Nature provides materials with coloring sources as well as helping to create the concept of “colorfulness” by presenting images with all of its glory and richness. Although the dyeing methods are improved and applied on threads and fabrics with advanced technologies, using natural sources and natural dyes in the coloring of textiles always had a special place. Natural dyes are obtained from the leaves, flowers, cones, tree barks, roots, suckers, etc. of colorant plants. Although dyeing can be performed with natural dyes, auxiliary products are needed at the same time. These products called mordant provide the dyestuff to fasten on the fibers and to obtain a good color fastness and different color tones from the same plant. In natural dye production, natural wastes draw attention in terms of recycling and its environmental compliance with a clean dyeing technology and increase the importance of natural dyes. At this stage, natural mordants also become important in addition to the natural dyestuffs. Thus, in this study, various parts of the pomegranate plant and dock root and lye natural mordants were used. The aim of the study is to examine the color features of wool and cotton threads that were dyed with natural mordants and the dyestuff obtained from the pell, flower, and leaves of pomegranate plant and to determine the fastness levels. Non-mordanted and simultaneous mordanting methods were used in the dyeing of wool and cotton threads, fastness tests of washing and rubbing were conducted. As a result of the research, pomegranate peel and pomegranate leaf with close color tones are obtained, pomegranate flower is reached with different colors; fastness test results of ash water mordant were found to be higher.
