandlung nach dieser Methode geht folgendermaßen vor sich: Die mit den verschiedenen im Gebrauch befIndlichen Entfleischungsmaschinen gewonnenen grünen Rohfasern werden vier Prozessen unterworfen - i. Zunächst -wird die Rohgrünfaser in einer Kammer mit Chlorgas unter Druck gebleicht (s. die Abbildung).Process for bleaching raw, machine-made green vegetable fibers of all kinds Experience has shown that the structure of the green natural fibers is impaired when bleached with staxl, hypochlorite liquor. For the treatment of these fibers it was therefore necessary to look for a suitable method to bleach them well without changing the structure. Experiments were made with dry chlorine gas. Thereby exceptional successes were achieved. The treatment according to this method proceeds as follows: The green raw fibers obtained with the various deflashing machines in use are subjected to four processes - i. First, the raw green fiber is bleached in a chamber with chlorine gas under pressure (see illustration).
2. Die so gebleichten Fasern werden hierauf bei 'etwa 30' Mit Chlorlauge behandelt, die unter Iffitverwendung der von der Chlorgasbleichung stammenden chlorhaltigian Abgase hergestellt worden ist, und die geg gebenenfalls Glycerin enthält.2. The fibers bleached in this way are then treated at 'about 30' with chlorine liquor, which has been produced using the chlorine-containing exhaust gases from the chlorine gas bleaching and which may contain glycerine.
3. Die so gebleichten und nachbehandelten Fasern werden in einer Schleuder mit kaltem Wasser gut durchgespült und anschließend geschleudert. 3. The fibers bleached and treated in this way are rinsed thoroughly with cold water in a centrifuge and then centrifuged.
4. Die aus der Schleuder nahezu trocken kommenden Fasern werden in Trockenkammern oder an der Luft bis zu dem gewünschten Feuchtigkeitsgrad getrocknet.4. The fibers coming out of the centrifuge are almost dry Kiln or air dried to the desired level of humidity.
Man erzielt bei dieser Arbeitsweise eine Veredlung, der Faser ohne Schädigung der Faserstruktur.In this way of working, the fiber is refined without Damage to the fiber structure.
Die Zeichnung dient zur Veranschaulichung der Bleichkauuner. Die Kammer besteht aus einem zylindrischen Behälter, dessen vordere Seite durch eine Tür verschlossen wird. Klinkeriteinlagen und Tresormutterverschraubung ermöglichen einen unbedingt dichten Verschluß. Nachdem die Siebe S mit grünen Fasern beschickt worden sind" wird die Tür T fest verschlossen und aus der Flasche F Chlorgas eingeleitet. Die zunächst in der Kammer befindliche Luft wird von dem Chlorgas verdrängt und entweicht durch das Ventil V. Durch das Manometer ill und durch das Regulierventil R wird der Druck in der Kammer geregelt. Nach kurzer Zeit ist die Bleichung beendet. Das Chlorgas wird durch eine Pumpe in einen nicht gezeichneten Laugenbehälter B gedrückt. Nachdem das Gas aus der Kammer restlos abgesaugt worden ist, wird die Tür T geöffnet. Die Fasern werden auf den Sichen in das vorbereitete Bad gesenkt und dort kurze Züit der Einwirkung ausgesetzt. Darnach erfolgt die Durchspülung und das Schleudern.The drawing serves to illustrate the Bleichkauuner. The chamber consists of a cylindrical container, the front side of which is closed by a door. Clinkerite inlays and safe nut screw connections enable an absolutely tight seal. After the sieves S have been filled with green fibers, the door T is tightly closed and chlorine gas is introduced from the bottle F. The air initially in the chamber is displaced by the chlorine gas and escapes through the valve V. Through the manometer III and through the pressure in the chamber is regulated by regulating valve R. After a short time the bleaching is finished. The chlorine gas is pressed by a pump into a tub B (not shown). After the gas has been completely sucked out of the chamber, the door T is opened. The fibers are lowered onto the prepared bath where they are briefly exposed to the action, followed by rinsing and spinning.
