Abstract
Considering the growing environmental awareness, natural dyeing is considered as a sustainable approach in textile dyeing, which can minimize the environmental impacts of synthetic dyes. In this study, it was aimed to compare the dyeing properties of different cellulose-based fabrics (100% cotton, 100 % viscose, 100% Tencel) with pomegranate bark extract as a natural dye by using two different mordants (potassium aluminium sulfate and iron (II) sulfate). Results revealed that potassium aluminium sulfate (alum) and iron (II) sulfate gave different color shades from light to medium yellowish-brown shades with different color depth (K/S) and color vividness (chroma). Alum mordant resulted in lighter, more greenish and more yellowish shades with more vivid color than iron (II) sulfate. The maximum K/S of 3.5 was achieved with viscose fabric mordanted with iron (II) sulfate. All dyed samples had satisfied color fastness values and increased tensile and tear strength compared to raw fabrics.
