INTRODUCTION

   Try to imagine your world without surrounding hues. It is very
difficult. It is very hard to picture our world without different shades.
Colors make the world come to life. It gives our surrounding its dynamism. If
colors make the world alive, how do we create colors? This is where dyeing
comes in. Dyeing is one in all the oldest ways in which we tend to provide
colors to boring, bland or blank objects.

   The primitive world was more colorful than we
could think. According to KeyColour (August 15, 2016) An initial record of
fabric dyeing goes back to “BC” epoch. Primarily, dyes were created
using natural hues combined with two other liquid which are water and oil. Main
functions of dye in the old days were for skin, jewelry and clothing
decoration. Another important use for dye back then was for painting.

  
Nowadays, almost all of clothing produced is dyed synthetically.
Synthetic dye, which is produced through chemical methods, is one of the two
main types of dyes, the other being natural dye. Sadly, according to Chequer
et. al (2013), chemical dyeing causes significant human health issues and
environmental hazards.

   The
re-discovery of natural dyes for staining which is eco-friendly and
biodegradable has been carefully considered. Plants yield many colors for
dyeing. There are certain trees and herbs especially fruit that produces
dyestuff (Sujata and Saxena, 2014).

      There have been numerous attempts to use
natural process in extracting dye from natural resources. Take this research
from hindawi.com as an example. It states “A new source of natural
anthocyanins dyes, from lily turfs (liriope platyphylla fruit), is proposed.
This paper analyzes the dye extracts, the primary color components of the
extracts, the color features etc.”

      Another good reference would be a research
from the Journal of the Microscopy Society of Thailand, which has their topic
as, Extraction of Natural Histological Dye from Black Plum Fruit. What they did
was to apply color to animal liver tissue by extracting natural dye from plum.
Their research shows how effective natural dye when applied to biological
tissues.

     From
history and these references alone we can claim that the use of fruits as
natural dyes is definitely feasible.

    
The use of natural dyes for staining from alternative sources such as
fruits will greatly reduce the cost for consumers for purchasing synthetic
dyes. More important, this will lower the effects of synthetic dyes on human
and environment.

 

Objectives of the Study

  Therefore, the objective of this study is to
investigate the extraction of natural dye from fruits and how effective it is
when applied.

 

Statement of the Problem

   The primary purpose of this research is to anchor
on existing studies on fruit extracts as dyes to prove the efficacy of dragon
fruit extract. The problems that seeks answers are:

1.    How can the dragon fruit dye be
described in terms of:

1.1.  color;

1.2.  preparation time;

1.3.  ease of use.

2.    Is it viable to the consumers?

  

METHODS AND TECHNIQUES

            In this scientific study, the
researchers will follow the matrix below in order to test the feasibility of dragon fruit (Hylocereus Undatus) as a source of
natural dye.

 

            In the first part of the study, the
researchers will extract the pigment of name of fruit using the steps provided
in the appendix of this research. For part two of this research, the
researchers will then apply the pigment extracted to a cloth. The third step is
that researchers will then get a similar cloth and will apply the same color of
readily available pigment. In this manner, the researchers will be able to see
if there are differences in the researcher-made dye with the readily available
dye in terms of the following parameters: (1) color, (2) preparation time and
(3) ease of use.
