Description

Im Patent 938 724 wird, die Hydropbilierung von Gebilden aus synthetischen Polyamiden durch Behandlung mit einer wäßrig-alkoholischen Emulsion von mit löslichen Polyestern emulgierten Mischpolyamiden und nachherigem Erhitzen beschrieben.In patent 938,724, the hydropilation of Formed from synthetic polyamides by treatment with an aqueous-alcoholic emulsion of copolyamides emulsified with soluble polyesters and subsequent heating.

Es wurde gefunden, daß man die Saugfähigkeit von Textilien aus synthetischen linearen Polyamiden dadurch erhöhen kann, daß man die Textilien mit wäßrig-alkoholischen kolloidalen Emulsionen behandelt, die neben einem mindestens in heißem Wasser löslichen Polyester ein nunmehr am Stickstoff methoxymethyliertes synthetisches Polyamid enthält, worauf das getrocknete Gut auf Temperaturen über 100° vorzugsweise auf 105° erhitzt wird.It has been found that the absorbency of textiles made of synthetic linear polyamides is thereby can increase the fact that the textiles are treated with aqueous-alcoholic colloidal emulsions, in addition to a polyester which is at least soluble in hot water, a now methoxymethylated at nitrogen Synthetic polyamide contains, whereupon the dried goods to temperatures above 100 ° is preferably heated to 105 °.

Die Erfindung beruht auf der Beobachtung, daß am Stickstoff methoxymethylierte Polyamide sich mittels solcher Polyester in alkoholhaltigem Wasser leicht zu beständigen kolloiden Emulsionen verarbeiten lassen. Taucht man in solche Emulsionen Textilien aus synthetischen linearen Polyamiden, so ziehen die nunmehr verwendeten Methoxymethylpolyamide in feiner Form auf. Es ist auch nicht mehr notwendig, hierbei zu erwärmen oder irgendwelche besonderen Zusätze zu verwenden. Eine Verklebung der in die Lösung bzw. Emulsion eingeführten Textilien findet nicht statt. Werden die Textilien alsdann auf über 100° erhitzt, so werden die aufgebrachten Methoxymethylpolyamide darauf fixiert, und die Textilien werden hydrophil.The invention is based on the observation that polyamides methoxymethylated on nitrogen are by means of Such polyester can easily be processed into stable colloidal emulsions in water containing alcohol. If one dips textiles made of synthetic linear polyamides into such emulsions, they now pull used methoxymethyl polyamides in fine form. It is also no longer necessary here to heat or use any special additives. A sticking of the in the solution or emulsion imported textiles does not take place. If the textiles are then to over 100 ° heated, the applied methoxymethyl polyamides are fixed on it, and the textiles are hydrophilic.

Ein \^orteil des erfindungsgemäßen Verfahrens besteht darin, daß auch wenig einheitliche Methoxymethylpolyamide sowie solche niedrigen Substitutionsgrades verwendet werden können. Zweckmäßig läßt man hierbei die Emulsion des Methoxymethylpolyamids solange stehen, bis die infolge Gelatinierung der weniger löslichen Anteile trübe geworden ist, und filtriert die Lösung dann unter Zusatz von Filtrationshilfsmitteln, z. B. Tierkohle. There is one advantage of the method according to the invention in that there are also poorly uniform methoxymethyl polyamides and those with a low degree of substitution can be used. It is expedient to leave the methoxymethyl polyamide emulsion here stand until the less soluble parts have become cloudy due to gelatinization, and the solution then filtered with the addition of filtration aids, e.g. B. animal charcoal.

Weiter hat es sich als vorteilhaft erwiesen, aus den Emulsionen der Methoxymethylpolyamide die schweremulgierbaren Anteile abzutrennen, was z. B. durch Wasserzusatz geschehen kann. Verwendet man die verbleibende Emulsion für die Behandlung von Textilien, so ist es möglich, auch mit hartem Wasser zu arbeiten, was die Aufarbeitung erleichtert.It has also proven advantageous to use the emulsions of the methoxymethyl polyamides which are difficult to emulsify Separate shares, which z. B. can be done by adding water. If you use the remaining emulsion for the treatment of textiles, so it is possible to use hard water too work, which facilitates the processing.

Beispiel 1example 1

4 Mol Glykol und 1 Mol Bernsteinsäure werden in Gegenwart von 10 Gewichtsprozent eines Sulfonsäuregruppen enthaltenden Ionenaustauschers als Katalysator 16 Stunden auf 150° erhitzt. Das filtrierte Reaktionsgemisch enthält je Mol ursprünglicher Säure noch 0,0612 Mol Säure und ist wasserlöslich.4 moles of glycol and 1 mole of succinic acid are added in the presence of 10 percent by weight of a sulfonic acid group containing ion exchanger as a catalyst heated to 150 ° for 16 hours. That filtered The reaction mixture contains 0.0612 mol of acid per mol of original acid and is water-soluble.

60 g eines methoxymethylierten Polyamids aus Caprolactam, welches zu 10% substituiert ist und noch 45 g Wasser enthält, und 120 g des wie vorstehend erhaltenen Reaktionsgemisches werden mit 1200 ecm Methanol vermischt. Nach etwa 14 Tagen wird der Ansatz mit Tierkohle versetzt und filtriert. Je 50 Teile des Filtrates werden mit 38 Teilen Wasser versetzt, der Niederschlag unter Zusatz von Tierkohle filtriert und das Filtrat in die 10- bis 20fache Menge Leitungswasser von der Gesamthärte 21° gegossen. Es bildet sich eine milchige Emulsion; sie wird nach 20 bis 30 Minuten durch ein Tuch filtriert. In die Emulsion werden Fasern aus ε-Caprolactam hergestelltem Polyamid eingebracht und geschüttelt. Die Emulsion zieht rasch auf die Fasern auf ohne sie zu verkleben. Die Fasern werden vorsichtig abgeschleudert und eine Stunde auf 105° erhitzt. Auf eine Steinplatte ausgeschüttetes Wasser kann mit den Fasern ähnlich wie mit einem Löschpapier aufgesaugt werden. Unbehandelte Fasern schieben das Wasser vor sich her.60 g of a methoxymethylated polyamide from caprolactam, which is 10% substituted and still contains 45 g of water, and 120 g of the reaction mixture obtained as above are with 1200 ecm of methanol mixed. After about 14 days, animal charcoal is added and the mixture is filtered. 38 parts of water are added to 50 parts of the filtrate and animal charcoal is added to the precipitate filtered and the filtrate poured into 10 to 20 times the amount of tap water with a total hardness of 21 °. A milky emulsion forms; it is filtered through a cloth after 20 to 30 minutes. In the Emulsion are fibers made from ε-caprolactam Polyamide introduced and shaken. The emulsion is quickly absorbed by the fibers without sticking them together. The fibers are carefully spun off and heated to 105 ° for one hour. On a stone slab Spilled water can be soaked up with the fibers in a similar way to blotting paper. Untreated Fibers push the water in front of them.
