Der Gegenstand der vorliegenden Erfindung betrifft die Verwendung von Tannin zur Verbesserung der Ozonechtheit von gefärbtem und ungefärbtem polyamidhaltigem Material.The object of the present invention relates to the use of tannin for Improvement of the ozone fastness of colored and undyed polyamide-containing material.
Gefärbtes und ungefärbtes polyamidhaltiges Material wie z.B. polyamidhaltiges Fasermaterial, ist bekannterweise empfindlich gegenüber Umwelteinflüssen, wie z.B. Licht-, Hitze- oder Ozoneinwirkung, und muss in der Regel gegen diese stabilisiert werden.Dyed and undyed polyamide-containing material such as polyamide fiber material, is known to be sensitive to environmental influences, e.g. Light, heat or Ozone exposure, and usually must be stabilized against it.
Die gegenwärtig verwendeten Stabilisatoren erfüllen aber die heutigen Anforderungen nicht vollumfänglich.However, the stabilizers currently used do not meet today's requirements fully.
Darum besteht weiterhin ein Bedarf an Mitteln, welche eine den heutigen Anforderungen gerechte Stabilisierung des polyamidhaltigen Materials, insbesondere gegen Ozon, gewährleisten.Therefore, there is still a need for means that meet today's requirements ensure fair stabilization of the polyamide-containing material, especially against ozone.
Es hat sich überraschenderweise gezeigt, dass mit der erfindungsgemässen Verwendung von Tannin eine sehr gute Stabilisierung des polyamidhaltigen Materials gegenüber Ozon erreicht wird.Surprisingly, it has been shown that with the use according to the invention of tannin a very good stabilization of the polyamide-containing material against ozone is achieved.
Gegenstand der vorliegenden Erfindung ist somit die Verwendung von Tannin zur Verbesserung der Ozonechtheit von gefärbtem und ungefärbtem polyamidhaltigem Material, welche dadurch gekennzeichnet ist, dass man Tannin auf das polyamidhaltige Material aufbringt, oder dem polyamidhaltigen Material einverleibt.The present invention thus relates to the use of tannin for improvement the ozone fastness of colored and undyed polyamide-containing material, which characterized in that tannin is applied to the polyamide-containing material, or incorporated into the polyamide-containing material.
Unter dem Begriff Tannin wird in der vorliegenden Anmeldung eine Klasse der natürlichen
Polyphenolen sehr vielfältiger Zusammensetzung verstanden, welche sich strukturell von der
3,4,5-Trihydroxybenzoesäure (sog. Gallussäure) ableiten.
Es sind z.B. die Verbindungen der Formel (sog. Gallotannine)
worin
R unabhängig voneinander einen Rest der Formel
und/oder
worin
n eine Zahl 0, 1 oder 2 ist,

Verfahren, oder in einem Druckverfahren wie z.B. Spritz-, Rotations- oder
Flachdruckverfahren.
Beim diskontinuierlichen Verfahren (Ausziehverfahren) kann das Flottenverhältnis in einem
breiten Bereich gewählt werden, z.B. 1:4 bis 1:100, vorzugsweise 1:6 bis 1:50.
Beim kontinuierlichen Verfahren wird die Flotte auf das polyamidhaltige Material durch beispielsweise
Foulardieren oder Pflatschen aufgebracht werden.
Tannin, bzw. die wässrige Tanninlösung kann dabei auf das zu behandelnde polyamidhaltige
Material in einem beliebigen Behandlungsschritt, z.B. aus einer Vor- oder Nachbehandlungsflotte,
oder vor, während oder nach einem Färbeprozess aus dem Färbebad aufgebracht
werden.Tannin can be applied to the polyamide-containing material by all methods customary in the textile finishing industry, for example in a continuous or discontinuous method, or in a printing method such as, for example, spraying, rotary or planographic printing.
