CONCLUSION

Problem:


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


9/16

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.

ConclusionOur hypothesis was right. The

texture of the paper out of

Malunggay Bark is rough. It isacceptable in the market, and it will

be cheap if sold, because thematerials are not expensive.
