Dyeing Research essay
Chapter I THE PROBLEM Inroduction Dyeing has become part of daily living. For thousands of years, dyeing has been used by humans to decorate clothings and different kinds of fabrics. Its first used can be traced back 5000 years ago in India and Middle East where people used the most the most peculiar sources of the colors of their dyes. Since it’s first used , dyes have been dominating the industry. Before, dye manufacturers were only able to produce one color at a time. But now dyes come in every different colors and type as well.
For its long years of usage, the primary source of dye has been nature obtained from animal, vegetable or mineral origin. But by far, the greatest source of dyes has been the plant kingdom, notably from their roots, bark, leaves, wood and their berries. Malabar night shade ( basella rubra linn), commonly known as alugbati, is a fast-growing, soft-stemmed, branched, twining herbaceous vine with either purplish or green stem. It has fruits or berries that are stalkless, spherical, and purple when mature.
Studies of the pigment extracted from its fruits showed that the intensely purple juice from the fruit contains anthocyanin which is natural food colorant. Background of the Study Dye is common in all of us. In last years, mankind has been able to produced artificial dyes that offer broader range of colors, and render more stable dyes to resist effects of washing and other general use. As the dyeing technology advances, it becomes more costly and expensive. In this case most families had very little to spare for new clothes that had been dyed costly.
To brighten up their clothing, people nowadays can use dye that can be produced in simple ways or methods with the use of Alugbati plants found anywhere in our country. Statement of the Problem The investigation aims to explore the possibility of comingup with berries of the alugbati plant. Specifically, it aims to answer the following questions: 1. Do alugbati berries able to produce fabric dyes? 2. Does the action of the dye produced from the alugbati berries equally competent with the action of commercial dyes to fabric? Hypothesis
The alugbati berries extract can be make a natural fabric dye. Significance of the Study This provides the awareness on the possible use of Alugbati fruit extract as natural fabric dye. The results of the study will be valuable to the community, to the school, and to the researcher itself. It will bring benefits to the entire community because if proven; it will give rise to an inexpensive fabric dye taken only in our locality. Also most of the chemically created colors are terrible poisons compared to the natural fabric dye produced from this common plant.
The results of the study will also serve as basis in determining the potential of alugbati as natural fabric dye. Scope and Limitation of the Study This will conducted at Santa Isabel, Dipolog City this coming September 25, 2009. The fabric dye will be produced through pure extraction from Alugbati fruits which will be compared to the commercially-prepared dye. The action of dyes will be tested on a piece of cotton cloth. Cotton will be used in the study because it can be dyed a range of dye types.
The darkness and the lightness of the color of the resulting dyed clothes will then be compared. The control set-up will be used commercial dyes found in the local market and the experimental set-up will used dye produced from extraction of Alugbati fruits. Each set-up will have 5 replicates and the experiment will have three (3) trials. Definition of Terms Alugbati fruits – refer to the small edible fruit or berry of an alugbati plant.
Anthocyanin – the pigment extracted from fruits of the plants that shows good stability as a potential natural food color. Dye – a colored substance that has an affinity to the substrate to which it is being applied. Dyeing – process of imparting colours to a textile material in loose fibre, yarn, cloth or garment form by treatment with a dye. Extract – refers to the withdrawing juices from alugbati fruits. Natural Fabric Dye – dyes used in clothings or fabrics produced naturally from plants and animals.
