ABSTRACT:
Process for the fixation of prints with reactive dyestuffs, wherein an aqueous alkaline bath which contains an inflammable organic liquid is applied onto the printed and dried material, the said organic liquid is burned off after passage of the material through air and the said material is further treated in the usual manner. This process has the advantage, in addition to the usual advantages of a continuous method of operation over a discontinuous method, that special steamers for the fixation are not necessary. The burning off process is effected in an essentially simpler apparatus, in the most simple case a burning-off duct is sufficient. Moreover, the new process requires less energy than the conventional fixing processes.
