    Proceeding Indonesian Textile Conference (International Conference) 3rd Edition Volume 1 2019 http://itc.stttekstil.ac.id ISSN : 2356-5047 Effect of Different Solvent on Tegeran (Cudrania javanensis) Wood Extract Dyeing Quality on Silk Batik Vivin Atika 1 ,Tin Kusuma Arta 1, Dwi Wiji Lestari 1, Agus Haerudin 1and Aprilia Fitriani 1 1 Balai Besar Kerajinan dan Batik - Kementerian Perindustrian * Correspondence: [email protected]; Tel.: - Abstract: Tegeran (Cudrania javanensis) wood has been used as natural yellow dyes source for batik that traditionally obtained from extraction process by boiling in some amount of water. Tegeran dyes gives deep yellow color in cotton and silk batik with good fastness properties, but rarely reported about its result quality using different type of solvents in extracting process. Therefore, we conducted this research to find out how much different type of solvent in extracting process giving influence on dyeing result quality of silk batik. In this research has been carried out Tegeran wood extraction using four different solvent such as alcohol 70%, aquadest, acid/acetic acid solution pH 2.5 and alkaline/sodium hydroxide solution pH 12. The extract then used to dye batiked silk fabric. Tegeran wood extract coloring result in silk batik giving range colour from yellow to deep cream. The color strength values obtained were batik fabric dyed with Tegeran wood extract from alcohol 70% solvent 0.49, acid 0.57, aquadest 1.15, and alkaline 1.78. From color difference testing results, we obtain value of batik fabric colored with tegeran wood extract from alcohol 70 % L*=79.34, a*=6.37, b*=53.51; aquadest L*=87.91, a*=-0.69, b*=34.53; alkaline L*=76.06, a*=9.41, b*=14.76; and acid L*=77.70, a*=8.21, b*=36.72.

  • Eosin Staining
    Science of H & E Andrew Lisowski, M.S., HTL (A.S.C.P.) 1 Hematoxylin and Eosin Staining “The desired end result of a tissue stained with hematoxylin and eosin is based upon what seems to be almost infinite factors. Pathologists have individual preferences for section thickness, intensities, and shades. The choice of which reagents to use must take into consideration: cost, method of staining, option of purchasing commercially-prepared or technician-prepared reagents, safety, administration policies, convenience, availability, quality, technical limitations, as well as personal preference.” Guidelines for Hematoxylin and Eosin Staining National Society for Histotechnology 2 Why Do We Stain? In order to deliver a medical diagnosis, tissues must be examined under a microscope. Once a tissue specimen has been processed by a histology lab and transferred onto a glass slide, it needs to be appropriately stained for microscopic evaluation. This is because unstained tissue lacks contrast: when viewed under the microscope, everything appears in uniform dull grey color. Unstained tissue H&E stained tissue 3 What Does "Staining" Do? . Contrasts different cells . Highlights particular features of interest . Illustrates different cell structures . Detects infiltrations or deposits in the tissue .

As its name suggests, H&E stain makes use of a combination of two dyes – hematoxylin and eosin. It is often termed as “routine staining” as it is the most common way of coloring otherwise transparent tissue specimen.

Alizarin Red-S dye is one such examples. In this work, sorptive removal of Alizarin Red-S from water was investigated using Citrullus lanatus peels, in batch mode on laboratory scale. It was observed that adsorption of dye on Citrullus lanatus peels increases with increasing contact time and temperature, but decreases with increasing pH. Isothermal modeling indicated that physio- sorption occurred more as compared to chemi-sorption during adsorption of Alizarin Red-S by Citrullus lanatus peels, with qm 79.60 mg g-1. Thermodynamic and kinetic investigations revealed that this process was favourable and endothermic in nature, following pseudo- second order kinetics. Key Words: Citrullus lanatus peels, Alizarin Red-S, Adsorption, Isothermal modeling, Kinetics. INTRODUCTION Textile industries use a variety of dyeing materials for developing different colour shades. A massive amount of these dyes is wasted during processing which goes into effluents and poses problems for mankind and environmental abiotic and biotic factors by creating water pollution.

The Many Shades of Cochineal Red Workshop Review and Recap Tal Landeau Workshop Scholarship Recipient Michel Garcia’s workshop The Many Shades of Cochineal Red at the in Arlington Arts Center in Arlington, Virginia, was packed with multiple steaming pots, a couple of blown fuses and multiple vibrant hues of red, purples and oranges. Garcia demonstrated how the selection of mordanting processes used in conjunction with cochineal dye resulted in different nuances of the color red in the final dyed cloth and yarn. As a bonus and demonstration of other reds from natural dyes, Garcia also used madder to dye more fiber. The three mordanting methods outlined by Garcia were what he called the classical method, the forgotten method and the unknown method. The classical method uses the mineral salt alum (aluminum sulfate) and cream of tartar to mordant the fiber.

The dyed specimens were then exposed to a xenon‐arc lamp for 5, 10, 20, 40, and 80 AATCC Fading Units. The color changes were evaluated instrumentally with a color difference meter and visually by trained observers. Color differences in CIE L*a*b* units, gray scale classifications, and lightfastness ratings were reported. Turmeric, fustic, and marigold dyes faded significantly more than any of the other yellow dyes. However, dyes applied with tin and alum mordants faded significantly more than dyes mordanted with chrome, copper, or iron.

  • EL Art Dyeing with Plants
    Dyeing with Plants Authors: Richard Merrill & Susan Barrett Merrill Subjects: Art, Science (chemistry), Language The primary colors are red, yellow and blue. The primary plant dyes that produce these colors are: 1. Red a. Madder, Rubia tinctorum i. Chemical source in the plant: alizarin, purpurin 2. Yellow a. Goldenrod (Solidago species) i. Chemical source in the plant: b. Onion Skins (Allium cepa) i. Chemical source in the plant: 3. Blue a. Indigo (Indigofera tinctoria) i. Chemical source in the plant: indigotin (not soluble in water) b. Woad (Isatis tinctoria) i. Chemical source in the plant: indigotin, but smaller amounts Most natural dyes need a chemical called a mordant to help them bind to the fibers. These are often poisonous metallic salts, such as copper sulfate and potassium dichromate. We avoid these substances because their toxicity makes them dangerous to work with. Color Mordant Dye material Red Alum, Cream of tartar Madder Root Yellow Alum Goldenrod Yellow NONE Onionskin (yellow and red) Blue Yeast, sugar, ammonia, lye Indigo, woad Madder root and indigo are harder to come by. Goldenrod is seasonal in July through September, depending on your location, and requires alum, an aluminum salt, as a mordant. Onionskins are available to us year-round. Do not use blues for classroom work because of the noxious chemicals (ammonia) and dangerous caustic materials (lye). Alum is also toxic, so it is not recommended for classroom use. But there is one safe, fun way to dye naturally – onion skins! Dyeing with Onion Skins Start preparing the class by asking them to save and bring in onion skins from home (the papery part from yellow onions).

  • Extraction and Application of Avocado Dyes on Eco- Friendly Fabrics Using Batik Technique
    Report of the Minor Research Project Sponsored by UGC Principle Investigator: Dr. S. KAUVERY BAI Project Fellow: Pavitra S Associate Professor, Department of Textiles and Clothing Smt. VHD Central Institute of Home Science, (Autonomous) Seshadri Road, Bengaluru Extraction and Application of Avocado Dyes on Eco- Friendly Fabrics Using Batik Technique. Introduction Colour Attracts and holds attention.....humans have been attracted to colour and have devised ways to add colour to all things, and this has evolved into a science long before chemical dyes were discovered. Natural dyes have been used in early cave paintings as the first form of documented expression or communication. Later these dyes were applied as tattoos; permanent and temporary before showing up on textiles. All the murals depicting textiles in painting found in the caves at Ajanta and Ellora as well as the various paintings documenting the past, show coloured garments. A wide variety of natural materials were used in combination to get different colours, not only were these dyes, ‘clean colours’ but also were bright and fast when used on all kinds of natural fabrics. India is a country famous for its textiles especially dyed, printed, embroidered and intricately woven fabrics. When studying Natural dyes, it is seen that certain colours were automatically considered those of the privileged class, as they were available only at a high cost since the natural sources itself were found in limited quantities, e.g. Tyrian purple. Natural dyes are colours obtained from plant, animal or mineral sources. These natural matters are made to undergo various processes to extract colour from them.
