aus Polyamidenmade of polyamides

Es ist bekannt, daß die Saugfähigkeit von Polyamiden, insbesondere des Polyamids aus Hexamethylendiamin und Adipinsäure durch Behandeln mit Emulsionen von Polymethylmethylolhexamethylendiaminadipat, in schwach sauren wäßrigen Alkohollösungen und nachherigem Trocknen erhöht wird, wobei die hydrophilen Eigenschaften nicht zuletzt auf die Methylmethylolgruppen des auf dem Gut zurückbleibenden Methylolderivates zurückgeführt werden.It is known that the absorbency of polyamides, especially the polyamide from hexamethylenediamine and adipic acid by treating with emulsions of polymethylmethylolhexamethylenediamine adipate, in weakly acidic aqueous alcohol solutions and subsequent drying is increased, the hydrophilic properties not least on the methylmethylol groups of the methylol derivative remaining on the property to be led back.

Es wurde nun gefunden, daß überraschenderweise die einfacher gewinnbaren, alkohollöslichen Mischpolyamide, wie sie z. B. in an sich bekannter Weise aus Caprolactam, Hexamethylendiamin und Adipinsäure hergestellt werden können, sich zur Erhöhung der Saugfähigkeit von Polyamiden, insbesondere für Fäden aus dem Polyamid der Aminocapronsäure verwenden lassen, wenn die Polyamidgebilde, wie Fasern oder Gewebe, in Gegenwart zumindest eines wenigstens in heißem Wasser löslichen Polyesters von mittlerem Molekulargewicht mit einer Emulsion eines Mischpolyamides in schwach angesäuertem Wasser oder wäßrigem Alkohol behandelt werden.It has now been found that, surprisingly, the more easily obtainable, alcohol-soluble Mixed polyamides, as they are, for. B. in a known manner from caprolactam, hexamethylenediamine and Adipic acid can be produced to increase the absorbency of polyamides, in particular can be used for threads made of the polyamide of aminocaproic acid, if the polyamide structures, such as fibers or fabrics, in the presence of at least one at least one soluble in hot water Medium molecular weight polyester with an emulsion of a mixed polyamide in weakly acidified water or aqueous alcohol.

Beispielexample

4 Teile eines zu 5o°/o aus Caprolactam und zu 50 0Zo aus adipinsaurem Hexamethylendiamin hergestellten Mischpolyamides, 10 Teile Glykol, 180 Teile Methanol, 25 Teile Wasser und 10 Teile Polybernsteinsäureglykolester werden schwach erwärmt, bis eine klare Lösung erhalten wird, und dann in 1500 bis 4500 Teile vorteilhaft kalkfreies Wasser gegossen. Die Flüssigkeit wird auf 300 erwärmt, schwach angesäuert, z. B. durch Zusatz von 3 bis 4 Teilen einer organischen Säure wie Essigsäure oder Zitronensäure, und es werden 750 Teile eines Gewirkes von Polyamidfäden (180 den) darin etwa 20 Minuten langsam auf etwa 45 bis 500 angewärmt, dann geschleudert und über ioo° getrocknet. Die Ware zeigt eine große Saugfähigkeit, die durch Waschen mit Seife noch erhöht wird.4 parts of a copolyamide prepared to 5o% from caprolactam and 50 0 Zo from adipic acid hexamethylenediamine, 10 parts glycol, 180 parts methanol, 25 parts water and 10 parts polysuccinic acid glycol ester are gently warmed until a clear solution is obtained, and then in 1500 to 4500 parts advantageously poured lime-free water. The liquid is warmed to 30 0 , weakly acidified, e.g. B. by adding 3 to 4 parts of an organic acid such as acetic acid or citric acid, and there are 750 parts of a knitted fabric of polyamide threads (180 den) slowly warmed in about 20 minutes to about 45 to 50 0 , then spun and dried over 100 ° . The goods show great absorbency, which is increased by washing with soap.

Das unbehandelte Gewirke ließ z. B. einen darauf gebrachten Wassertropfen erst nach 64,6 Sekunden hindurchtreten, und die befeuchtete Stelle hatte einen Durchmesser von 5 mm. Die gleiche Ware, erfindungsgemäß behandelt, ließ einen gleich großen Tropfen in 0,4 Sekunden hindurch, und die befeuchtete Stelle nahm einen Durchmesser von 23 mm an. Ein entsprechendes unbehandeltes Gewirke aus regenerierter Zellulose läßt einen Wassertropfen in 3 Sekunden hindurchtreten, und der Durchmesser des befeuchteten Fleckens beträgt 15 mm.The untreated knitted fabric was z. B. a drop of water placed on it only after 64.6 seconds pass through, and the moistened area was 5 mm in diameter. The same goods, Treated according to the invention, let a drop of the same size through in 0.4 seconds, and the moistened Place assumed a diameter of 23 mm. A corresponding untreated knitted fabric regenerated cellulose allows a drop of water to pass through in 3 seconds, and the diameter of the moistened patch is 15 mm.
