Dyes from Philippine Plants

Dyes from Philippine Plants

 

Dyeing using different plants has been a traditional practice. However, with the invention of

artificial dyes and modern dyeing practices, such use of dyes from plants was soon

abandoned.

 

There are many Philippine plants which 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, such as: 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.

Nursery Plant Pots from Coconut Coir

Nursery Plant Pots from Coconut Coir

 

Plants grow faster in pots made of coconut husk with coconut dust than in soil. For example,

nursery plants like:

 

1. Asparagus springerie – grown in coconut husk with equal amounts of dust and swine

marine had more cuttings than those planted in rice field with swine manure.

 

2. Anthurium – more flowers per plant.

 

3. Dracaena fragrans (leafy plant) – increased roots

 

4. Mussaendes – longer roots (with spagnum moss and coconut) during marcotting.

 

5. Amherstia nobilis – faster marcotting even without the use of growth hormones.

Lumber from Coconut Tree

Lumber from Coconut Tree

 

Studies showed that wood from matured coconut trees when cut into 50 mm thick can be

used for housing and furniture materials.

 

To ensure that the wood does not get deformed, the lower part of the tree is cut and allowed

to dry in the air.

 

During summer, drying takes about 11-14 weeks and 16-17 weeks on rainy days.

The Many Uses of Barks

The Many Uses of Barks

 

The term bark loosely refers to the outer covering of the stem and branches. Technically, it

includes all the tissues from outside the cambium to the outermost layers of a woody stem.

The bark serves as a protective tissue. It acts as a conduit transporting food to the other parts

of the tree. About 8% of the total volume of a tree in bark.

 

Bark consists of an outermost corky layer called epidermis, a layer of manufactured

food-conducting tissues called phloem, a zone between these two layers known as cortex. In

several species, a layer of fibrous strips called “bast fiber” forms an innerbark. Oils, resins,

tannins, waxes and phenolic substances may be present in the bark.
