Determination of Color Properties of Dyed Textile Products Using Different Mordanting Methods

Abstract

In this research, we investigated the dyestuff properties of dwarf elderberry (Sambucus ebulus), which has many pharmacological functions. Dyeing of cotton fabrics and wool yarns was carried out using Sambucus ebulus L. fruit extracts. Textile products were processed to pre–, meta–, and post– mordanting methods in the presence of iron sulfate (FeSO4), copper sulfate (CuSO4) and alum (AlK(SO4)2) mordants. Color analyses of dyed textile products were performed and, the results were examined in terms of washing, rubbing, and light fastness. According to the results, it was determined that wool yarns showed better dyeing potential than that of cotton fabrics in terms of washing fastness. While the highest K/S value was measured as 6.55 in cotton fabrics with the pre-mordanting method, the highest K/S value was measured as 14.90 in wool yarns. In addition, the highest color strength values were obtained in each three mordanting methods. While gray, beige, and cream color tones were obtained in dyeing cotton fabrics, beige, green, and gray color tones were obtained in dyeing wool yarns.
