Description
Nach dem Patent 902 427 wird ein trockenes Krempelvlies, das ganz oder vorwiegend aus Kunstfasern auf Cellulosebasis, ζ. Β. aus Viskosefasern besteht, auf einem Laufband durch ein kurzdauerndes verdünntes Laugebad geführt. In gleicher Weise kann man auch ein feuchtes Faservlies über ein System von Absaugtrommeln führen. Durch verschiedene Vorgänge, die unter der Bezeichnung Verschmelzung der Fasern zusammengefaßt wurden, bildet sich dabei ein fest zusammenhaltendes stoffartiges Gebilde.According to the patent 902 427, a dry carded fleece, which is wholly or predominantly made of Cellulose-based synthetic fibers, ζ. Β. made of viscose fibers is guided on a treadmill through a briefly diluted lye bath. In the same A damp fiber fleece can also be guided over a system of suction drums. By various processes, which are summarized under the designation of fusion of the fibers a firmly cohesive material-like structure is formed.
Infolge der hohen Saugfähigkeit der Fasern zeigt die das Laugebad verlassende Fasermasse, falls nicht besondere Maßnahmen getroffen werden, ein Mengenverhältnis von Faser zu Lauge bis ι : 10 und noch mehr, was die Weiterverarbeitung erschwert und durch die Beseitigung der Lauge verteuert.Due to the high absorbency of the fibers, the fiber mass leaving the caustic bath shows Unless special measures are taken, a proportion of fiber to lye up to ι: 10 and even more what further processing difficult and made more expensive by the removal of the lye.
Die Verbesserung des neuen Verfahrens besteht darin, daß man die Menge der auf das Faservlies aufzubringenden Alkalilauge dosiert. Dabei kann man dem Faserstoff je nach Durchführung des Verfahrens und je nach der Menge des aufgebrachten Alkalis einen unterschiedlichen Charakter geben. Dieser geht von einem wattigen, weichen, aber schon geschlossenen Material bei Anwendung niedriger Verhältniszahlen von Watte zu Lauge z. B. ι : ι bis hin zu dichtem, stoffartigem Material bei Verhältnissen von 1 :4 fois 1 : 8. Auch ist es nun möglich, die Lauge nur oberflächlich einwirkenThe improvement of the new process consists in the fact that the amount of on the nonwoven fabric dosed alkali lye to be applied. You can use the pulp depending on how the process is carried out and give a different character depending on the amount of alkali applied. This is based on a padded, soft, but already closed material when used low ratios of cotton wool to lye e.g. B. ι: ι to dense, fabric-like material at ratios of 1: 4 it is 1: 8 now possible, the lye only works superficially
zu lassen, so daß der Stoff nur einen geschlossenen saugfähigen Überzug erhält, während die Watte im Innern in ihrem Charakter wenig oder gar nicht verändert wird. Das ist für eine Reihe von Verwendungsmöglichkeiten wertvoll.to leave, so that the fabric only receives a closed absorbent cover, while the wadding in the Little or not at all is changed in its character. That is for a number of uses valuable.
Das Aufbringen und Einwirken des Alkalis in dosierter Menge kann auf verschiedene Weise erfolgen. Bei Verwendung eines Laugebades wie nach dem Hauptpatent muß das Faservlies vor seiner Einführung in dieses stark gepreßt und im gepreßten Zustand durch die Lauge geführt werden. Es gelingt dann, bei kurzer Behandlung ein Mengenverhältnis von Faserstoff zu Alkali herab bis zu etwa ι : 3 zu erreichen. Es werden entweder Netze oder perforierte Bänder aus Metall oder einem anderen laugefesten Material, wie Polyvinylchlorid, ader Absaugtrommeln verwendet.The application and action of the alkali in a dosed amount can take place in various ways. When using a caustic bath as according to the main patent, the fiber fleece must be in front of his Introduction into this strongly pressed and guided in the pressed state through the lye. It succeeds then, with a short treatment, a ratio of pulp to alkali down to about ι: 3 to reach. Either nets or perforated strips made of metal or some other alkali-proof are used Material such as polyvinyl chloride is used for the suction drums.
Noch niedrigere Verhältniszahlen lassen sich erzielen, wenn man auf die Anwendung von Bädern verzichtet und dosierte Mengen Alkali durch Laugeaufdruck oder durch Aufbringen von Lauge in feinst verteilter Form, wie Tröpfchen oder Nebel, dem Vlies zuführt. So gelingt es, auf jedes beliebige Mengenverhältnis bis ι : ι und noch weniger einzustellen.Even lower ratios can be achieved if you do not use baths and use dosed amounts of alkali Lye imprint or by applying lye in finely distributed form, such as droplets or mist, feeds the fleece. It is thus possible to use any quantity ratio up to and including ι: ι less to adjust.
Das Aufdrucken der Lauge kann mittels Walzen mit saugfähiger Oberfläche geschehen. Dazu werden Walzen mit Maschennetzen, porösem Gummi oder porösen Kunststoffen überzogen, die ihrerseits mit Lauge getränkt werden. Man kann auch einen dicken Baumwollüberzug nehmen. Das Aufspritzen oder Aufnebeln erfolgt in üblicher Weise mittels Versprüher bzw. Vernebler.The lye can be printed on by means of rollers with an absorbent surface. For this purpose, rollers are covered with mesh, porous rubber or porous plastics, which in turn are soaked with lye. You can also use a thick cotton cover. The spraying or Aufnebeln in a customary manner by means of atomizer or nebulizer.
Beispiel ιExample ι
Ein stark gepreßtes Krempelband aus Zellwolle wurde zwischen zwei Metallnetzen, die unter starker Zugspannung gehalten waren, durch ein Laugebad von 7,5 °/o Alkali und 220 geführt. Die Dauer der Einwirkung betrug nur 5 Sekunden. Aufgenommen wurde das Vierfache der Fasermenge. Nach Absäuern, Auswaschen und Trocknen lag ein weiches verfestigtes Vlies vor.A strongly pressed carded sliver of staple rayon was conducted between two metal nets, which were kept under strong tensile stress through a brine bath of 7.5 ° / o and 22 alkali 0th The duration of the action was only 5 seconds. Four times the amount of fiber was absorbed. After acidification, washing and drying, a soft, solidified fleece was obtained.
Ein Krempelvlies aus Zellwolle mit 25 % Baumwolle wurde zwischen feinen weitmaschigen Metallnetzen, die auch fortbleiben konnten, unter leichtem Druck zwischen einem Wakenpaar mit porösem Kunststoffüberzug von oben nach unten geleitet. Die Walzen tauchten am unteren Ende des Durchmessers in Laugebäder von 8% Alkali. Die Temperatur betrug i8°. Bei Anwendung von einem Walzenpaar nahm das Vlies die dreifache Menge seines Gewichtes an Lauge auf. Nach der üblichen Behandlung wurde ein offenes, an der Oberfläche gut verfestigtes Vlies erhalten.A carded fleece made of rayon with 25% cotton was placed between fine, wide-meshed metal nets, which could stay away under light pressure between a pair of pegs with porous Plastic coating passed from top to bottom. The rollers popped at the lower end of the diameter in caustic baths of 8% alkali. The temperature was 18 °. When using a The pair of rollers took up three times its weight in lye. According to the usual Treatment resulted in an open, well-bonded fleece on the surface.
Auf ein Zellwollkrempelvlies zwischen zwei Netzen wurde von beiden Seiten her, gegebenenfalls nur einseitig, 7,5°/oige Natronlauge bei einer Temperatur von i8° gleichmäßig aufgesprüht. Das Vlies hatte ein Trockengewicht von 500 g je Quadratmeter. Das Verhältnis der aufgesprühten Laugemenge zum Wattegewicht war 1:1. Das Vlies war nach Absäuern, Auswaschen und Trocknen nur an den Oberflächen verfestigt. Es erwies sich als weich, schmiegsam, hochsaugfähig.On a cardigan fleece between two nets from both sides, if necessary 7.5% sodium hydroxide solution was sprayed evenly on only one side at a temperature of 18 °. That Fleece had a dry weight of 500 g per square meter. The ratio of the amount of lye sprayed on to the weight of the cotton wool was 1: 1. The fleece was only on after acidification, washing and drying solidified the surfaces. It turned out to be soft, pliable, and highly absorbent.
