Interestingly a Javanese botanical survey of natural dye plants in the Melolo region of East Sumba identified the species used for making the yellow dye as Maclura cochinchinensis and not Maclura spinosa. Flavanones have the flavone backbone without the double bond in the central ring. Local dyers tell us that they prepare the dye from turmeric, morinda root and lime. Curcuminoid solutions show strong light absorption in the ultraviolet to light-blue parts of the spectrum (300 to 500nm), making them appear yellow to orange. Naphthol yellow S Naphthol yellow S Sulfur yellow S, Acid yellow S 10316 Acid yellow 1 Nitro Acid 8% Slightly 428, 392 (Conn) 427, 390 (Gurr) Yellow C 10 H 4 N 2 O 8 SNa 2 358.2 (Aldrich, Merck), 412.254 (Conn) This dye has been recommended by Shoobridge for use as a staining "primer" in his polychrome method. In traditional Indian calico-dyeing turmeric was often applied last by hand, especially over indigo, to colour in details such as leaves (Peck and Bogansky 2013, 131). Dyers prefer to use a mixture of kayu kuning, lime (kapur) and turmeric. It produces pyramidal inflorescences of pinkish-white pink flowers, which mature into clusters of fruit. Jackfruit occurs throughout the Indonesian archipelago, from Sumatra to Tanimbar, Maluku and Papua. Natural Dyeing Processes of India, Calico Museum, Ahmedabad. We presume it was not kayu kuning since that author was already well aware that Cudriana was a widely used source of colourfast yellow in Indonesia (Barnes 1989, 15). Throughout most of the early historical period, wild mignonette - known as weld or dyer’s rocket (Reseda luteola) - seems to have been the most common yellow dye used in Western Europe (Liles 1990, 33). Adams noted that ‘curcuma wood’ was sometimes used for dyeing decorative yarns used in lau or the kabakil end bands of hinggis (Adams 1969, 182). The process is called chelation, meaning that it involves the formation of two or more chemical bonds. In practice the most important dye source is true turmeric, Curcuma longa, because it contains the highest concentration of curcuminoid pigments. Yellow was also obtained from the flowers of kam nong (safflower, Carthamus tinctorius); the seedpods of mak pin (the bael tree, Aegle marmelos); the wood of mai ma na (black myrobalan, Terminaria chebula); and the rhizomes of kamin or turmeric (Cheesman 1988, 59). Pigment Red 112, a newer Naphthol Red that possesses a very clean, yellow hue and that finds use in both industrial and architectural paints. The Encyclopaedia of Fruit and Nuts, Cambridge University Press. In Lampung the distinctive mustard yellow bands in the ceremonial tapis skirts were produced from a dye composed of turmeric, lime (kapur sirih) and tamarind (asam Jawa) (Totton 2009, 42). Fortunately flavonoids form complexes with a wide range of metal ions such as aluminium, copper, iron, chrome, and tin. He further instructing that the dye should always be boiled (Rhys-Davids and Oldenberg 2012). The resin is tapped from cuts spiralling down the trunks and is collected in bamboo canes. They include the yellow pigments morin (from. It was more widely used as a foodstuff, medicine and a body dye. When acidity is reduced to pH 8 or higher it becomes yellow, with a λmax at 420nm (in the blue) (Pilipenko et al 1972). Cockspur Thorn or Kayu Kuning It is produced by sulfonation of α-naphthol, with subsequent nitration of the product. Proto who utilised turmeric, and how? Aurones are the smallest group in the flavonoid family (Anderson and Jordheim 2010, 583). Jackfruit is included in an inventory of yellow dyes used in Shan State in the late nineteenth century along with the barks of tauksha (Vitrex glabrata), thingan (Hopea odorata), tayetngapyaung, taungthale (Garcinia cowa) and coconut, as well as the roots of nyaw (Morinda coreia, formerly M. exserta), the latter sometimes mixed with turmeric (Scott and Hardiman 1900, 382-383). On Flores it is specifically cultivated in Manggarai and Sikka, and probably in every other regency (Deardon, Neilson and Lansdowne 2002, 57; Metzner 1982, 127). After dyeing, the cloths were washed in the river to leave them a dull-yellow colour, meant to symbolise greatness and fame (Cederroth 1995, 34 and 42). In some parts of Indonesia turmeric-dyed threads were rinsed in citrus or tamarind juice to improve colour fastness (Warming and Gaworski 1981, 71). These relatively small molecules are of only low to moderate substantivity for cotton, but they diffuse rapidly into the fibres. They belong to the mulberry or Moraceae family, which also includes jackfruit (Artocarpus heterophyllus) and breadfruit (Artocarpus altilis). M'Cann, Hugh W., 1883. Although yellow is achieved without the use of a mordant, mordants can be added to modify the colour and to improve light-fastness. It is primarily used for textile dyeing. The red returned when the solution was neutralised with citric or tartaric acid, just before the yarns were immersed in the bath (O’Neil and Fesquet 1869, 399-401). For solubilising of naphthols and keeping proper alkalinity of naphthol bath. The safflower is a warm temperature crop, originally endemic to Western Asia. On Lombok the Sasak used turmeric to dye the stripes in their sacred, coarsely woven white cotton umbaq kombong cloths, given to every young child and subsequently used at ceremonies celebrating important life-cycle events. Flavones have a double bond in the central heterocyclic ring. The climber grew in forested areas, but was generally considered uncommon in East Sumba. The sap of rong (claimed to be the mangosteen, Garcinia mangostana) was used as a yellow dye in Thailand (Conway 2002, 181). See Soga under Brown Dyes. Naphthol dyes offered by us are insoluble Azo dyestuffs that are produced on fiber through application of Naphthol to fiber and then combining it with diazotized base at low temperatures. Naphthol yellow (II) is used in a number of countries as a food dye. In Laos Patricia Cheesman claims that yellow and orange were obtained from the leaves of either bai keua, bai kae or kam med, respectively Cudriana cambodiana, now Maclura cochinchinensis or cockspur thorn, Cudriana poianea and the rosewood Dalbergia stipulacea (Cheesman 1988, 59). Yellow is mainly used for dyeing the narrow plain warp stripes in the end sections of women's èi or the side bands of men's hi’i  - locally known as the wurumada or 'delicate eyes'. The yarn was dyed in this solution four times over a period of four days (Nabholtz-Kartaschoff 1991, 128). Crocking fastness varies with shades but washing fastnessis equal to Vat dyeings, generally with less light fastness than the Vats. Dissolution of base and to produce nitrous acid in diazotization phase. The sapwood or heartwood of jackfruit produces a relatively stable orange-yellow dye, extracted by boiling wood chips or sawdust in water. Laban Bark Sometimes these ingredients were mixed into a cocktail. To date we can find no indication that it was used as a dye source in Indonesia.

( Log Out /  The province of Ligor, in Southern Thailand, was an important producer of cockspur thorn, known locally as kleh. Max Weber collected the recipe in 1972: one kilogramme of turmeric, one small lime fruit and one pineapple leaf were powdered, added to five times as much water, stirred and sifted. Jackfruit wood has a pH of 11 and contains at least 40 different flavonoids, including the yellow colorants morin and artocarpin (Leela 2012, 90-93). In Thailand the tree is known as maj prahoot and the dye is prepared by boiling the wood chips in water. cool to 85 degC. Chemically the flavonoids can be subdivided into flavones, flavonols, isoflavones, flavanones, chalcones, and aurones, the latter named after aurum, the Latin for gold (Freeman and Peters 2000, 431). Faridah Hanum, I.; and Van der Maesen, L. J. G., (eds), 1997. In northern Thailand yellow was obtained from the leaves of makham thai (tamarind, Tamarindus indica); the sap of rong (mangosteen, Garcinia mangostana); the heartwoods of jackfruit (Artocarpus integrifola) and kae lae (cockspur thorn, Cudriana javanensis); the seedpods of ma tum (the bael tree, Aegle marmelos); the bark of nom meo (Rauwenhoffia siamensis); the flowers of night jasmine (Nyctanthes arbor-tristis); and the root of khamin chan or turmeric (Conway 2002, 181). Mango leaf has been found to include a mixture of galloyl and hydroxybenzoyl esters as well as epicatechin. In India they used a multitude of yellow dyes, far too long to mention, with different dyeing recipes used in different regions (Mohanty, Chandramouli and Naik 1987, 21-25). It belongs to the family Asteraceae. Flavonols have a hydroxyl group at carbon-3, between the ketone and the outer ring. Dyers at Nita Kloang in the Krowé region also mix turmeric with mango bark. In Cambodia annatto was used to produce a dark yellow colour for silk. Post-mordanting with alum and iron has been shown to produce maximum colour strength and dark yellow shades (Adeel, Bhatti, Kausar and Osman 2012, 89). Isoflavones differ from flavones because the location of the outer aromatic ring (on the right) migrates from carbon-2 to carbon-3 (Preedy 2012, 17). It is more likely that dyers used the wood and bark of these trees, not their leaves. The main varieties harvested are Garcinia hanburyi, which grows in Cambodia and Thailand and produces Siam gamboge; G. morella and G. cambogia, which grow in India and Sri Lanka and produce Ceylon gamboge; and G. elliptica and G. heterandra, which are found in Burma (Eastaugh, Walsh, Chaplin and Sidall 2008, 170-171; Yaacob and Tindall 1995, 15). The Yellow Curcuminoid Dyes Of great concern to museums, one study found that yellow natural dyes would be completely destroyed after fifty years of permanent exhibition in even the dimmest tolerable conditions (Padfield and Landi 1966, 191). These curcuminoids are direct (substantive) dyes that do not require a mordant. Both probably originated in India and Malaysia (Janick and Paull 2008, 481). Address: Shandong province Jining City Wenshang County Association of Chemical Industry Park. Because the basic flavonoid chromophore is susceptible to photochemical attack all flavonoids are degraded by photo oxidation, which decomposes them into quinines and other simpler components. They occur in bacteria, algae, leaves, flowers, fruits, and roots and are named after β-carotene, which was isolated from carrots by Wackenroder in 1831 (Cooper and Nicola 2014, 125). They embrace a huge variety of chemical structures and can be divided into carotenes, hydrocarbons containing only carbon and hydrogen, and xanthophylls (from the Greek xanthos for yellow and phyllon for leaf), made up of carbon, hydrogen and oxygen. The majority of East Sumba textiles do not include yellow. Another found that cotton dyed with turmeric without a mordant had good saturation and rubbing fastness but poor washing and light fastness. Of these, turmeric gives the strongest yellow but is the least lightfast and wash-fast. Application of Purified Curcumin as Natural Dye on Cotton and Polyester, International Journal of Engineering & Technology, vol. In Cambodia prahout (G. vilersiana) grows in the highlands. Colour Index Number 10316 . To make the red dye the yellow pigment was first removed and discarded by rinsing the safflower petals in water until it ran clear. Mangiferin has been found to be the predominant component (10%) of mango bark extract (Masebo and He 2008). By the 1800s thousands of tons a year were being shipped to Europe and the USA under the name of dyer’s mulberry or old fustic, primarily for the dyeing of wool and much later khaki (Keeler 2014). One Kambera producer adds tea to the kayu kuning to make a golden yellow. In Soekanegara, West Java, the leaves were mordanted with copper sulphate to produce green (Jasper and Pirngadie 1912, 66). A modification of the Deitch "standard" naphthol yellow S technique is described and validated for use in deoxyribonucleic acid and protein determinations in drosophila larval material. Consequently UV-Vis spectroscopy is a useful tool for their structural analysis. 88-99, PROTA Foundation, Wageningen. Naphthol Dyes & Salts Royce offers a full-line of Naphthol dyes, and Naphthol salts that when combined offer bright, high-fastness azoic colors for dyeing cotton fabrics. Linguists believe that the words for turmeric (kunij), jackfruit (nanka), breadfruit (kulur), and mango (wai) were all present in the Proto-Malayo-Polynesian lexicon (Blust 1988, 61). Many species are also found in Burma and Thailand (Prabhakaran Nair 2013, 7). 2-Naphthol has a slight odor. naphthol yellow, aluminum salt (3:2) "What do you need help with?" In general, the higher the substantivity the better the rubbing fastness as less azo pigment forms on the fibre surfaces. Safflower was certainly used on Bali in the distant past and was still being cultivated in the mountain regions up to the nineteenth century (Stuart-Fox 1993, 89). 4.Use of excess salt in naphthol bath may result into precipitation of the bath. Its early spread may have been related to the Hindu religion. Naphthol AS-E,Azoic dyes AS-E. Shandong Andy new materials Co., Ltd. provides you with the best cost performance products and services. Safflower was also used as an alternative to turmeric at Lamalera on Lembata to give a yellow with similar poor fastness (Barnes 1989, 15). Today jackfruit is only used in the Lesser Sunda Islands by a few groups, such as the Sikka of 'Iwang Geté region and the Amarasi of Baun in West Timor. Osage orange (Maclura pomifera), a second American species, was used by native Indians in the south-central USA to produce a yellow-orange dye (Vijayan, Tikader et al 2011, 87; Austin 2004, 424). It is a substantive (direct) dye that can dye cotton without the use of a mordant, producing a vivid and deep yellow-orange. Although it was once thought that the Mangifera originated in India before spreading into Southeast Asia, it is now accepted that its centre of origin lay in Southeast Asia (Mukherjee and Litz 2009, 8). For example, in the Chittagong Hills of Burma yellow was extracted from the roots of various unnamed trees and shrubs (Barbe 1845, 386). Naphthol yellow S is an organic compound that is a dye. For example, the addition of an aluminium mordant produces a more intense yellow, while alkali turns it into a dark yellow approaching orange. Safety.

Riedel claimed that on Leti the local ‘frizzy haired’ natives obtained yellow by cooking the the bark of the unspecified amiare [tree?] Mango bark contains various phenolic acids, phenolic esters and the two flavan-3-ols, catechin and epicatechin. This is one of the reasons why many old textiles appear predominantly brown – they have lost the vitality of their youth. XX, issue X, pp. Recrystallize the crude sample by dissolving in carbon tetrachloride to get the pure dye. It is especially common in Malaysia, Sumatra, Kalimantan and Sulawesi, but is also found throughout the Lesser Sunda Islands. The most important are bixin and its water soluble form norbixin, obtained from annatto, and crocin, obtained from saffron, harsinghar, and Indian mahogany. Because of its quality and deep yellow colour, jackfruit timber was often the preferred choice for royal palaces in Bali and Makassar (Sulawesi) and for temples in Vietnam (Tate 2000). The tree grows in equatorial to subtropical maritime climates in lowland rain forest with an average rainfall of 100 to 240 cm. It is cultivated throughout Nusa Tenggara Timur (Pellikila et al 1991). It is a derivative of 1-naphthol. Dyeing of Textiles with Natural Dyes, in Natural Dyes, InTech, Rijeka. Turmeric is thought to have originated in southern Asia as wild turmeric (Curcuma aromatica), probably the Indo-Malaysia region where it was domesticated and interbred with other Curcuma species (Jansen and Cardon 2005, 68). It was also shipped in the form of cake or lump gamboge and coarse gamboge (Christison 1836, 233-2). Alternatively the tubers can be washed, peeled and dried and then ground into a powder for future use (Fraser-Lu 1989, 30). In response, the Buddha prescribed six generic types of natural dye that could be used instead, namely: roots, tree trunks, barks, leaves, flowers and fruits. However yellow flowers contain little red pigment. In addition to C. longa, six other species have been found to contain curcuminoid colouring agents (Aggarwal et al 2007, 4). Interestingly the fruit hulls of mangosteen (G. mangostana) are used to make a red dye for cotton and silk by villagers in Nakhon Si Thammarat, southern Thailand (Chairat, Bremner and Chantrapromma 2007). Consequently flavonoid yellows turn dull brown over time (Crews 1982). In chapter 29 the Buddha forbade monks to wear robes that were coloured light yellow, brownish-yellow, dark yellow, blue, crimson or black. Laban produces a very hard wood that is ideal for construction and for making charcoal, and gives the tree considerable fire resistance. For the chemistry of morin see Kayu Kuning below. They are both xanthophylls. It is not volatile and will dissolve moderately in water. "The Chemistry of Hat Manufacturing" by Watson Smith Naphthol Yellow S… Its branches are armed with viscous auxiliary spines up to 2cm long, which are either straight or curved. Medical dictionary. Its heartwood was used to produce a bright yellow dye tinged with orange that was known as old fustic or dyer’s mulberry. In the past its use as a yellow dye was avoided by European dye houses. 5.Development or treatment with the diazonium ion solution to bring about coupling. In the Indonesian archipelago yellow dyes were not so varied, but still differed by region. The Yellow Carotenoid Dyes We have found limited evidence that it has been used in the past as a very minor dye in India, Thailand, Laos, Cambodia, Vietnam, Sarawak and the Philippines and possibly also in Burma. Several immersions were required to produce the right shade (Barnes 1989, 31). Depending on the dyeing conditions, jackfruit wood can produce a wide variety of colours, ranging from muddy yellow, to golden and orange yellow, through to apricot and tan (Fraser-Lu 1988, 30).

A crystalline solid derived from naphthalene, used to make antiseptics and dyes. PROTA: Plant Resources of Tropical Africa 3: Dyes and Tannins, pp. The latter authors apply linguistic gymnastics to conclude that the word initially referred to both the colour yellow and to yellow dye. However to become an effective dye the flavonoid is best combined with a metallic mordant to form one or several flavonoid metal complexes. Turmeric's lack of light-fastness is less of a problem for adat cloths that are rarely exposed to light. It was later spread into Europe by Arab traders (Prabhakaran Nair 2013, 2). It is used to dye silk. Examples include yellow genistein, pale yellow daidzein, pale yellow luteone and off-white to yellow puerarin. Clark, Mathew, 2011.

An analysis of dried safflower flowers in China found that they contained 30% of the yellow pigment but only 2% of the red (Smith 1996, 50). Its disadvantage is that it is the least lightfast of all ofthe yellow dyes, fading faster by a factor of four. Because of this, curcuminoid dyes can only be effectively used in either neutral or acidic conditions, within which they remain virtually insoluble. Most artisan dyers use a weakly acidified turmeric dye bath without the addition of heat or a metal mordant. Naphthol dyes are classified as fast dyes and available at very competitive prices. Plants as the Pivot: the Ethnobotany of Timorese Textiles, in Textiles of Timor, Fowler Museum, LA. 5.The temperature is very important in base preparation stem , otherwise diazotization may not take place. Growth is moderately rapid in the early years, up to 1.5 m in height per year, but slows as the tree reaches maturity. Its main weakness as a cotton dye is that being sensitive to visible and near UV light it is very fugitive and quickly fades in sunlight, even when applied with a mordant (Bowman and Reagan 1983). The active ingredient of mango dye is mangiferin, a xanthone C-glycoside.
