Abstract (en)

[origin: EP1055763A2] Wet fabrics (1) are steamed after treating with reactive dyes by passing them through superheated steam at 150 to 230 degree in a horizontal path. Steam is blown from jet chambers (15) arranged above and below the fabric. The moisture content of printed fabrics is reduced from 15 - 25% to 3 -7%. The residence time in the chamber (12) is 5 to 60 secs, especially 10 to 20 secs. An Independent claim is also included for a steam treatment chamber (12) with jet chambers (15) and circulating fans (14). fabric (1) is carried through the chamber on a perforated conveyor (41) with 50 to 90% clear area.

Abstract (de)

Beim Farbfixieren von Reaktivfarbstoff auf Zellulose ist es bekannt, eine feuchte Warenbahn ohne Zwischentrocknung mit einem Dampf-Luftgemisch in Kontakt zu bringen. Dabei ist es erforderlich, eine Restfeuchte bis zum Ende des Fixierprozesses aufrecht zu erhalten. Es werden verhältnismäßig lange Fixierzeiten und bei einem kontinuierlichen Verfahren Vorrichtungen mit einem entsprechend hohen Wareninhalt benötigt. Es soll ein Verfahren und eine Vorrichtung entwickelt werden, bei dem kleinere Warenmengen wirtschaftlich, kontinuierlich gefärbt werden können. Erfindungsgemäß wird die Warenbahn mit Behandlungsgas, das im wesentlichen aus Heißdampf besteht, in Kontakt gebracht. Überraschenderweise ermöglicht dies eine schnellere Farbfixierung bei guter Farbausbeute und Farbqualität. Eine für kleinere Warenmengen geeignete Vorrichtung weist eine Transportvorrichtung zum im wesentlichen ebenen Führen der Warenbahn mit einem Walzengang und einer Umluftvorrichtung mit oberhalb und unterhalb der Warenbahn angeordneten Düsenkästen auf. Kontinuierliche Wärmebehandlung einer textilen Warenbahn, insbesondere Farbfixieren. <IMAGE>
