Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber.

After the discovery of the tomb, scientists have found many deteriorated paintings caused by water damage, bacterial growth, salt formation, and recently, the humidity of visitors'breath.
