ABSTRACT:
The invention provides an improvement in the known dry thermoprinting process making it possible to employ the process to dye or print natural fibers or mixtures of natural and synthetic fibers. Textile material consisting of natural fibers or of a mixture of natural and synthetic fibers is impregnated with a precondensate of a thermosetting resin. The thus impregnated material is then dyed or printed by the dry thermoprinting process, the curing of the resin taking place during the transfer of the dyestuff.
