What is Mordant?

Mordant is a substance used in tissue and tissue dyeing that allows the dye to stick to the substrate. Tissue clothing and samples can be dyed without mordant and the dye may seem quite vivid. However, if the clothing or tissue is exposed to water, the dye is washed immediately. Mordants work by creating a coordination complex or metal binding with a coloring cloth. Many substances are called mordants and play the same role, but they are not technically mordants; Real mordants are metal molecules with valence of two or higher and most often three. This substance is able to change the color of the fabric or tissue, so the fabric is more attractive to wear and tissue is easier to see under the microscope. While the dye will hold firmly on the fabric or tissue, the water is able to quickly rinse the dye, so the dye temporarily.

Mordants are used to ENSUR's stormity. Mordant is a substance that is used in conjunction with dye to chemical binding of dye to the surface. This is done through a coordination complex. In the coordination koMplex, metal atoms from a mordant bond with nearby dye, creating a strong binding that water cannot easily fall apart.

There are three ways to apply Mordant. In pre-mordanting, the substrate encounters a mordant and then is stained. Meta-mording combines mordants and dyes, so both are mixed together in the same dye. After mording, the process of introducing the Mordant after the substrate is colored.

Many substances used during the dyeing process are called mordants, but they are not really mordants. These are tracker agents that inhibit the removal of the dye, while the mordants are able to completely stop removal. Trapping agents are often non -acts and can be Myed with greater variety of dyes.

real mordants must be metal. Metal valence or the ability to create chemical ties must be two or higher. Usually as mordants are used metals such as iron and aluminum, and both of these metaly have a valence of three. The metal is needed to create an intense binding between the mordant and the dye, because otherwise the coordination complex cannot be completed.
