Q: Is a dye a colored substance that has an affinity to the substrate to which it is being applied? ¶
A: Yes.
Q: Are dyes finely ground in the presence of a dispersing agent and sold as a paste? ¶
A: Yes, or spray-dried and sold as a powder.
Q: Are dyes water-soluble cationic dyes that are mainly applied to acrylic fibers? ¶
A: Yes, but find some use for wool and silk.
Q: Are dyes not substantive to cellulosic fibers? ¶
A: Yes.
Q: Were dyes originally developed for the dyeing of cellulose acetate? ¶
A: Yes, and are water-insoluble.
Q: Are dyes classed as food additives? ¶
A: Yes, and they are manufactured to a higher standard than some industrial dyes.
Q: Are dyes essentially insoluble in water and incapable of dyeing fibres directly? ¶
A: Yes.
Q: Are dyes made from petroleum? ¶
A: Yes, and sometimes in combination with mineral-derived components.
Q: Are dyes derived from plant sources: roots? ¶
A: Yes, and berries, bark, leaves, and wood, fungi, and lichens.
Q: Is a dye generally applied in an aqueous solution? ¶
A: Yes, and may require a mordant to improve the fastness of the dye on the fiber.
Q: Are dyes man-made? ¶
A: Yes.
Q: Are dyes the synthetic mordant dyes, or chrome dyes, used for wool? ¶
A: Yes, these comprise some 30% of dyes used for wool, and are especially useful for black and navy shades.
Q: Are dyes also used? ¶
A: Yes.
Q: Are dyes used on cotton? ¶
A: Yes, and paper, leather, wool, silk and nylon.
Q: Are dyes inexpensive dyes used to dye cotton with dark colors? ¶
A: Yes.
Q: Were dyes obtained from animal? ¶
A: Yes, and vegetable or mineral origin, with none to very little processing.
Q: Are dyes also used in the coloration of paper? ¶
A: Yes.
Q: Are dyes water-soluble anionic dyes that are applied to fibers such as silk? ¶
A: Yes, and wool, nylon and modified acrylic fibers using neutral to acid dye baths.
Q: Are dyes mordant dyes and there is therefore a large literature base describing dyeing techniques? ¶
A: Yes.
Q: Is a dye produced directly onto or within the fiber? ¶
A: Yes.
Q: Are dyes classified according to their solubility and chemical properties? ¶
A: Yes.
Q: Are dyes usually soluble in water whereas pigments are insoluble? ¶
A: Yes.
Q: Are dyes by far the best choice for dyeing cotton and other cellulose fibers at home or in the art studio? ¶
A: Yes.
Q: Are dyes organic compounds? ¶
A: Yes.
