Es ist bekannt, dass mit Pappreserven bedruckte Gewebe dadurch zum Ausfärben mittels Indigo in der Continueküpe geeignet gemacht werden können, dass man die bedruckte Seite der Gewebe mit konzentrierten Alkalilösungen, die zweckmässig behufs besseren Pflatschens mit etwas Verdickungsmittel versetzt sind, überzieht.

Process for dyeing indigo reserve items in the continuous vat.
It is known that fabrics printed with cardboard reserves can be made suitable for dyeing with indigo in the continuous vat by coating the printed side of the fabric with concentrated alkali solutions, which are expediently mixed with a little thickener for better swabbing. This method
EMI1.1
the tissue is only likely to shrink, but the vat will also become unusable after a short time due to the increasing alkalinity.
According to the present invention, this disadvantage can be avoided by not using alkali solutions for the coating, but rather thickening agents which, such as starch, are sparingly soluble and only weakly dissolve in the alkaline cup.
EMI1.2
The present method is expediently carried out in such a way that the tissue is pre-strengthened in the usual way, but this is not necessary per se
EMI1.3
Thickening that is still insoluble is to be attributed, so that post-finishing can mostly be omitted, which has the advantage that the goods retain their lively blue cast, which is otherwise usually very damaged during the subsequent finishing. The

can.
To produce the protective layer, for. H. the following materials are expediently used:
