Abstract (en)

A process is provided wherein film (e.g. polyester) which has been dyed by at least one disperse dye, is contacted with textile material in the presence of sufficient heat to cause the dye to sublime or vaporize and transfer some of the dye from the film to the textile material, thereby effecting level dyeing of the textile material. Both the film and textile material have affinity for the dye, and softening points which are higher, and glass transition temperatures which are lower, than the temperature needed to effect sublimation or vaporization and transfer of the dye. Also a process is provmed wherein film is continously dyed with at least one disperse dye and thereafter continuously contacted with a textile material at elevated temperature so as to sublime or vaporize the dye and transfer dye from the film to the textile material.
