Description

Verfahren zur Herstellung naßfester Gebilde aus regenerierter Cellulose Es wurde gefunden, daB man Gebilde aus regenerierter Cellulose mit besonders guten Eigenschaften in bezug auf Quellfestigkeit erhalten kann, wenn man verätherte und/oder veresterte Methylolverbindungen von Aminotriazinen den Lösungen der Cellulosederivate vor ihrer Regenerierung und Formgebung, vorteilhaft in Form von Emulsionen oder Dispersionen, zusetzt.Process for the production of wet strength structures from regenerated cellulose It has been found that structures made from regenerated cellulose are particularly good Properties related to swelling resistance can be obtained if etherified and / or esterified methylol compounds of aminotriazines and solutions of cellulose derivatives before their regeneration and shaping, advantageously in the form of emulsions or Dispersions, adds.

Als alkoholische Komponente können ein- oder mehrwertige, gesättigte oder ungesättigte, aliphatische oder aromatische Alkohole verwendet werden. Als Veresterungskomponente kommen Carbon-oder Oxycarbonsäurell aliphatischer oder aromatischer Natur in Betracht. Derartige Verbindungen lassen sich in emulgierter Form leicht in der Viscose verteilen. Der Vorteil des Zusatzes dieser thermohärtenden Kunststoffe besteht beispielsweise darin, daB diese bügelfest sind, im auskondensierten Zustand durch Wärmebehandlung keine physikalische Änderung erleiden und keine zusätzlichen Operationen erfordern. Beispiel iooo Teile Viscose mit einem Gehalt voll 6,5 °/o Alphacellulose und 7 °/o NaOH werden mit io Teilen des Verätherungsprodukts aus Hexamethylolmelainin mit 5 NTol Butanol in Emulsionsform versetzt.The alcoholic component can be monovalent or polyvalent, saturated or unsaturated, aliphatic or aromatic alcohols can be used. as Esterification components are carboxylic or oxycarboxylic acids, more aliphatic or aromatic Consider nature. Such compounds can be easily emulsified in emulsified form distribute in the viscose. The advantage of adding these thermosetting plastics consists, for example, in the fact that these are iron-proof in the condensed state do not suffer any physical change and no additional changes due to heat treatment Require operations. Example 10000 parts viscose with a content of 6.5% Alpha cellulose and 7% NaOH are extracted with 10 parts of the etherification product Hexamethylol melainin mixed with 5 NTol butanol in emulsion form.

Anschließend wird die Viscose filtriert, entlüftet und nach der üblichen Reifezeit auf Fäden, Filme oder beliebige andere Gebilde aus regenerierter Cellulose versponnen hzw. verarbeitet.Then the viscose is filtered, deaerated and after the usual Maturing time on threads, films or any other structure made of regenerated cellulose spun hzw. processed.

Die Emulsion, die in die Viscose eingerührt wird, wird wie folgt hergestellt: io Teile Kasein werden in ioo Teilen Wasser mit. 2 Teilen einer 35 o/oigen Natronlauge und 2 Teilen Ammoniak (spezifisches Gewicht o,92) aufgeschlossen. Hierzu rührt man zunächst io Teile einer r o o/oigen Natriumoleatlösung ; alsdann läßt man 3oo Teile einer 50 o/oigen Butanollösung des Verätherungsprodukts von 5 Mol Butanol mit i Mol llexamethylolmelamin zulaufen. Man erhält durch Rühren eine Wasser-iri-01-Einulsion, die so eingestellt wird, daß ioo Teile genau so Teile der alkoholischen Harzlösung enthalten.The emulsion, which is stirred into the viscose, is produced as follows: 100 parts of casein are mixed with 100 parts of water. 2 parts of a 35% sodium hydroxide solution and 2 parts of ammonia (specific weight 0.92) digested. To do this one stirs initially 10 parts of a red sodium oleate solution; then leave 300 parts a 50% butanol solution of the etherification product of 5 mol of butanol with i Mole of llexamethylolmelamine run in. A water-iri-01 emulsion is obtained by stirring, which is set in such a way that 100 parts are exactly the same as parts of the alcoholic resin solution contain.
