The highest water consumption in textile sector is in finishing processes. The usage amount of clean water in dyeing processes are very high. In addition to this the wastewater released after dyeing processes is also have high environmental waste load. Recent studies have focused on less water usage and recovery of the water used more effectively. In this direction, environmental studies become a current issue. Gas bubbles in the liquid having a diameter of microns or less increase the mobility of water molecules by moving slowly towards the water surface in the water. These bubbles, called micro and nano bubbles, are produced in water by air and oxygen suspension method. In this way, high quality results have been achieved in many industrial applications. In this thesis, 1% and 4% disperse dyes were made with dyes of different molecular sizes using bubble waters produced by air and oxygen suspension method. The fabrics to be dyed were produced by knitting with 3 different turns / m twist and 3 different yarn fineness and the color and fastness values were examined. Results were interpreted by comparing the sample dyed by conventional methods.
