ABSTRACT:
Apparatus for applying dyestuffs to textile materials by transfer of the dyestuffs sublimated at reduced pressure, characterized in that it comprises a cooling roll for cooling heated, printed or dyed material to temperatures lower than its secondary transition point and, if desired, further comprises at least one of a pre-heating roll for lessening the temperature gradient between the surface and reverse sides of the textile material to be printed when transfer printing is effected on a heating roll, a brushing roll for remedying deformed, printed textile material and a means for controlling the feeding rates of a transfer printing paper and a backing paper with respect to each other thereby to minimize the difference in peripheral velocity on the heating roll between the printing paper and backing paper.
