  • Batik Workshop
    Batik Workshop Batik is one of the "resist" processes for making designs on fabric, like Tie Dye, Shibori, Serti technique, etc., using wax on fabric to prevent dye from penetrating the cloth. Wax is applied to fabric, followed by dye, perhaps in many successive layers in complex Batiks. Batik is especially unique because the wax will crackle during handling, either intentionally or not. On subsequent dye baths, the crackles in the wax fill in with darker colors. Batik can be done with many types of dye or fabric paints & waxes on cottons, silks and other natural fabrics, particularly the finer weaves for detail work. "Faux" batik employs types of water soluble resists that are easier to remove than wax (and safer to work with for children), but never quite achieve that beautiful crackling. In this example we will be using Dharma Pigment Dyes and Soy Wax, on cotton, but can be adapted to other fabrics or dyes. The basic principles remain the same. Introduction to Batik Batik masters employ a process of repeated waxing and tub dyeing to achieve the final result. This method requires mastery of color mixing and over dyeing, as each layer of dye is applied over the last, producing a mixed color. After many different applications, the background usually comes out dark brown, black, or gray. The waxed areas remain the lighter shades produced by each individual application and combinations thereof. The Tub Dye technique is described below in more detail. An easier method of batik, especially for beginners, is the Paint-on method. This method has fewer steps and allows for great variations of color and shade without having to master the complicated blending of successive layers of color.

The history of alum mineral processing was reviewed to emphasise on the heritage knowledge inherited by current trends in fashion technology and textile engineering. The review will also demonstrate the conservative environmental preservation nature of alum mineral as mordant. The need for modern evaluation of natural dyes and mordants will be highlighted. Keywords: Alum; Mordant; Industrial heritage Introduction the calcined mass the calcined shale was barrowed to a series Alum was known as one of the most imperative components of stone leaching pits nearby with typical dimensions of 9 x of textile industry before the introduction of chemical dyes in 4.5 x 1.5m. Fresh liquid was added to the leaching tanks and the process repeated for several weeks. The waste solids were alum quarrying and trade in several geographical areas [1]. In the 1850s. Its significance could be explored when studying the literature, interesting notes on alum as a mordant for textile liquor from leaching rose to 1.12, indicating 12 tons of dissolved dyeing of yarn, cloth and leather in North America, China, Libya, eventually dug out and discarded.

  • Staining Wood and Natural Materials Using PRO Washfast Water Based
    Staining Wood and Natural Materials using PRO WashFast Water-Based Dyes Please read directions carefully before starting. Many materials, whose surface is only slightly wettable, may be colored with water-based (water soluble) dyes resulting in colored surfaces that do not hide the grain of the wood or the character of the substrate. This process is also suitable for the coloration of feathers, retouching wool tapestries and wool or nylon carpeting. Basically anything that does not have the high wash fastness requirements of wearable clothing fabrics. Wet fastness is good. Always do test samples before working on a large project. For additional information visit our web site at www.prochemicalanddye.com. Wear rubber gloves, apron, or old clothes. Utensils used for dyeing should never be used for food preparation. Procedure: 1. Dissolve the PRO WashFast Acid dye by placing 1 tsp (2.5 gm) of the dye in a one cup (250 ml) Pyrex container. Add 1 or 2 tsp (5 or 10 ml) of boiling water to make a paste. Gradually add more boiling water with continuous stirring to the 2 cup (125 ml) mark. Set aside to cool. 2. When cooled to room temperature, fill to one cup (250 ml) mark with denatured grain alcohol or Isopropyl rubbing alcohol (90%). Store in re-sealable glass container. 3. Apply to surface of substrate with foam brush or immerse object into dye solution for several minutes. Air dry and repeat procedure as often as needed for deeper color allowing previous coat to dry thoroughly. 4. After thorough drying, wood and similar materials may be coated to seal in the color and give lasting protection to the wood itself.

  • Batik Wax Instructions
    Instructions Batik Wax Batik: A History Although its exact origin is uncertain, the earliest known batiks were discovered in Egyptian tombs dating back to the 4th century BCE. Wax-resist techniques were probably developed independently by disparate cultures throughout the ancient world. By the seventh century AD, patterning fabric using resists such as wax was a widespread practice throughout Asia and Africa and was perhaps most fully developed as an artform in Indonesia, where batik predates written records. By the thirteenth century, it became a highly respected art form and pastime for the women of Java and Bali, as recognizable motifs, patterns and colors became signifiers of one’s family and geographical area. Distinct styles and traditions proliferated and spread with the exchange of cultures through trade and exploration (see the “inland” and “coastal” batiks of Java, for instance — the two traditions couldn’t be more different). In the seventeenth century, as the world grew smaller, batik was introduced in Holland and other parts of Europe, where it became increasingly fashionable. Europeans and Americans traveling and living in the East encountered the ancient process and brought it back to their homelands — and spread it to colonies far away — where new traditions of batik branched out. Today, art schools across the United States and Europe offer batik courses as an essential part of their textile curricula.

Healdsburg, CA 95448 | www.jacquardproducts.com | 800.442.0455 Batik Instructions Preparing and designing your fabric All new fabrics must be washed with hot soapy water, rinsed and dried to remove factory-applied sizings which may inhibit color penetration.

It is only recently (the first artificial dye was invented in 1857) that the textile industry has turned to synthetic dyes. Today, many craftspeople are rediscovering the joy of achieving colour through the use of renewable, non-toxic, natural sources. Natural dyes are inviting and satisfying to use. Most are familiar substances that will spark creative ideas and widen your view of the world. Try experimenting. Colour can be coaxed from many different sources. Once the cloth or fibre is prepared for dyeing it will soak up the colour, yielding a range of results from deep jew- el-like tones to dusky heathers and pastels.

  • Watercolors, Facepaint, Tie-Dye, and More!
    Playing with Plant Pigments: Watercolors, Facepaint, Tie-Dye, and More! Have you ever cooked with beets to find that your fingertips and cutting board are stained a vibrant red? Or maybe your favorite white coffee mug has a brown tint to the inside? If so, you’ve already experienced a plant pigment! There are some simple but magical techniques you can use to harness the brilliant colors found in plants - including the very ones found in your fridge. These pigments are easy to source, a ton of fun to experiment with, and a great way to use up some less-than-fresh produce. They are also an excellent alternative to harsh chemical dyes. Materials - Richly-pigmented food like: beet skins (pink), avocado peels and pits (pale pink), onion skins (yellow-orange), purple cabbage leaves (purple-blue), spinach (green), black beans (blue, believe it or not!), turmeric (golden yellow) - Saucepan - Strainer or slotted spoon Directions 1. Gather your pigmented ingredients. You’ll want at least one chopped cup of each item to create a deeply-saturated dye. 2. Add the chopped ingredients to a saucepan, and cover with twice as much water as the fruit or vegetable. Place over medium heat, and simmer for one hour. You can have multiple pots simmering at the same time. 3. Keep in mind: if you plan to dye fabric, you’ll want to make sure you have enough dye for the fabric item to float freely while it picks up color. When in doubt, make more dye than you think you need (which means you’ll need to use more fruits and vegetables).

  • Dyeing of Polyamide Fibres
    Dyeing of Polyamide Fibres Polyamides • Nylon a Polyamide, it is a condensation polymers. The formation of a polyamide is same as the synthesis of a simple amide. One prominent difference is that both the amine and the acid monomer units each have two functional groups ‐ one on each side of the molecule. In this polymer, the repeating units are identical. • Nylon is made from 1,6‐diaminohexane and adipic acid by elimination of water molecules (‐H from the amine and ‐OH from acid as shown in red on the graphic). • A simple representation is ‐[A‐B‐A‐B‐A‐B]‐. Nylon 66 • Nylon 66, was discovered in 1931 by Wallace Cruthers at DuPont. It was the first fully synthetic fiber produced. It was introduced to women in nylon stockings in 1939 with huge success. During World War II, nylon production was used to make parachutes and other items needed by the military. • Nylon is very similar in structure to the protein polyamides in silk and wool as shown earlier, but is far stronger, more durable, more chemically inert, and cheaper to produce as compared to the natural fibers. Polyamide Fibres • It’s a Nylon fibre we generally know. • It consists of multiples of six carbon chains, in which half the end of carbon being converted to carbonyl and other half to imino nitrogen. • It is thermoplastic , is sensitive to heat and tension applied in various texturizing processes. • Total temperature‐tension history of yarn determines the degree of orientation in textured yarns. Dyeing of Polyamide Fibres • Acid, metal complexes, disperse reactive and disperse dyes are the important classes of dyes used in dyeing of nylon.

  • Troubleshooting H&E Stain
    Melinda M. Chow, MS, HT(ASCP)CM Memorial Sloan Kettering Cancer Center Basking Ridge, New Jersey Hematoxylin & Eosin staining is the most frequent routine stain in the Mohs Micrographic Surgery tissue preparation. It has stood the test of time as the standard stain for histologic examination of human tissues since it was independently introduced in 1865 and 1875, by Böhmer and Fischer respectively. Common problems, pitfalls and troubleshooting tips. H & E is the primary diagnostic technique for evaluation of morphology in the histopathology labs. One of the best nuclear stains. H & E provides easier identification of histological features than T-blue. It is easy and simple to use. Stains are inexpensive, yet reliable and informative. It is stable and durable stain, lasting years without fading Hematoxylin is a natural dye extracted from the heartwood of logwood trees which is indigenous in Central America, Caribbean and other tropical countries. It is misleading to call hematoxylin stain as it alone does not stain. It has to convert to hematein. Hematein is what we call hematoxylin. It is a basic dye and carries a (+) charge. Affinity for basic dye is called basophilic. Hematein Chromatin (+) charge (-) charge Mordant (Al+3,Fe+3,Chr+3) This complex is held by covalent bonds Hematein-mordant-chromatin complex Courtesy of Biotek Progressive vs regressive Progressive stains are: Gill’s (I-III), Mayer’s Regressive stains are Harris's, Delafield's, Ehrlich's Progressive method : tissue is stained and stopped Regressive method: tissue is overstained Eosin is a synthetic stain It is the counterstain and acts as an acid dye.

THE INFLUENCE OF MORDANT ON THE LIGHTFASTNESS OF YELLOW NATURAL DYES Patricia Cox Crews ABSTRACT—Wool specimens were premordanted with alum, chrome, copper, iron, or tin mordants and dyed with 18 yellow natural dyes. 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.
