The Effect of Metal-ion Addition to Natural Dyes
Some plants contain well-known pigments that have been used as coloring agents in textile industry. However, the availability of natural dyes to give a color variation is very limited and considered as less practical. It is known that some metal ions can interact with plant's pigment and result...
