The impact of the use of different mordants types on the ecoprint dyeing using secang wood (Caesalpinia sappan Linn) dye on primisima fabric

The purposes of this study are (1) to determine the effect of mordants tawas, tunjung, and tannins on the ecoprint dyeing result using secang (caesalpina sappan linn) wood dye on primisima fabrics (2) to find the best results in ecoprint dyeing using different types of mordants including the pattern clarity, color sharpness, color fairness, and color absorption. The method of this research is experimental. The independent variables are mordants tawas, tunjung, and tannins. The dependent variables are the ecoprint dyeing results including the pattern clarity, color sharpness, color fairness, and color absorption. The control variables are secang (caesalpina sappan linn) wood dye, mordanting technique, and primisima fabric. The data of the study were collected by using observation. There were 6 ecoprint treatment samples used in the design of this study, i.e. sample A - using mordants tawas on the main fabric, secang (caesalpina sappan linn) wood dye on blanket, and mordants tawas in the fixation; sample B - using mordants tawas on the main fabric, secang (caesalpina sappan linn) wood dye on the blanket, and mordants tunjung in the fixation; sample C - using mordants tunjung on the main fabric, secang (caesalpina sappan linn) wood dye on the blanket, and mordants tawas in the fixation; sample D - using mordants tunjung on the main fabric, secang (caesalpina sappan linn) wood dye on the blanket, and mordants tunjung in the fixation; sample E - using mordants tannin on the main fabric, secang (caesalpina sappan linn) wood dye on the blanket, and mordants tawas in the fixation; and sample F - using mordants tannin on the main fabric, secang (caesalpina sappan linn) wood dye on the blanket, and mordants tunjung in the fixation. The analysis results show that: (1). Based on the pattern clarity test, sample C and E have the clearest pattern, which is 4,55 and 4,575 respectively. Sample A has a “clear” pattern, which is 4.25. Sample D and F have an “average” pattern, which are 3,775 and 3,525. Sample B has a “less clear” pattern, which is 2,775. (2) Based on the color sharpness test, sample C has the sharpest pattern, which is 4,55. Sample E has a “sharp” pattern, which is 4,25. Sample A and D have an “average” color sharpness, which is 3,25. Meanwhile, samples B and F also have “average” color sharpness, which are 2,525 and 2,825 respectively. (3) Based on the color fairness test, sample E has the fairest color, which is 4,05. Sample C and D have “fair” colors, wh
