dyes were well known in the past for their dyeing properties and have remained in use even now, albeit on a small scale. A renewed interest in natural dyes has increased their commercial availability. Some such important dyes reported in many publications [6, 19, 26] are listed below. Blue Dyes Indigo is the only important natural blue dye. The book identifies plants with high dye content that are viable for commercial use, and provides valuable quantitative information regarding extraction and fastness properties, to aid dye selection. The book presents newer natural dyes in detail, according to their suitability for cotton fabrics, silk fabrics, and wool yarn, before describing.

  The meticulous environmental standards in textiles and garments imposed by countries cautious about nature and health protection are reviving interest in the application of natural dyes in dyeing of textile materials. The toxic and allergic reactions of synthetic dyes are compelling the people to think about natural dyes. Natural dyes are renewable source of colouring materials. Dyes and pigments are the most important colorants used to add a color or to change the color of something. They are widely used in the textile, pharmaceutical, food, cosmetics, plastics, paint, ink, photographic and paper industries. Dyes are.

  The present reference work on Industrial Dyes provides a comprehensive review of the chemistry, properties and applications of the most important groups of industrial dyes, including optical brighteners. It also outlines the latest developments in the area of functional dyes. Azo dyes are the most widely used class of organic dyes for textile dyeing [7,8], corrosion inhibition [9][10][11][12][13], pH and metallochromic indicators [14], sensitizers [15], liquid crystal.

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.

Logwood extract is used in both the oxidized and unoxidised forms. The unoxidised haematein is used for weighting and dyeing of silk, nylon, furs, skins, wood, and straws in black shades. The oxidized haematein is used to dye. After dyeing, oxidation is carried out to restore parent non-ionic dye structure; sulphur dye-cellulose attachment is established through physical forces with dye aggregation occurring in situ.

The Dyes are classified based on the fibers to which they can be applied and the chemical nature of each dye. Dyes are complex unsaturated aromatic compounds fulfilling characteristics like intense color, solubility, Substantiveness, and fastness.

Dyes can be defined as the different type of coloring particles which differ in each type from the other in chemical composition and are used for.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 dyeing.The combination of haematoxylin/haematein with eosin--an aniline dye--was first proposed in in a publication by Poole, forming one of the most used combinations in histology today.

InGeorge N. Papanicolaou introduced a five-dye combination, known simply as the "Pap" stain, destined to become the most commonly used in cytology and.
