The quality of Jatropha leaf ecoprint products using steaming and pounding techniques

Abstract

Abstract A new technique in textile coloring, namely the ecoprint dyeing technique, has emerged which further proves the development of the textile industry. There are several techniques of ecoprint which are steaming technique, pounding technique and boiling technique. To produce a good eco print color, one must consider the ecoprint coloring technique, the type of textile material used, the type of mordant substance, the mass of the mordant substance, and the length of the coloring process. Mordant alum is more widely used as a fixator because it is easier to obtain and more affordable. Meanwhile, one of the natural coloring substances that can be used as natural dye is Jatropha leaves (Jatropha curcas L.). Researchers then further revealed the use of Jatropha leaves to color the textile because it has the potential to be used as natural fiber-based dyes for textiles. The independent variable used in this study is the ecoprint technique, including steaming (X1), pounding (X2), and boiling (X3). Meanwhile, the dependent variable is the quality of eco prints results with indicators including: colors difference and darkness. The data analysis method used in this research is descriptive and inferential statistics. The dyeing process on cotton cloth using alum fixation treatment and the bottom pounding method resulting the highest color darkness compared to other coloring methods. The bottom pounding method produces the darkest color. Statistical results of ANOVA test showed that there was a significant effect on the test results.
