摘要:
The application of liquid to a moving fabric is effected by delivering same to a rotatable spinning disc which centrifugally impells the liquid against the fabric. This action overcomes surface tension causing the liquid droplets to break up into a fine mist so that a large area of fabric is wetted with an amount of liquid which is substantially less than the fabric weight. Also, the velocity imparted to the liquid droplets in mist forms enhances absorption of the liquid by the fabric.

The invention relates to a method for the controlled application of a liquid to a material web (1), in particular for the application of a dyeing liquor to a material web (1), wherein the material web (1) is moved along a running path (2), and the direction of the material web (1) is changed multiple times on the running path (2) thereof by means of deflecting rollers (4, 5, 6, 7, 8, 9). Thus, the material web (1) is guided in running-path segments (10, 11, 12) that are approximately parallel to each other and have opposite running directions (19, 20, 21). The liquid is distributed as drops between the running-path segments (10, 11, 12) by a rotational disk (13, 16) in a rotational plane (30), wherein the drops of the liquid are applied simultaneously to the material-web segment of the first running-path segment (10) running in the one direction and to the material-web segment of the second running-path segment (11) running in the other direction. The second liquid application in the second running-path segment (11) is applied over a first liquid application from the first running-path segment (10). According to the invention, the liquid fed to the rotational disk (13, 16) is a spraying liquor, which is composed of mixing components, wherein the bringing together of the mixing components and the mixture thereof into a spraying liquor occur shortly before the feeding of the spraying liquor to the rotational disk (13, 16).

摘要:
Es ist bekannt, daß die Brillanz der Reaktivfarbstoffe beim Zweiphasen-Kaltverweilverfahren höher ist, als bei jeder anderen Methode. Für den von der Praxis favorisierten Minimalauftrag der Fixierflotten hat sich in erster Linie die Sprühtechnik angeboten. Mit Hilfe von Druckluft-gesteuerten Düsen oder Hochrotations-Flüssigkeitssprühköpfen werden sehr feine Sprühnebei erzeugt, die bei langsamer Bewegung des zu besprühenden Materials wohl auch einen gleichmäßigen Auftrag erbringen. Bei der in der Textilindustrie üblichen Warengeschwindigkeit von 40-80 m/min treten indessen soviel unerwünschte Turbulenzen auf, daß kein gleichmäßiger Auftrag der Präparationen zu erreichen ist. Hochrotations-Flüssigkeitssprühköpfe sowie durch Druckluft gesteuerte Düsen eignen sich ferner nur zum Versprühen dünnflüssiger Präparationen. Darüber hinaus sind sie bei höheren Geschwindigkeiten nur schwer zu steuern und erfordern hohe Investitionskosten für die Anlage. Von der Verfahrenstechnik her gesehen, sind jedoch für den Minimalauftrag höher viskose Lösungen auf Basis von Natronwassergläsern viel besser für das KaltverweilVerfahren geeignet. Erfindungsgemäß wurde nun gefunden, daß sich diese in zufriedenstellender Weise aber nur über Rotoren versprühen lassen, die mit einer Drehzahl von 3000 bis 7000 Umdrehungen je min arbeiten.
