Why is rubbing alcohol used during a chromatography where the goal was to separate different colored sharpies into their components? In this experiment, rubbing alcohol (isopropyl alcohol) is used as the solvent (mobile phase) for paper chromatography separation. The dyes (or pigments) of Sharpie marker can be dissolved in rubbing alcohol, and move along with the solvent as it travel up the stationary phase (the paper) due to capillary action.

- Properties of reactive dye: 1  Reactive dyes are anionic dyes, which are used for dyeing cellulose, protein and polyamide fibres. 2  Reactive dyes are found in power, liquid and print paste form. 3  During dyeing the reactive group of this dye forms covalent bond with fibre polymer and becomes an integral parts of the fibre.

How do you use Rit dye? Remove stains from fabric or use Rit Color Remover to get fabric to an off-white or cream color to help achieve uniform results when dyeing. In 2 cups of very hot water, dissolve the dye thoroughly to avoid dye spotting. Stir the dissolved powder or liquid dye into the bath until evenly dispersed. Use a water temperature of 140 degrees Fahrenheit for deepest color. If dyeing more than one color, starting with the lightest color usually works best. Adding 1 cup of salt to the dye bath when dying fabrics containing cotton, rayon, ramie or linen creates more intense color. For nylon, silk and wool, add 1 cup of white vinegar to achieve that effect.

Dye Acid dyes are not substantive to cellulosic fibers. Most synthetic food colors fall in this category. Basic dyes are water-soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Usually acetic acid is added to the dyebath to help the uptake of the dye onto the fiber.Basic dyes are also used in the coloration of paper.irect or substantive dyeing is normally carried out in a neutral or slightly alkaline dyebath, at or near boiling point, with the addition of either sodium chloride (NaCl) or sodium sulfate (Na 2 SO 4) or sodium carbonate (Na 2 CO 3). Direct dyes are used on cotton, paper, leather, wool, silk and nylon.

- Similar to faux finishing techniques, concrete dyes are applied in creative ways with sprayers, mops, sponges, rags, plastic sheets and other materials. As it's applied, the concrete is simultaneously stained and sealed. With concrete dye, it's difficult to achieve the depth of color that acid staining offers, but it's a fairly inexpensive process, and the ease of application can reduce labor costs. Concrete dye is also able to hide imperfections to some degree. A clear coat must be used on acrylic dyes to protect the color.

Dye 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 dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber. dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.
