Aus der belgischen Patentschrift 752 668 und der deutschen Auslegeschrift 1 253 449 ist es bereits bekannt, Copolyamide auf Basis 65-Aminoundecansäure einerseits und Laurinlactam andererseits 31Hn Verkleben von Textilien zu verwenden. Diese Schmelzkleber auf Basis von 60-Aminoundecansäure und Laurinlaotam sind jedoch neben anderen Mangeln mit dem Nachteil behaftet, daß die zu ihrer Herstellung erforderlichen Ausgangsmaterialien schwer zugänglich sind.From Belgian patent specification 752 668 and German Auslegeschrift 1 253 449 it is already known to use copolyamides based on 65-aminoundecanoic acid on the one hand and laurolactam on the other hand 3 1 Hn bonding of textiles. However, these hot-melt adhesives based on 60-aminoundecanoic acid and laurollaotam have the disadvantage, along with other deficiencies, that the starting materials required for their production are difficult to access.
Überraschenderweise wurde nun gefunden, daß man unter Verwendung der genannten Nachteile gemäß der Erfindung Schmelzkleber auf Basis von Copolyamiden erhält, die sich durch hohe Klebefestigkeit, geringe Wasseraufnahme, gute Waschbeständigkeit gegen Seifenlaugen und Beständigkeit gegenüber bestimmten organischen Lösungsmitteln, insbesondere chlorierten Kohlenwasserstoffen auszeichnen.Surprisingly, it has now been found that, using the disadvantages mentioned, according to the invention, hot-melt adhesives based on copolyamides, which are characterized by high adhesive strength, low water absorption, good wash resistance against soapy water and resistance to certain organic solvents, especially chlorinated solvents Label hydrocarbons.
Die erfindungsgemäßen Schmelzkleber sind dadurch gekennzeichnet, daß sie aus Copolyamiden aus 20 bis 40 Gewichtsprozent 6-Caprolactam, 10 bis 30 Gewichtsprozent Adipinsäure - Hexanethylendiaminsalz und 30 bis 50 Gewichtsprozent Dodecandisäure - ac, 62-Diaminsalz bestehen, cc, (*> -Diamine im Sinne der Erfindung sind aliphatische, bzw. cycloaliphatische Diamine, beispielsweise Hexamethylendiamin, Trishexamethylendiamin, 4 ,4 '-Diaminodicyclohexylmethaii und 2,2,4-Trimethylhexamethylendiamin. Die Produkte eignen sich in Pulverform besonders zum Verleimen von Textilien .in der Hitze.The hot-melt adhesives according to the invention are characterized in that they consist of copolyamides of 20 to 40 percent by weight 6-caprolactam, 10 to 30 percent by weight adipic acid - hexanethylenediamine salt and 30 to 50 percent by weight dodecanedioic acid - ac, 62-diamine salt, cc, (*> -diamine in the sense of the invention are aliphatic or cycloaliphatic diamines, for example hexamethylenediamine, trishexamethylenediamine, 4,4'-diaminodicyclohexylmethaii and 2,2,4-trimethylhexamethylenediamine.The products are particularly suitable in powder form for gluing textiles in the heat.

Die Hersteilung der Copolyamide wird vorteilhafterweise so durchgeführt, daß das Copolyamid einen Kondensationsgrad aufweist, der einem K-Wert nach Pikentscher (1-gewichtsprozentig in konzentrierter Schwefelsäure) von 40 bis 65 entspricht. Der Kondensationsgrad kann durch Zugabe eines Kettenreglers wie z.B. einer monofunktionellen Carbonsäure, z.B. Stearinsäure bzw. Propionsäure, vor der Polykondensation eingestellt werden,The preparation of the copolyamides is advantageous carried out so that the copolyamide has a degree of condensation which has a K value according to Pikentscher (1 percent by weight in concentrated sulfuric acid) from 40 to 65. The degree of condensation can be adjusted by adding a Chain regulator such as a monofunctional carboxylic acid, e.g. stearic acid or propionic acid, before the polycondensation be set,
Die Erfindung ist nachstehend anhand eines Beispiels näher erläutert.The invention is explained in more detail below using an example.

Zur Vorkondensation wurde auf 27O0C unter Eigendruck (20 atü) erhitzt und das Reaktionsgemisch 1 Stunde bei dieser Temperatur gehalten» Anschließend wurde innerhalb von 2 Stunden auf Normaldruck entspannt. Zur Nachkondensation wurde das Reaktionsgemisch weitere 2 Stunden im Stickstoffstrom auf 27O0C erhitzt. Das getrocknete Granulat wies einen K-Wert (1-gewichtsprozentig in konzentrierter Schwefelsäure) von 56 und einen Meltindex von 55 g/10 Minuten bei 1900C auf.given. For the pre-condensation (20 atm) was heated to 27O 0 C under autogenous pressure the reaction mixture is heated and "held for 1 hour at this temperature then was depressurized within 2 hours at atmospheric pressure. For post-condensation, the reaction mixture was heated an additional 2 hours in a nitrogen stream at 27O 0 C. The dried granules had a K value (1 percent by weight in concentrated sulfuric acid) of 56 and a melt index of 55 g / 10 minutes at 190 0 C.
