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 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 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.
