A PROCESS OF IMPROVING THE DYEABILITY AND MINIMIZING THE PILLING EFFECTS IN A SYNTHETIC POLYESTER TEXTILE MATERIAL COMPRISING A CONDENSATION POLYMER OF TEREPHTHALIC ACID AND ETHYLENE GLYCOL, COMPRISING THE STEPS OF IMMERSING THE TEXTILE MATERIAL IN A HEATED, ANYDROUS, RELATIVELY HIGH-BOILING, WATER-SOLUBLE, INERT, ORGANIC LIQUID MEDIUM IN THE SUBSTANTIAL ABSENCE OF ANY DYESTUFF AND AT AN ELEVATED TEMPERATURE OF AT LEAST 250*F. BUT BELOW THE SOFTENING POINT OF THE TEXTILE MATERIAL, FOR A PERIOD OF TIME SUFFICIENT TO EFFECT IMPREGNATION OF THE TEXTILE MATERIAL WITH THE HEATED ORGANIC LIQUID MEDIUM AND TO MODIFY THE FIBER STRUCTURE OF THE TEXTILE MATERIAL BY PENETRATION OF SAID ORGANIC LIQUID MEDIUM INTO SAID FIBER STRUCTURE BUT WITHOUT OTHERWISE AFFECTING THE FIBER STRUCTURE, REMOVING THE TEXTILE MATERIAL FROM THE HEATED ORGANIC LIQUID MEDIUM, AND IMMEDIATELY THEREAFTER CONTACTING THE TEXTILE MATERIAL WITH RELATIVELY COOL WATER, THEREBY SUBSTANTIALLY REMOVING THE ADHERING ORGANIC LIQUID MEDIUM FROM THE TEXTILE MATERIAL WHILE LEAVING ENTRAPPED WITHIN THE FIBER STRUCTURE THEREOF A SMALL RESIDUAL AMOUNT OF SAID ORGANIC LIQUID MEDIUM.
