S. School, Agartala, Tripura, India. 4 Department of Human Physiology, Swami Vivekananda Mahavidyalaya, Mohanpur, Tripura, India. *Corresponding author: Biplab De, E-mail: [email protected] Received: February 20, 2017, Accepted: April 15, 2017, Published: April 15, 2017. ABSTRACT: The majority of natural colourants are of vegetable origin from plant sources –roots, berries, barks, leaves, wood and other organic sources such as fungi and lichens. In the medicinal and food products apart from active constituents there are several other ingredients present which are used for either ethical or technical reasons. Colouring agent is one of them, known as excipients. The discovery of man-made synthetic dye in the mid-19th century triggered a long decline in the large-scale market for natural dyes as practiced by the villagers and tribes. The continuous use of synthetic colours in textile and food industry has been found to be detrimental to human health, also leading to environmental degradation. Biocolours are extracted by the villagers and certain tribes from natural herbs, plants as leaves, fruits (rind or seeds), flowers (petals, stamens), bark or roots, minerals such as prussian blue, red ochre & ultramarine blue and are also of insect origin such as lac, cochineal and kermes. -

Tutorial: How to Dye Black with Natural
http://www.aurorasilk.com/ Tutorial: How To Dye Black with Natural Dyes by Cheryl Kolander. Excerpted from TrueFibers. Aurora Silk sells a full selection of natural dyes and mordants. For ideas on which dyes and which mordants to use, view our Natural Dye colour Chart. For more detailed dyeing recipes, read Brilliant Colours! by Cheryl Kolander. After recording the dry weight of your fiber, wet the fiber out in warm or hot water. STEP I: TANNIN 2 oz. tannic acid per pound of fiber (dry weight) OR: 4 oz. tara sawdust per pound of fiber, extracted twice OR: 3 oz Catechu (Cutch) extract per pound of fiber with optional 1/2 oz copper mordant 1. Dissolve tannic acid or catechu extract in hot water. 2. Heat the solution to approximately 200 F. 3. Remove from heat. 4. Enter the silk (or other fiber) that has been thoroughly wet out in warm to hot water. 5. Set to soak for at least 24 hrs, stirring occasionally. STEP II: IRON 1/2 to 1 oz Ferrous Sulphate per pound of fiber Use the lesser amount for fine silk yarn and soft wools. Use the greater amount for wild silk and other fibers. 1. Dissolve the iron in warm water. 2. Soak fiber in a mild soap solution about 15 minutes to neutralize the acid in the tannin (which couters the effect of the iron). This step is not necessary if you used Catechu for STEP I. 3. Add fiber to warm iron solution and soak for about 20 minutes. 4. Remove fiber from iron solution, wring excess solution from fiber, and hang to air 20 minutes to 1 hour. -

Made up mainly of limestone and sedimentary rocks, Sumba’s topography con - sists of numerous hills and a plateau covered with grassy savannah interspersed with valleys hollowed out by erosion where gallery forests grow. The climate is hot and arid, except during the rainy season that lasts from December to March. With fewer than 600,000 inhabitants, Sumba boasts one of the low - est population densities in Indonesia. The island is divided into two administrative districts, West and East Sumba; the east has greater ethnic, cultural, and linguistic unity than the western part. 2 The town of Waingapu is the administrative center of East Sumba; it is also its Fig. 1.

An Atlas of Rare & Familiar Colour THE HARVARD ART MUSEUMS’ FORBES PIGMENT COLLECTION Yoko Ono “If people want to make war they should make a colour war, and paint each others’ cities up in the night in pinks and greens.” Foreword p.6 Introduction p.12 Red p.28 Orange p.54 Yellow p.70 Green p.86 Blue p.108 Purple p.132 Brown p.150 Black p.162 White p.178 Metallic p.190 Appendix p.204 8 AN ATLAS OF RARE & FAMILIAR COLOUR FOREWORD 9 You can see Harvard University’s Forbes Pigment Collection from far below. It shimmers like an art display in its own right, facing in towards Foreword the glass central courtyard in Renzo Piano’s wonderful 2014 extension to the Harvard Art Museums. The collection seems, somehow, suspended within the sky. From the public galleries it is tantalising, almost intoxicating, to see the glass-fronted cases full of their bright bottles up there in the administra- tive area of the museum. The shelves are arranged mostly by hue; the blues are graded in ombre effect from deepest midnight to the fading in- digo of favourite jeans, with startling, pleasing juxtapositions of turquoise (flasks of lightest green malachite; summer sky-coloured copper carbon- ate and swimming pool verdigris) next to navy, next to something that was once blue and is now simply, chalk. A few feet along, the bright alizarin crimsons slake to brownish brazil wood upon one side, and blush to madder pink the other. This curious chromatic ordering makes the whole collection look like an installation exploring the very nature of painting. -
ABSTRACT YI, DING. a Comparison of Mordant and Natural Dyes In
ABSTRACT YI, DING. A Comparison of Mordant and Natural Dyes in Dyeing Cotton Fabrics. (Under the direction of Dr. Harold S. Freeman and Dr. Peter J. Hauser). Mordant dyes constitute a class of synthetic colorants that are applied to textile fibers mainly through the aid of transition metal ions such as Cr3+. The resultant dye-metal complexes are key to the fastness properties produced on wool. In the same way, most natural dyes require the use of a mordant to have coloring power on textiles such as cotton. Unlike mordant dyes on wool, the fastness properties of natural dyes on cotton are generally quite low. Consequently, they have largely been replaced by synthetic dyes that are more cost effective, brighter, and more durable under end-use applications. Interest in green technologies has led to renewed consideration of natural dyes for textile coloration because they are biodegradable and do not involve manufacturing processes requiring genotoxic aromatic amines. Interestingly, such a shift would bring dyeing technology full circle to a family of colorants lacking the vibrancy and technical properties of most synthetic dyes. However, similarities between the dyeing method for mordant and natural dyes brought to mind the potential for reducing the level of synthetic dyes used commercially by combining suitable dyes from these two classes for dyeing textiles. This thesis research was devoted to stage 1 of this idea, namely the evaluation of mordant dyes as colorants for cotton fabric. With this in mind, dyes such as Mordant Blue 13, Mordant Brown 40, Mordant Orange 6 and Mordant Yellow 8 were applied to cotton using various dyeing times, temperatures, dye bath concentrations and mordants. -
Remission of Duties & Taxes on Exported Products (Rodtep)Scheme

With reference press note dated 31.12.2020 issued by CBIC on the new RoDTEP scheme being operationalized from 01.01.2021. Necessary changes in the System have also been made to accept and process RoDTEP claims. SILENT FEATURES OF THE SCHEME: ❖ The Scheme will take effect for Exports from 1st January 2021. However, effective date for export obligation under advance authorisation, export by 100% Export Oriented Units (EOU), export by Special Economic Zone (SEZ), export by Free Trade Zone will be decided later. ❖ The rebate would be claimed as a percentage of the Freight on Board (FOB) value of exports with value cap per unit of the exported product. ❖ The Scheme will be implemented with end-to-end digitization. ❖ RoDTEP rates will be reviewed annually and will be notified well in advance before the beginning of the Financial year. ❖ The Scheme will operate in Budgetary framework of each financial year and necessary calibrations and revisions will be made as and when required so that the projected remissions for each financial are managed within the approved budget of the Scheme.
