Brazilwood also gave purple shades with vitriol ( sulfuric acid ) or potash. 49 Choctaw artists traditionally used maple ( Acer.) to create lavender and purple dyes. 32 Purples can also be derived from lichens, and from the berries of White Bryony from the northern Rocky mountain states and mulberry ( morus nigra ) (with an acid mordant). 50 Browns edit cutch is an ancient brown dye from the wood of acacia trees, particularly Acacia catechu, used in India for dyeing cotton. Cutch gives gray-browns with an iron mordant and olive-browns with copper. 51 Black walnut ( Juglans nigra ) is used by Cherokee artists to produce a deep brown approaching black. 31 Today black walnut is primarily used to dye baskets but has been used in the past for fabrics and deerhide.

India is believed to be the oldest center of indigo dyeing in the Old World. It was a primary supplier of indigo dye to europe as early as the Greco-roman era. The association of India with indigo is reflected in the Greek word for the dye, which was indikon (ινδικόν). The romans used the term indicum, which passed into Italian dialect and eventually into English as the word indigo. 46 In Central and south America, the important blue dyes were añil ( Indigofera suffruticosa ) and Natal indigo ( Indigofera arrecta ). 46 47 In temperate climates including Europe, indigo was obtained primarily from woad ( Isatis tinctoria an indigenous plant of Assyria and the levant which has been grown in Northern Europe over 2,000 years, although from the 18th century it was mostly replaced by superior. Woad was carried to new England in the 17th century and used extensively in America until native stands of indigo were discovered in Florida and the carolinas. In Sumatra, indigo dye is extracted from some species of Marsdenia. Other indigo-bearing dye plants include dyer's knotweed ( Polygonum tinctorum ) from Japan and the coasts of China, protein and the west African shrub Lonchocarpus cyanescens. 46 48 Natural dyeing with Indigo, jaipur (Rajasthan, India) edit badshah miyan is a traditional dyer from jaipur who specializes in traditional natural dyeing methods A traditional brass container used to dye cloth in quantity Indigo stains skin a deep blue for many days Purples. Madder could also produce purples when used with alum.

41 This in turn fell out of fashion in the 18th century in favor of the brighter Saxon green, dyed with indigo and fustic. Soft olive greens are also achieved when textiles dyed yellow are treated with an iron mordant. The dull green cloth father's common to the Iron Age halstatt culture shows traces of iron, and was possibly colored by boiling yellow-dyed cloth in an iron pot. 44 Indigenous peoples of the northwest Plateau in North America used lichen to dye corn husk bags a sea green. 45 navajo textile artist Nonabah Gorman Bryan developed a two-step process for creating green dye. First the Churro wool yarn is dyed yellow with sagebrush, artemisia tridentata, and then it is soaked in black dye afterbath. 34 Red onion skins are also used by navajo dyers to produce green. 37 Blues edit Blue colorants around the world were derived from indigo dye -bearing plants, primarily those in the genus Indigofera, which are native to the tropics. The primary commercial indigo species in Asia was true indigo ( Indigofera tinctoria ).

31 Chitimacha basket weavers have a complex formula for yellow that employs a dock plant (most likely rumex crispus ) for yellow. 42 navajo plan artists create yellow dyes from small snake-weed, brown onion skins, and rubber plant ( Parthenium incanum ). Rabbitbush ( Chrysothamnus ) and rose hips produce pale, yellow-cream colored dyes. 37 Greens edit If plants that yield yellow dyes are common, plants that yield green dyes are rare. Both woad and indigo have been used since ancient times in combination with yellow dyes to produce shades of green. Medieval and Early modern England was especially known for its green dyes. The dyers of Lincoln, a great cloth town in the high Middle Ages, produced the lincoln green cloth associated with Robin hood by dyeing wool with woad and then overdyeing it yellow with weld or dyer's greenweed ( Genista tinctoria also known as dyer's broom. 43 woolen cloth mordanted with alum and dyed yellow with dyer's greenweed was overdyed with woad and, later, indigo, to produce the once-famous Kendal green.

33 A delicate rose color in navajo rugs comes from fermented prickly pear cactus fruit, Opuntia polyacantha. 34 navajo weavers also use rainwater and red dirt to create salmon-pink dyes. 35 Oranges edit dyes that create reds and yellows can also yield oranges. Navajo dyers create orange dyes from one-seeded juniper, juniperus monosperma, navajo tea, thelesperma gracile, 36 or alder bark. 37 Yellows edit yellow dyes are "about as numerous as red ones 38 and can be extracted from saffron, pomegranate rind, turmeric, safflower, onionskins, and a number of weedy flowering plants. 38 39 Limited evidence suggests the use of weld ( Reseda luteola also called mignonette or dyer's rocket 40 before the Iron Age, 38 but it was an important dye of the ancient Mediterranean and Europe and is indigenous to England. 41 Two brilliant yellow dyes of commercial importance in Europe from the 18th century are derived from trees of the Americas : quercitron from the inner bark of Eastern Black oak ( quercus velutina native to eastern North America and fustic from the dyer's mulberry. 39 In rivercane basketweaving among southeastern woodlands tribes in the Americas, butternut ( Juglans cinerea ) and yellow root ( Xanthorhiza simplicissima ) provide a rich yellow color.

25 Madder and related plants of the genus Rubia are native to many temperate zones around the world, and were already used as sources of good red dye, such as rose madder, in prehistory. Madder has been identified on linen in the tomb of Tutankhamun, 25 and Pliny the Elder records madder growing near Rome. 26 Madder was a dye of commercial importance in Europe, being cultivated in the netherlands and France to dye the red coats of military uniforms until the market collapsed following the development of synthetic alizarin dye in 1869. Madder was also used to dye the "hunting pinks" of Great Britain. 26 Turkey red was a strong, very fast red dye for cotton obtained from madder root via a complicated multistep process involving " sumac and oak galls, calf's blood, sheep's dung, oil, soda, alum, and a solution of tin". 27 Turkey red was developed in India and spread to turkey. Greek workers familiar with the methods of its production were brought to France in 1747, and Dutch and English spies soon discovered the secret.

A sanitized version of Turkey red was being produced in Manchester by 1784, and roller-printed dress cottons with a turkey red ground were fashionable in England by the 1820s. 28 29 Munjeet or Indian madder ( Rubia cordifolia ) is native to the himalayas and other mountains of Asia and Japan. Munjeet was an important dye for the Asian cotton industry and is still used by craft dyers in Nepal. 30 Puccoon or bloodroot ( Sanguinaria canadensis ) is a popular red dye among southeastern Native american basketweavers. 31 Choctaw basketweavers additionally use sumac for red dye. 32 coushattas artists from Texas and louisiana used the water oak ( quercus nigra.) to produce the red.

13 Salt helps to "fix" or increase "fastness" of colors, vinegar improves reds and purples, and the ammonia in stale urine assists in the fermentation of indigo dyes. 13 Natural alum (aluminum sulfate) is the most common metallic salt mordant, but tin ( stannous chloride copper ( cupric sulfate iron ( ferrous sulfate, called copperas ) and chrome ( potassium dichromate ) are also used. Iron mordants "sadden" colors, while tin and chrome mordants brighten colors. The iron mordants contribute to fabric deterioration, referred to as "dye rot". Additional chemicals or alterants may be applied after dying to further alter or reinforce the colors. A dye-works with baskets of dyestuffs, skeins of dyed yarn, and heated vats for dyeing.

Using natural dyes to color the yarn of Tasar silk. Textiles may be dyed as raw fibre ( dyed in the fleece or dyed in the wool as spun yarn ( dyed in the hank or yarn-dyed or after weaving ( piece-dyed ). 19 Mordants often leave residue in wool fibre that makes it difficult to spin, so wool was generally dyed after spinning, as yarn or woven cloth. Indigo, however, requires no mordant, and cloth manufacturers in medieval England often dyed wool in the fleece with the indigo-bearing plant woad and then dyed the cloth again after weaving to produce deep blues, browns, reds, purples, blacks, and tawnies. 20 21 In China, japan, India, pakistan, nigeria, gambia, and other parts of West Africa and southeast Asia, patterned silk and cotton fabrics were produced using resist dyeing techniques in which the cloth is printed or stenciled with starch or wax, or tied in various. The Chinese ladao process is dated to the 10th century; other traditional techniques include tie-dye, batik, rōketsuzome, katazome, bandhani and leheria. 22 The mordants used in dyeing and many dyestuffs themselves give off strong and unpleasant odors, and the actual process of dyeing requires a good supply of fresh water, storage areas for bulky plant materials, vats which can be kept heated (often for days. Ancient large-scale dye-works tended to be located on the outskirts of populated areas, on windy promontories. 23 Common dyestuffs edit reds and pinks edit a variety of plants produce red dyes, including avocado pits, 24, a number of lichens, henna, alkanet or dyer's bugloss ( Alkanna tinctoria asafoetida and dyer's madder Rubia tinctorum.

12 Some dyestuffs, such as indigo and lichens, will give good color when used alone; these dyes are called direct dyes or substantive dyes. The majority of plant dyes, however, also require the use of a mordant, a chemical used to "fix" the color in the textile fibres. These dyes are called adjective dyes. By using different mordants, dyers can often obtain a variety of colors and shades from the same dye. Fibres or cloth may be pretreated with mordants, or the mordant may be incorporated in the dyebath. In traditional dyeing, the common mordants are vinegar, tannin from oak bark, sumac or oak galls, ammonia from stale urine, and wood-ash liquor or potash ( potassium carbonate ) made by leaching parts wood word ashes and evaporating the solution. We shall never know by what chances primitive man discovered that salt, vinegar from fermenting fruit, natural alum, and stale urine helped to fix and enhance the colours of his yarns, but for many centuries these four substances were used as mordants.

6 Textiles with a "red-brown warp and an ochre-yellow weft " were discovered in Egyptian pyramids of the sixth Dynasty (23452180 bce). 7 The chemical analysis that would definitively identify the dyes used in ancient textiles has rarely been conducted, and even when a dye such as indigo blue is detected it is impossible to determine which of several indigo-bearing plants was used. 8 nevertheless, based on the colors of surviving textile fragments and the evidence of actual dyestuffs found in archaeological sites, reds, blues, and yellows from plant sources were in common use by the late Bronze age and Iron Age. 9 In the 18th century jeremias Friedrich Gülich made substantial contributions to refining the dyeing process, 10 making particular progress on setting standards on dyeing sheep wool and many other textiles. 11 His contributions to refining the dying process and his theories on colour brought much praise by the well known poet and artist Johann Wolfgang von goethe. 10 Processes edit further information: Glossary of dyeing terms dyeing wool cloth, 1482, from British Library royal.E.iii,. The essential process of dyeing requires soaking the material containing the dye (the dyestuff ) in water, adding the textile to be dyed to the resulting solution (the dyebath and bringing the solution to a simmer for an extended period, often measured in days.

the health and environmental impact of synthetic dyes in manufacturing and there is a growing demand for products that use natural dyes. The european Union, for example, has encouraged Indonesian batik cloth producers to switch to natural dyes to improve their export market in Europe. 3 Contents dyes in use in the fashion industry edit oaxaca artisan Fidel Cruz lazo dying yarn for rug making Fibre content determines the type of dye required for a fabric: Cellulose fibres: cotton, linen, hemp, ramie, bamboo, rayon Protein fibres: wool, angora, mohair, cashmere. Protein fibres require vat, acid, or indirect/mordant dyes, that require a bonding agent. Each synthetic fibre requires its own dyeing method, for example, nylon requires acid, disperse and pigment dyes, rayon acetate requires disperse dyes, and. The types of natural dyes currently in use by the global fashion industry include: 4 Animal-derived dyes edit Plant-derived dyes edit Origins edit colors in the "ruddy" range of reds, browns, and oranges are the first attested colors in a number of ancient textile sites. The earliest surviving evidence of textile dyeing was found at the large neolithic settlement at Çatalhöyük in southern Anatolia, where traces of red dyes, possible from ochre ( iron oxide pigments from clay were found. 6 Polychrome or multicolored fabrics seem to have been developed in the 3rd or 2nd millennium bce.

Many natural dyes require the use of chemicals called mordants to bind the dye to the textile fibres; tannin from oak galls, salt, natural alum, vinegar, and online ammonia from stale urine were used by early dyers. Many mordants, and some dyes themselves, produce strong odors, and large-scale dyeworks were often isolated in their own districts. Throughout history, people have dyed their textiles using common, locally available materials, but scarce dyestuffs that produced brilliant and permanent colors such as the natural invertebrate dyes, tyrian purple and crimson kermes, became highly prized luxury items in the ancient and medieval world. Plant-based dyes such as woad ( Isatis tinctoria indigo, saffron, and madder were raised commercially and were important trade goods in the economies of Asia and Europe. Across Asia and Africa, patterned fabrics were produced using resist dyeing techniques to control the absorption of color in piece-dyed cloth. Dyes such as cochineal and logwood ( haematoxylum campechianum ) were brought to europe by the Spanish treasure fleets, and the dyestuffs of Europe were carried by colonists to America. The discovery of man-made synthetic dyes in the mid-19th century triggered a long decline in the large-scale market for natural dyes. Synthetic dyes, which could be produced in large quantities, quickly superseded natural dyes for the commercial textile production enabled by the industrial revolution, and unlike natural dyes, were suitable for the synthetic fibres that followed. Artists of the Arts and Crafts movement preferred the pure shades and subtle variability of natural dyes, which mellow with age but preserve their true colors, unlike early synthetic dyes, 1 and helped ensure that the old European techniques for dyeing and printing with natural.

Naturally dyed skeins made with madder root, colonial Williamsburg, va, 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 —and other biological sources such as fungi and lichens. Archaeologists have found evidence of textile dyeing dating back to the, neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years. The essential process of dyeing changed little over time. Typically, the dye material is put in a pot of water and then the textiles to be dyed are added to the pot, which is heated and stirred until the color is transferred. Textile fibre may be dyed before spinning dyed in the wool but most thesis textiles are " yarn -dyed" or "piece-dyed" after weaving.
