Abstract

Transfer printing of polyester fabrics using disperse dye vapors is performed by contacting the un-dyed polyester fabrics (receptor) with other heavily dyed polyester fabrics (donor) under the influence of heat and pressure, a technique well known as heat transfer printing. The evolved disperse dye vapors will flow across the small air gap existing between the inner donor and receptor surfaces. Studies revealed that the dye uptake by the receptor fabrics is dependent on the original disperse dye content of the donor fabrics as well as, the transfer printing conditions, (temperature, time). Subsequently the released dye from the donor fabrics strongly depend on the amount of dye present originally. It was proved also that the dyed polyester donor fabrics could be used multiple times producing prints having similar color strength values to a certain extent. The possibility of application of the process as continuous process was also investigated. The color fastness and mechanical properties of the prints were assessed and found to be acceptable.
