Organic Dyes

Leave a comment

Dyeing using different plants  has been a traditional practice.  However, with the invention of artificial  dyes and modern dyeing practices, such use of organic dyes from plants soon lost its popularity.

Many plants in the Philippines  are good source of dyes – either bark or wood.

There are plants which are naturally rich in tannic acid or tannin which is  used in dyeing leather, wood or textile. These are kamachili, bakauan, red  white lauan, tangal, ipil-ipil, coconut husk and others.

The common procedure of extracting dyes is as follows:

1. Boil the ground or chopped bark in uncovered cooking pot with just enough  water to cover the barks.

2. Boil to 60°C-80°C with with continuous  stirring.

3. After an hour, strain in wire screen and replace water in the  cooking pot. Repeat 1-3 until water becomes pale in color.

4. The water used  in second or third boiling could be used for the next fresh barks.

5. Mix  all the water used for boiling and boil them altogether until you get a dark  colored dye.
