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:
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 effectively be used as an alternative, environment-friendly dye.
Dyes have become part of daily living. What's great about dyes is that they give variety to everything. Even the earliest humans used dyes to put color into their worlds, and they even used the most peculiar sources of the colors. Since then, dyes have dominated different kinds of industries. Before, dye manufacturers were only able to produce one color at a time. But now, dyes come in different colors and types as well. Dyes today are easier to use compared to earlier forms of dyes, because previous dye makers got their materials from animals, minerals, or any other common things that were never thought could produce colors. This study is stimulated by queries such as how colored substances got their color and how do these colors last on fabrics. This investigation aimed to explore the possibility of coming up with an effective product from recycled materials through the use of mangosteen husk extract to produce dye. The mangosteen fruit is capped by the prominent calyx at the stem end. It is a round and smooth fruit with dark-purple to red-purple covering. It also contains bitter yellow latex and purple staining juice that can leave marks on hands and clothes. The fruit is commonly consumed without giving any thought on thehusks. It can be noticed that peeling the fruit already produces color. Intentionally extracting the stain from the husk (cortex) might produce a good dye.
Mangosteen husks were separated from the edible parts of mangosteen fruits (one kilogram) obtained from a local market. The husks were rinsed under running water to get rid of the impurities. The husks were then towel-dried and sliced into small pieces to allow better penetration of the dye. After cutting, the husks were weighed using a triple beam balance. Approximately 500 g of manizosteen husks were boiled in water (30 milliliters (mL) of water is required per gram of husks). The mixture was strained using cheesecloth to get rid of the fruit fibers that were still present. The...
