The aim of this study is to investigate the effects of new advanced processes (ultrasound, ozonation, and ultraviolet) on cotton woven fabric's hydrophility and polymerization degrees, breaking strengths, whiteness, and desizing degrees. For this purpose, all trials were realized with water at 63-65°C by the aid of advanced processes. At the end of the experiments, it was noticed that advanced processes can be used in pretreatment of cotton fabrics. Ultrasonic treatment followed by ozonation gives sufficient whiteness degrees and hydrophilily values to the fabric. At the same time, treatment of cotton fabrics with new processes provides savings of thermal energy, water, and chemicals. Moreover, these processes are considered as green processes because they are ecological in certain conditions when compared with conventional processes.

Natural dyes are the heritage of the history to human being. Although they were used for the colouration of goods from the ancient time, it is not common to use natural dyes commercially now. But at least in some special goods it is saving its popularities too. On the other hand, it can be foreseen that the demand on the ecological, natural and organic products in all consumable articles will make natural dyes popular again. Owing to this, it is important to continue the studies on the usability of natural dyes in textile colouration techniques. This study is focused on the printing of natural dyes differently on dyeing with natural dyes. For this aim four different natural sources were used. For the printing process, pigment printing was selected and the printing was managed on wool and cotton fabrics without use of any mordants. The colour values and the fastnesses of prints were evaluated. It was observed that the natural dyes can be used in pigment printing processes and different colour values with different fastnesses could be observed.
