Then you had to wash them in the washing machine for approximately thirty- eight minutes, with one fourth cup of Tide Simply fresh and Clean detergent, Then the materials dried over night, for the best results. The next day we put them in a sixteen ounce glass jar with the dye and two tablespoons of

Learning about the Art of Fashion Draping Fashion draping is the oldest method in fashion design, and it has been used since the 18th century.

chosen? Recent studies have found that certain dyes can cause hyperactivity in children and even pose certain serious health risks like cancer and tumors. Some such dyes include Yellow 5, Red 40, and Yellow 6 - dyes that are not only found in many foods but more commonly in widely consumed candies which are not normally noticed by those who eat them. By using chromatography, you can test to find out if your favorite candy contains these harmful dyes. In this lab, our hypothesis was proven for the

Did you know that diamonds can have different colors and not only It’s colorless white one? Unfortunately, those are really rare and will cost much more than the colorless ones. But, they are able to be colored by being lab-grown, with an affordable price too. Buying a synthetic diamond is better than buying a natural one because of its environmental sustainability, price, and also the knowledge that your diamond did not support war or labor in any way. One trait of synthetic diamonds is being

A dye is a coloured substance that has an affinity, a bond with a physical surface, to the substrate to which it is being applied. Dyes are usually soluble in water. Dyes are used to change the perceived colour of an object. Dyes consist of 2 main parts: chromohore and auxochrome. Before 1856, all dyes were obtained from natural resources. The first synthetic dye, Mauveine, was accidentally discovered by William Henry Perkin in 1856 while he was looking for a cure for malaria. Different dyes are

To demonstrate synthesis of Indigo through the Baeyer-Drewson reaction, and subsequent vat dying of cotton through conversion to and from Leucoindigo. Indigo (Vat Blue 1) is a vat dye with a molecular formula of C16H10N2O2. A characteristic of vat dyes is that they are insoluble in most aqueous environments. A reducing agent is required to convert them into a soluble “leuco” form, meaning “white” or colourless. The dye can subsequently be reversed back into its original coloured form through oxidation

DYEING Dyes are coloring materials used in dyeing textiles. Other hand it can be defined as a substance which may be natural or synthetic use to change or add color to the textile materials. They are incorporated into the fiber by chemical reaction, absorption, or dispersion. Dyes differ in their resistance to sunlight, perspiration, washing, gas, alkalizes, and other agents; their affinity for different fibers; their reaction to cleaning agents and methods; and their solubility and method of application

Introduction: Benzopinacol can be prepared from benzophenone in presence of sun light (photochemically) using isopropanol as the reducing agent in presence of acetic acid. Acetic acid is added to prevent the cleavage of benzopinacol to benzophenone and benzhydrol by the alkali derived from the glass container used for the reaction. Benzopinacol obtained in the first experiment is converted to benzopinacolone by heating under reflux (5 minutes) with glacial acetic acid containing trace amount of iodine

natural dyes. The dyes include sources that may seem unusual. The colour red used in the zone Mixtec-Zapotec comes from the cochineal, the insect, which is referred to by the friar Bernardino de Sahagún in the sixteenth century.
