A process is disclosed for producing cloque or undulating effects on the surfaces of textile fabrics made from synthetics, in which process the fabric is subjected to a first heat-treatment at temperatures varying between 100.degree. C. and 200.degree. C. with tension or pressure being applied, e.g. hot calendering or stentering, for the purpose of temporarily increasing the density of the threads in the fabric. Following this, the fabric is printed with a heat-resistant resist to the specifications of a pattern, and subjected to a second heat-treatment at temperatures varying between 100.degree. C. and 200.degree. C., preferably without tension, for 30 seconds to 10 minutes for the purpose of decreasing the density of the threads in those areas not printed with the resist paste. The resist is removed by washing, the fabric being dried by conventional means.

Process for producing cloque or undulating effects on the surfaces of

Process for dry dyeing and printing of flat textile fabrics containing cellulose fibers with a cross-linking treatment of those fibers in which the fabric is treated with an aqueous solution of cross-linking agents, and auxiliary agents is dyed or printed after pre-drying according to the transfer printing process in dry condition with sublimable dyestuffs and is heated in the presence of an acid or potentially acid catalyst.
