Title StatementPigments from the sweet potato (Ipomoea batatas) tuber as a substitute for commercial textile dye
Physical Description21p
Summary, Etc.Ever since synthetic dyes were created, they have become the most popular coloring material for clothes and textiles. They soon begun to get cheaper and easier to produce. Our study aims to use sweet potato peelings for the production of a dye which can match or surpass the quality of commercial synthetic dyes. For the preparation of the cloth, we mixed 100 grams of potassium aluminum sulfate, or alum, and 25 grams of cream of tartar in 200 ml of cold water. We learned that the optimal binding time for cloth is approximately 1 hour. To make the dye, sweet potatoes were gathered and weighed (3 kilograms of potatoes have about 25 grams of peelings). These were added to 300 ml of water and boiled in an enamel pot. The given mixture yielded 75 ml of dye. Using the same methodology, we were able to perform three trials. The first trial produced a very nice color; however, it was not able to fasten to the cloth and was washed off, probably because of a low concentration of mordant. The dye in the second trial, although it fastened, was not able to yield a satisfactory color. Our third trial resulted in a dye that had both a good color and strong bond to the cloth. However, it was not spread evenly, which was probably due to the placement of the cloth. The results suggested that  the boiling time and the mordant mixture qualities of the sweet potatoes had an effect on the final product
