Batik, an Indonesian cultural textile heritage, is a technique of wax-resist dyeing applied to whole cloth, or cloth made using this technique.
There are 2 kinds of dyes, there are synthetic dyes and natural dyes.
These are some properties of Batik according to each dye.
More varied, bright
Biodegradable
There are some weaknesses in the natural dye-making process, such as unpredictable colour spectrum.
Thus there is a need for natural dyes made with a different method resulting in a more predictable colour spectrum.
All raw materials were cut into small parts to have a wider surface area so that it could produce the best dye-making result. This research compares the current common method which is the boiling of raw materials with water with a ratio of 1:10 until the ratio of raw materials and water is 1:5. This research introduces a new method to make a natural dye by utilizing The Van Der Walls force which is the attraction of molecules to each other by their polarity. The rst solvent is from the most non-polar solvent (n-Hexane), the second a semi-polar solvent (Ethyl acetate), and the last is the most polar solvent (Ethanol). The nal ltrate is then use for the natural dyes. The Spectrophotometric UV-Vis Analysis is used to compare the spectrum of the colours and the amount of substances. And also, there is a cotton textile visual analysis to compare how well the dyes penetrate the cotton.
The characteristic of Secang is sensitive to the pH level. The more acid it is, the yellower it becomes , and he more base it is, the more purple it becomes.
The ltrate from the boiling method of Suji leaves could not produce the same bright green color as the ltrate from the multilevel extraction.
No Special Characteristics.
