The printing properties, colour strength, effect of particle size, and antibacterial activity of new synthesized dyes for printing of two types of polyester fabrics and polyamide fabric by the heat transfer as well as the silk screen printing techniques have been investigated. The prints obtained have good sublimation properties, high colour strength as well as very good fastness properties. Reduce the particle size of the dyes leads to increase the colour strength. The type of fabric has a great effect on the colour strength of the prints especially in screen printing technique.
