Dyeing polyesters

A dye concentrate for dyeing polyesters is prepared by mixing a dye and a relatively small amount of the polyester to be dyed. The mixture is then heated to heat-set the mixture. By so doing, satisfactory feed rates can be maintained to an extruder to allow usable film products to be made.
