G&S Dye - Acid Dyes Jacquard Acid Dyes are fully certified and conform to ASTM D4236-86. Some dye colours are more dense than others, so use 1/2 jar for one pound of fabric, 1/3 jar for 1/2 lb of fabric, etc... Acid dyes are quite forgiving and amenable to variations in procedure. www.gsdye.com /Canada/acid_dyes.html   (629 words)

Dye - Wikipedia, the free encyclopedia The dye is usually used as an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dyebaths. Acid dyes are not substantive to cellulosic fibers. en.wikipedia.org /wiki/Dyes   (987 words)

The Effects of Acid Dye on Hand-Felted Wool Samples   (Site not responding. Last check: 2007-10-11) Make sure that each sample is covered with the acid dye solution for the duration of the experiment, as the wool tends to float at the top of the solution (see Figure 5). Sample 2: The magenta shade of the acid dye bath has lightened a little bit, suggesting that the wool sample is accepting the dye. At 40 minutes, none of the 3 samples have completely exhausted the acid dye baths, however the samples are all removed from the baths. www.sewanee.edu /chem/Chem&Art/Detail_Pages/Projects_2004/Sanders   (2299 words)

Olympus MIC-D: Polarized Light Gallery - Picric Acid The first synthetic dye, picric acid, was prepared in 1771 by British chemist Peter Woulfe from the extraction of the natural plant pigment, indigo, treated with nitric acid. To chemists, picric acid is also known as 2,4,6-trinitrophenol, carbazotic acid, or picronitric acid and features 6 carbons, 3 hydrogens, 3 nitrogens, and 7 oxygen atoms per molecule arranged in a benzene ring system with covalent bonding. Apparently, picric acid is not known to occur in nature, because of its highly unstable and reactive nature. www.olympusmicro.com /micd/galleries/polarized/picricacid.html   (378 words)

Liquid-crystalline mixture containing an azulenesquaric acid dye - Patent 5071588 The azulenesquaric acid dye of the formula I and the preparation thereof are known per se and described for example in earlier European Patent Application EP-A-310,080 and earlier German Patent Applications P 38 16 068.4 and P 38 16 187.7. Owing to the unexpectedly high solubility of the azulenesquaric acid dyes in the liquid crystal composition and the good order parameter, the novel liquid-crystalline mixture is advantageously suitable for fabricating liquid crystal displays where thermowriting is effected by irradiation with a laser beam. To this end, 50 mg of the dye were stirred into 1 ml of liquid crystal of type ZLI from Merck at room temperature in the course of 1 week, and the saturated solution was then centrifuged to remove the residue. www.freepatentsonline.com /5071588.html   (1624 words)

Invitrogen - Molecular Probes - Section 8.4 - Nucleic Acid Detection and Quantitation in Electrophoretic Gels and ... SYBR Gold nucleic acid staining is compatible with both Northern and Southern blotting — the stain transfers with the DNA or RNA to the blot and is washed off during incubation in the prehybridization mix. Because the nucleic acid–bound SYBR Gold dye exhibits excitation maxima at both ~495 nm and ~300 nm (the emission maximum is ~537 nm) (Figure 8.72), it is compatible with a wide variety of instrumentation, ranging from UV epi- and transilluminators and blue-light transilluminators, to mercury-arc lamp and argon-ion laser–based gel scanners. Dyes for nucleic acid sequencing by electrophoresis are discussed in Section 8.2. probes.invitrogen.com /handbook/sections/0804.html   (5845 words)

knitty.com Acid dyes however are a lot friendlier, both to you and the environment. On another level, while acid dyes seem proportionally a bit more expensive than other types by weight, if you consider that they're extremely effective and don't require any extra chemicals, they're actually one of the cheapest ways to go. The important point is that you need to not only get the dye onto your fiber, but you need it to chemically bind, to actually become part of the fiber. knitty.com /ISSUEsummer03/FEATaciddye.html   (2333 words)

VASHURINA IRINA YU. The analysis of the experimental data and thermodynamic parameters of the adsorption of two acid dyes (different in their molecular structure and affinity) by wool has led to the conclusion that for the dyes with high affinity to the fiber, structure breaking effects caused by small salt additions are strongly dependent on temperature.

DIRECTIONS 1.HTML The random effects produced by dipping or tie dyeing can also be produced using a technique of applying a cold, thickened solution of dye to the yarn, and storing cold for 24 hours. When all dyes have been poured, place hank in an old towel and either wring or roll with a rolling pin along the length of the hank. Dissolve Drimarene-K in water (For strong colour use 1gr of dye to 20 ml water, and for pastel shade use 1gr of dye to 200 ml of water). www.dyeman.com /directions1.html   (2211 words)

Dyeing Wool Fleece or Felt The advantage of using cake dyes is they are more concentrated than regular food colors and the amount of wool it was possible to dye with one container of cake dye was well over a pound before the pot was exhausted. Dyeing fibre whether in fleece, carded sliver or combed tops form is easier because there is no agitation of the fibres during dyeing and thus very little clumping of fibres together. Prepare dye quantities according to dry weight of fibre to be dyed and depth of colour required. www.peak.org /~spark/dyeingfelt.html   (4370 words)

Acid Levelling Dye (Kiton type) Dyeing Instructions Acid Levelling dyes are recommended for all protein fibers such as wool and mohair, plus nylon and acid-dyeable acrylics (often used in wool blends). Acid dyes work on silk, but are not as washfast as they are on wool. Acid Dyes are among the safest types of dyes, in fact, the recent use of Koolaid for dyeing actually depends on the food grade types of acid dyes (which is why they work on wool). www.straw.com /sig/kiton.html   (3190 words)

Invitrogen - Molecular Probes - Section 8.1 - Nucleic Acid Stains These dyes are generally considered to be cell impermeant, although their use to stain reticulocytes permeabilized by 5% DMSO has been reported. SYBR dye conjugates of solid or semisolid matrices (such as microspheres, magnetic particles or various resins) may be useful for detection or affinity isolation of nucleic acids. At pH 5, the free dye exhibits UV excitation maxima at ~330 nm and ~390 nm, with dual emission at ~450 nm and ~600 nm (Figure 8.35). probes.invitrogen.com /handbook/sections/0801.html   (7142 words)

Which washfast acid dye colors are pure, rather than mixtures? Acid dyes are used on animal fibers such as wool, in addition to silk and nylon. Note that, in spite of the name, not all of these dyes are particularly washfast (see washfastness data on the lightfastness page); as a rule, you should wash fabrics dyed with these dyes in cool water only. The dyes in each brand of dye are selected for compatibility, within that brand, but dyes that are found in only one brand just might be incompatible with those found only in the other. www.pburch.net /dyeing/FAQ/pureWFAcolors.shtml   (695 words)

Dyes for Protein Fibers Acid dyes are the most popular dyes used on wool, and comprise a very wide range of different dyes. Unlike other fiber reactive dyes, they contain a masking group which protects the reactive portion of the dye from reacting with the water in which the dye is dissolved, so these dyes will stay good for quite a long time after being dissolved in water, and are customarily purchased as liquids. All purpose dyes can be used to dye protein fibers, because they include an acid dye in their mixture. www.pburch.net /dyeing/proteindyes.shtml   (740 words)
