The study utilized natural dye extracted from orange peel to color Tencel fabric samples, with pre-mordanting and post-mordanting methods using ferrous sulfate and copper sulfate. Colorfastness was evaluated according to ISO standards, showing that the best color depth was achieved with ferrous sulfate post-mordanting. All dyed samples exhibited good lightfastness, with ferrous sulfate displaying better lightfastness compared to copper sulfate. Rubbing fastness results favored copper sulfate, while both mordants showed similar washing fastness and no structural changes were observed in the FTIR test. Additionally, TGA indicated stability up to 300°C.
The usage of natural dyes for coloration has attained attention in recent years due to their ecofriendly environment. Therefore, in this study, orange peel solvent extract is used as a natural dye for coloring Tencel fabric samples. Pre-mordanting and post-mordanting methods were accomplished with two different mordants, i.e. ferrous sulfate and copper sulfate. The dyeing shade effects were retrieved through colorfastness properties according to the ISO standardizations. The results revealed that the best color shade (K/S: 4.56) was achieved using mordant ferrous sulfate through the post-mordanting method. The effect of lightfastness on all dyed Tencel fabric samples was observed good (3-4) in both mordanting methods. However, mordant ferrous sulfate showed better lightfastness (4) than copper sulfate (3-3.5) through both mordanting methods. Comparatively, in the rubbing fastness, copper sulfate has superior results in both mordanting methods. The ferrous and copper sulfates in both mordanting methods have similar tests results (4.5) of washing fastness, acidic and alkaline perspiration. Furthermore, the FTIR test substantiated that not any structural change occurred through orange peel dyed Tencel fabric samples through both methods. TGA observed samples were relatively stable up to 300(circle)C temperature. Overall, the best results of colorfastness for Tencel fabric samples were obtained with ferrous sulfate mordant through the post-mordanting extraction method.
