I. Problem: Will natural dyes from plants effective in producing colored paste? II. Title: Using Natural Dyes form Plants In Producing Colored Paste III. Introduction:
Our project is made from the raw materials such as starch, alum and annatto seeds. One of our reasons in making this project is it can help students save money because our product can be a substitute for glue. It doesn’t cost us too much time because we can make this in a short period of time. IV. Review of Related Literature:
* Our project is somewhat similar with the project of other students from Manresa School Paranaque City. It is about dyeing of fabric through the use of NATURAL DYES FROM PLANTS.
CONTENTS OF THEIR PROJECT:
ABSTRACT
This study aimed to produce natural dye from the extract of mangosteen husks and explore the function of fixing agents (mordants). in the dyeing process. Mangosteen (Garcinia mangostana), a rare fruit known to be the "queen of tropical fruits," contains bitter yellow latex and purple juice. The mangosteen husks, which are put to waste, produce stain. This led to the idea of producing a household product without using harmful chemicals. Literature reveals that mangosteen husks actually contain a substance called tannin, which makes the husks a potential source of natural dye. Using sliced mangosteen husks, an extract was obtained by boiling. The extract was sifted from the solid materials using cheesecloth. A clean, cotton cloth was then subjected to a series of procedures from pretreatment and mordanting down to dyeing with the rnangosteen extract. Alum and copper sulfate were used as mordants. Results revealed that the mangosteen extract was stabilized by both mordants, but copper sulfate was a better fixing agent than alum, because it intensified the color of the extract. It can be concluded that the mangosteen husk extract can
