3/16
What will be the texture, cost value,and acceptance in the market of paper
if recycled wood bark of malunggay isused in making it?
Hypothesis
We think that if recycled wood bark ofmalunggay is used in making paper,then its texture will be rough, it is
cheap, and it will be acceptable in the
market.

ProceduresI. Preparation of materials
The barks of Malunggay stems are
removed. The outer skin was scraped off and bark wasstripped off from the inner wood. Then the barks weresun-dried. The materials were first prepared before theexperiment.
Procedures
II. Boiling of Malunggay Barks
The dried barks were boiled in caustic sodaand water for 2-3 hours. Then the barks were washed to

remove chemicals. They were then pounded to produceood pulp.
II. B. The barks were washed toRemove chemicals.
II. C. Then pounded to produceWood pulp.
ProceduresIII. Bleaching and Dyeing of the Wood Pulp
The pulp produced in the process was bleachedusing chlorine. After bleaching, it was washed toremove chemicals. The wood pulp was soaked in
ater for 5-15 minutes to make it whiter. Then

the wood pulp was boiled in dye and water forabout 15 minutes.
ProceduresIV. Molding and Drying of Wood Pulp
The dyed wood pulp can now be molded.Using the mold and deckle, the wood pulp mixed with
ater was molded. To dry the pulp, place it on an evenall or screen to let it dry. When the pulp has already
dried, strip off the paper from the wall.

After we had produced the paperout of the Malunggay Bark, we
asked somebody to rate the tearstrength, texture and acceptance ofthe paper.

Malunggay Bark is rough. It isacceptable in the market, and it will
be cheap if sold, because thematerials are not expensive.
