Dyes

Two natural dyes, alizarin and indigo, have major significance.Alizarin is a red dye extracted from the roots of the madder plant, Rubia tinctorium.Two other red dyes were obtained from scale insects.These include kermes, obtained from Coccus ilicis (or Kermes ilicis), which infects the Kermes oak, and cochineal, obtained from Dactylopius coccus, which lives on prickly pear cactus in Mexico The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased. Dyes colored organic compounds used to color fabrics, leather, furs, paper, plastic, cured rubber, wood, and other materials. Dyes also include colorless compounds from which a colored substance is formed after it is applied to the material.

Unlike most organic compounds, dyes possess colour because they 1) absorb light in the visible spectrum (400-700 nm), 2) have at least one chromophore (colour-bearing group), 3) have a conjugated system, i.e. a structure with alternating double and single bonds, and 4) exhibit resonance of electrons, which is a stabilizing force in organic compounds (Abrahart, 1977) Dyes refer to the organic substances enable the strong coloring of fiber and some other materials. There are various kinds of dyes. According to the source, they can be divided into natural dyes (such as vegetable dyes, animal dyes and mineral dyes, etc.) and synthetic dyes (or artificial dyes) Acid dyes are water-soluble anionic dyes, containing one or more sulfonic acid substituents or other acidic groups. An example of the class is Acid Yellow 36. Acid dyes are applied from acidic dye baths to nylon, silk, wool, and modified acrylics. They are also used to some extent for paper, leather, ink-jet printing, food, and cosmetics

(vii) Vat dyes Vat dyes are the well-known dyes they are insoluble in water and hence cannot be. Azo dyes are organic compounds bearing the functional group R−N=N−R′, in which R and R′ are usually aryl.They are a commercially important family of azo compounds, i.e. compounds containing the linkage C-N=N-C. Azo dyes are widely used to treat textiles, leather articles, and some foods.Chemically related to azo dyes are azo pigments, which are insoluble in water and other solvents dye - dye - Dyeing techniques: Direct, or substantive, dyes are applied to the fabric from a hot aqueous solution of the dye. Under these conditions, the dye is more soluble and the wettability of natural fibres is increased, improving the transport of dye molecules into the fabric. In many cases, the fabric is pretreated with metallic salts or mordants to improve the fastness and to vary the.

A dye is a coloring material that is used for imparting color to different substances or altering the color of something. Dyes have chromophores and auxochromes which are responsible for their color and substantivity The latest tweets from @N_Dye Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources ± roots, berries, bark, leaves, and wood ² and other organic sources such as fungi and lichens. Archaeologists have found evidence of textile dyein Dyes containing one or more azo groups (i.e. azo dyes) comprise by far the largest family of organic dyes. Prominent types are 1) acid dyes for polyamide and protein substrates such as nylon, wool, and silk; 2) disperse dyes for hydrophobic substrates such as polyester and acetate, and 3) direct and reactive dyes for cellulosic substrates such a
