Embodiments).  

Bei dem erfindungsgemäßen Verfahren handelt es sich um die Verwendung überkritischer Fluide, auch als "superkritische Fluide oder überkritische bzw. superkritische Gase bezeichnet", bzw. von verflüssigten Gasen als Trägermedium (Fluid) für den das Fasermaterial bzw. auf das textile Substrat aufzubringenden Wirkstoff. Aus diesem Trägermedium läßt sich der Wirkstoff unter Variation der Verfahrensparameter (Druck, Temperatur) auf bzw. in den jeweiligen Fasermaterialien bzw. textilen Substraten abscheiden. Unter überkritischen Fluiden sind solche, ursprünglich gasförmigen oder flüssigen Systeme zu verstehen, die durch entsprechende Änderung des Druckes und Änderung der Temperatur über ihren kritischen Punkt gebracht werden. Hier nehmen solche fluiden Systeme besondere Löseeigenschaften an.The method according to the invention involves the use of supercritical ones Fluids, also called "supercritical fluids or supercritical or called supercritical gases ", or of liquefied gases as a carrier medium (Fluid) for the fiber material to be applied or onto the textile substrate Active ingredient.

Hierbei bewirkt der Zusatz eines hydrophoben Lichtschutzmittels außerdem, daß in Art einer Carrier-Färbung bei ansonsten gleichen Verfahrensbedingungen ein tieferer Farbton an der Ware erzielt wird.There are other ways to increase the comfort of clothing textiles in the possibility of using insect repellent in the fiber material to bring in what is particularly interesting for casual clothing. Similarly, UV absorbers can be anchored to the textile. This may help Hats, hats or other casual clothing a certain sun protection for the user as well as for the fiber material are incorporated. A such a light-protecting effect can be carried out simultaneously with a coloring will. The addition of a hydrophobic light stabilizer moreover, that in the manner of a carrier stain, otherwise the same Process conditions a deeper shade of the goods is achieved.

Darüber hinaus lassen sich etwa Bakterizide und Fungizide etc. aufbringen, was für den Einsatz in medizinischen Bereichen (Kliniken) genutzt werden kann, derart etwa daß Verbandsmaterial u. a. sterilisierend oder mit den Heilungsprozeß fördernden Wirkstoffen beladen werden. Ähnliches gilt ebenso für das Aufbringen etwa antibakterieller Wirkstoffe auf Wischtücher und -vliese etc. in solchen Fällen kommt die schon bei der Parfümierung angesprochene Depotwirkung zum Tragen. Im technischen Textilsektor können analog etwa Antifoulingmittel mit Langzeitwirkung am bzw. im Textil verankert werden.In addition, bactericides and fungicides etc. can be applied, what can be used for use in medical areas (clinics) can, such as that dressing material u. a. sterilizing or with the Active ingredients promoting the healing process are loaded. The same applies for applying antibacterial agents to wipes and fleece etc. in such cases comes the one already mentioned during the perfuming Depot effect to carry. In the technical textile sector, analog such as long-acting antifouling agents anchored on or in the textile will.

Als Vorteil des erfindungsgemäßen Verfahrens ist anzuführen, daß die Wirkstoffe (z. B. Spinnpräparation, Schlichten bzw. Avivagen) in besonders gleichmäßiger Verteilung auf Fasermaterialien bzw. die textilen Substrate aufgebracht werden kann, wodurch sich besondere Verarbeitungsvorteile ergeben.An advantage of the process according to the invention is that the active ingredients (e.g. spin finish, finishing or finishing) in particular even distribution on fiber materials or the textile substrates can be applied, which results in special processing advantages.
