Influence of Plasma Modification of Natural Fabrics on the Disperse Dye Fastness

The paper describes methods for preparing natural fabrics for direct printing. The influence of preliminary plasma treatment of natural fabrics on color fastness to washing has been studied. Cotton fabrics and Tencel fabric made from eucalyptus fibers have been examined. Plasma treatment was used to modify the fabrics. The plasma type was nonequilibrium, low-temperature; capacitively coupled radiofrequency discharge plasma in air. It has been established that the plasma treatment of the fabrics in air at a power of 2000 W helps to increase color fastness to washing by up to 82%.
