A dye can generally be described as a colored substance that has an affinity to the substrate to which it is being applied. The dye is usually used as an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. In contrast, a pigment generally has no affinity for the substrate, and is insoluble. Archaeological evidence shows that, particularly in India and the Middle East, dyeing has been carried out for over 5000 years. The dyes were obtained from either animal, vegetable or mineral origin, ...

The first man-made organic dye, mauveine, was discovered by William Henry Perkin in 1856. Many thousands of dyes have since been prepared and, because of vastly improved properties imparted upon the dyed materials, quickly replaced the traditional natural dyes. Dyes are now classified according to how they are used in the dyeing process. Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dyebaths. Attachment to the fiber is attributed, ...

Vat dyes are an ancient class of dye, based on the original natural dye, Indigo, which is now produced synthetically. Both cotton and wool, as well as other fibers, can be dyed with vat dyes. Not all vat dyeing is done with vat dyes! "Vat dyeing" means dyeing in a bucket or vat. It can be done whenever a solid even shade, the same color over the entire garment, is wanted, using almost any dye, including fiber reactive dye, direct dye, acid dye, etc. The opposite of vat dyeing is direct dye application, such as, for example, tie dyeing

Acid dye is a member of a class of dye that is applied from an acidic solution. In the home or art studio, the acid used in the dyebath is often vinegar or citric acid. In textiles, acid dyes are effective on protein fibers, i.e. animal hair fibers like wool, alpaca and mohair. They are also effective on silk. They have little or no effect on plant-based or synthetic fibers. Acid dyes sound scary to some novices, who imagine that the dyes themselves are caustic strong acids. In fact, the dyes are non-caustic, are non-tox ...

A carbene dye is a reactive dye based on carbene chemistry. A benzophenone is functionalised with a chromophore or group that can be easily converted to a chromophore at a later stage. The functionalised benzophenone is reacted with hydrazine hydrate and subsequently treatment with mercury oxide. The resulting Diazo compound is stable at room temperature. On heating, Nitrogen gas is released and the Carbene generated. The thus generated carbene reacts rapidly with substra ...

Tyrian purple is a purple dye made in the ancient Phoenician city of Tyre from a secretion of Spiny Dye-Murex (Murex brandaris), a marine snail. A similar dye, "Hyacinth Purple" was made from the related Banded Dye-Murex Murex trunculus. The dye was expensive: Aristotle assigns a value ten to twenty times its weight in gold. The fast, non-fading dye was an item of luxury trade, prized by Romans, who used it to colour ceremonial robes. Pliny the Elder described the dyeing process of two purples in his Nat ...

Anodising, or anodizing, is a process used to protect aluminum from abrasion and corrosion and to allow it to be dyed in a wide range of colors. The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process. Anodized aluminum can be found on paintball guns, carabiners, and other extreme sports equipment due to its aesthetic propertie ...

Cochineal is an expensive crimson or carmine dye derived from the cochineal insect (Dactylopius coccus), a scale insect in the suborder Homoptera, native to tropical and subtropical South America and Mexico. This article covers both the dye and the insect; the latter also is sometimes called simply "cochineal". A primarily sessile parasite, the cochineal insect lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid to deter predation by other ...

A water cannon is a device that shoots a high-pressure stream of water. Typically, water cannons deliver a large volume of water, often over hundreds of feet (tens of metres). Water cannon - Fireboats. Water cannons were first devised for use on fireboats. Putting out fires on boats and buildings close to the water was much more difficult and dangerous prior to the invention of fireboats. The first fire boat deployed in Los Angeles was commissioned on August 1, 1919. The first fire boat in New York City was ...

Indigo is a challenging dye to use because it is not soluble in water; to be dissolved, it must undergo a chemical change. When a submerged fabric is removed from the dyebath, the indigo quickly combines with oxygen in the air and reverts to its insoluble form. When it first became widely available in Europe in the sixteenth century, European dyers and printers struggled with indigo because of this distinctive property. It was also a toxic substance that, by requiring many ch ...

Cudbear is a dye extracted from orchil lichens that produces colours in the purple range. It can be used to dye wool and silk, without the use of mordant. Orchil, or orcein, also called Archil, is another name for a purple dye obtained from lichen. It was the "poor person's purple", used instead of overpriced Tyrian purple, or as an initial "bottom" dye to greatly reduce the consumption of Tyrian purple. Use of orchil dyes was ...

Colored smoke is a kind of smoke created by an aerosol of small particles of a suitable pigment or dye. Colored smoke can be used for smoke signals, often in military. It can be produced by smoke grenades, or by various other purotechnical devices. The mixture used for producing colored smoke is usually a cooler-burning formula based on potassium chlorate oxidizer, lactose or dextrin as a fuel, and one or more dyes, with about 40-50% content of the dye. 2% of sodium bicarbonate may be a ...

Lawsonia inermis Henna is a dye found in hair coloring, that is also used in a temporary body art known as mehndi. It is made from the dried leaf and petiole of Lawsonia alba Lam. (Lawsonia inermis L.). The dye is traditionally found in India, Pakistan, Iran, and North Africa—as well as in expatriate communities from these countries. The American Food and Drug Administration has not approved henna for direct application to the skin, but only for adding a deep red tint and shine to hair. Most ...
