Özet: One of the most important problems of natural dyeing is lack of raw material. In the recent years, researchers are aimed to solve the deficiency of raw material. The pulp of plants which are obtained from the steam distillation, are used as a dyestuff. We assume that the dyestuff in pulp of oregano and sage after steam distillation remain stable. Wool yarns and silk fabrics have been dyed in previous works done as a master and a Proficiency in Art thesis. The results were showed that our assumption is correct. Based on these results further researches were done. The textile materials were dyed with %100 of pulp of oregano and sage.  Mordant dyeing method was applied and three different mordant materials were applied with pre-mordant process. Alum [Kal(SO4)2.12H2O], ferrous (II) sulphate [FeSO4.7H2O] and potassium dichromate [K2Cr2O7] were used as a mordant and potassium bitartrate [KC4H5O6] as an auxiliary agent in alum mordanting. Rubbing (dry and wet) and washing fastness values were determined. Also the depths of shade were evaluated in terms of K/S and CIELAB colour difference values of the dyed fabric samples.                         According to the results obtained from the dyeing, the capability of pulp of plants is adequate and will supply the lack of the dyestuff. While the colors obtained from silk and wool fabrics are more vivid and dark, the colors of cotton fabrics are quite pale. This study will allow other pulp of plants to be evaluated in this way.
