Verfahren zur Herstellung von künstlichen Schwämmen aus regenerierter Cellulose und so hergestellter Schwamm
Verfahren zur Herstellung von künstlichen Schwämmen aus regenerierter Cellulose, wobei die Schwämme mit einem Desinfektionsmittel behandelt werden, um Angriff derselben durch Bakterien und Schimmel vorzubeugen, sind bereits bekannt.
Gemäss einem dieser Verfahren wird der künstliche Schwamm aus regenerierter Cellulose mit einem Reaktionsprodukt von wasserlöslichen Polyacrylsäuren und quaternären Ammoniumverbindungen mit einem hohen Molekulargewicht behandelt.
Die so behandelten Schwämme werden während des Gebrauchs zwar praktisch nicht von Bakterien und Schimmeln angegriffen, aber sie haben den Nachteil, dass sie durch die Verwendung einen Teil ihrer Elastizität verlieren.
Es wurde nun ein Verfahren zur Behandlung von künstlichen Schwämmen aus regenerierter Cellulose gefunden, wodurch diese Schwämme ebensowenig von Bakterien und Schimmeln angegriffen werden. Die erfindungsgemäss behandelten Schwämme weisen daneben den Vorteil auf, dass sie nach längerem Gebrauch ihre Elastizität praktisch nicht verlieren.
Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass die Schwämme mit Carboxymethylcellulose bzw. deren Alkalimetallsalzen und einer quarternären Ammoniumverbindung mit hohem Molekulargewicht und keimtötender Wirkung behandelt werden.
Die Behandlung der Schwämme mit dem Reaktionsprodukt kann dabei auf zwei Weisen erfolgen.
Man kann die Schwämme z. B. zunächst mit einer Lösung von Carboxymethylcellulose oder deren Alkalimetallsalzen in Wasser und sodann mit einer Lösung einer quaternären Ammoniumverbindung in Wasser behandeln. Man kann aber die Behandlung auch in umgekehrter Reihenfolge stattfinden lassen.
Es hat sich gezeigt, dass das Reaktionsprodukt von Carboxymethylcellulose und quaternärer Ammoniumverbindung an der regenerierten Cellulose haftet.
Deshalb bleibt während des Gebrauchs das Reaktionsprodukt im Schwamm und lässt sich denn auch durch Wasser nicht entfernen.
Als Alkalimetallsalz von Carboxymethylcellulose kommt vorzugsweise Natriumcarboxymethylcellulose in Betracht.
Als quaternäre Ammoniumverbindungen mit einer keimtötenden Wirkung kommen z. B. in Betracht
Cetyltrimethylammoniumbromid,
Cetyldimethyläthylammoniumbromid, Stearyknmethylammoniumbromid,
Lauryltriäthylammoniumchlorid,
Octadecenyldimethyläthylammoniumbromid,
Octadecyldimethylbenzylammoniumbromid,
Cetyldimethylbenzylammoniumchlorid,
Lauryldimethylbenzylammoniumchlorid,
Diisobutylkresoxyäthoxyäthyldimethylbenzyl- ammoniumchlorid und Diisobutylphenoxyäthoxyäthyldimethylbenzyl- ammoniumchlorid.
Beispiel I
Aus Viskose hergestellte künstliche Schwämme (25 Stück) wurden sofort nach ihrer Herstellung zentrifugiert. Die zentrifugierten Schwämme wurden zunächst mit einer 1,0 gew.0/oiigen Lösung in Wasser von Natriumcarboxymethylcellulose mit einer Viskosität von etwa 4 centipoise bei 200 C behandelt.
Die Schwämme wurden, nachdem sie zentrifugiert waren, mit einer 1,0 gew.0/eigen Lösung in Wasser von Lauryltriäthylammoniumchlorid behandelt und schliesslich mit Wasser gespült und wieder zentrifugiert.
Diese Schwämme wurden zugleich mit 25 nicht behandelten Schwämmen während 8 Monaten zum Waschen von Autos gebraucht. Danach wurden die Schwämme bezüglich der folgenden Punkte beurteilt: Geruch, Elastizität, Angriff und Äusseres. Die Resultate sind in Tabelle I angegeben.
Tabelle I muffig ohne Elastizität angegriffen mit äusseren Schäden Unbehandelte Schwämme 16 6 7 13 Behandelte Schwämme 2 0 2 2
Beispiel II
25 aus Viskose hergestellte künstliche, trockene Schwämme wurden mit einer 1 gew.0/oigen Lösung in Wasser von Diisobutylphenoxyäthoxyäthyldimethyl- ibenzyiammoniumchlortd - Monohydrat behandelt.
Nachdem sie zentrifugiert waren, wurden sie mit einer 1 gew.0/oigen Lösung in Wasser von Natriumcarboxymethylcellulose mit einer Viskosität von etwa 4 centipoise bei 20O C behandelt. Die so behandelten Schwämme wurden sodann mit Wasser gespült, zentrifugiert und getrocknet.
Diese Schwämme wurden zugleich mit 25 unbehandelten Schwämmen während 8 Monaten als Autoschwamm gebraucht.
Die Schwämme wurden wie oben erwähnt beurteilt (siehe Tabelle II).
Process for the production of artificial sponges from regenerated cellulose and sponge produced in this way
Processes for the production of artificial sponges from regenerated cellulose, the sponges being treated with a disinfectant in order to prevent attack by bacteria and mold, are already known.
According to one of these processes, the artificial sponge made of regenerated cellulose is treated with a reaction product of water-soluble polyacrylic acids and quaternary ammonium compounds with a high molecular weight.
Although the sponges treated in this way are practically not attacked by bacteria and molds during use, they have the disadvantage that they lose some of their elasticity through use.
A method has now been found for treating artificial sponges made from regenerated cellulose, as a result of which these sponges are just as little attacked by bacteria and mold. The sponges treated according to the invention also have the advantage that they practically do not lose their elasticity after prolonged use.
The method according to the invention is characterized in that the sponges are treated with carboxymethyl cellulose or its alkali metal salts and a quaternary ammonium compound with a high molecular weight and a germicidal effect.
The sponges can be treated with the reaction product in two ways.
You can use the sponges z. B. treat first with a solution of carboxymethyl cellulose or its alkali metal salts in water and then with a solution of a quaternary ammonium compound in water. But you can also let the treatment take place in reverse order.
It has been found that the reaction product of carboxymethyl cellulose and quaternary ammonium compound adheres to the regenerated cellulose.
Therefore, the reaction product remains in the sponge during use and cannot be removed by water.
Sodium carboxymethyl cellulose is preferably used as the alkali metal salt of carboxymethyl cellulose.
As quaternary ammonium compounds with a germicidal effect z. B. into consideration
Cetyltrimethylammonium bromide,
Cetyldimethylethylammonium bromide, stearyknmethylammonium bromide,
Lauryltriethylammonium chloride,
Octadecenyldimethylethylammonium bromide,
Octadecyldimethylbenzylammonium bromide,
Cetyldimethylbenzylammonium chloride,
Lauryldimethylbenzylammonium chloride,
Diisobutylcresoxyethoxyethyldimethylbenzylammonium chloride and diisobutylphenoxyethoxyethyldimethylbenzylammonium chloride.
Example I.
Artificial sponges (25 pieces) made of viscose were centrifuged immediately after they were made. The centrifuged sponges were first treated with a 1.0% by weight solution in water of sodium carboxymethyl cellulose having a viscosity of about 4 centipoise at 200.degree.
After they had been centrifuged, the sponges were treated with a 1.0% by weight / own solution in water of lauryltriethylammonium chloride and finally rinsed with water and centrifuged again.
These sponges were used together with 25 untreated sponges for 8 months for washing cars. Thereafter, the sponges were evaluated on the following items: odor, elasticity, attack and appearance. The results are given in Table I.
Table I musty without elasticity attacked with external damage Untreated sponges 16 6 7 13 Treated sponges 2 0 2 2
Example II
25 artificial, dry sponges made from viscose were treated with a 1% strength by weight solution in water of diisobutylphenoxyethoxyethyldimethyl-ibenzyiammonium-chlorod-monohydrate.
After centrifugation, they were treated with a 1% by weight solution in water of sodium carboxymethyl cellulose having a viscosity of about 4 centipoise at 20 ° C. The sponges treated in this way were then rinsed with water, centrifuged and dried.
These sponges were used as car sponges for 8 months at the same time as 25 untreated sponges.
The sponges were evaluated as mentioned above (see Table II).
