Question

The difference between a dye and a pigment is that a dye:

• A. is held to the surface of the fiber by a resin.
• B. is an inorganic chemical that permeates fibers..
• C. usually diffuses into the interior of a fiber from a water solution.
• D. lays on the surface of the fiber.

Answer 1

The correct option is C usually diffuses into the interior of a fiber from a water solution.

A 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.
Hence option C is correct.
