Detailed info about solvent dyes and their usage!

A dye is a substance of color that gets dissolved in unrefined solvents, which helps in forming a solution. The dyes have non-polar nature, making it easy for them to get mixed with other substances. These colors are used in a range of products like; plastics and resins. Their frequent usage is seen in many industries like; the plastic manufacturing industry, which use such dyes and colors, in the making of different types of plastic goods.

The chemicals or substances, which can easily be mixed with other chemicals to form a solution, are solvents. However, such chemicals do not dissolved easily in water.  On the other hand, dyes are completely soluble, which means they will not form a separate layer, when mixed with other chemicals. The dyes provide consistent color due to their property of dissolving with other solvents.

Like other colors, a solvent dye does not ionize. Ionization is the ability of a compound to alter its divergence through gaining or losing an electron from other compounds. This is the reason why dyes do not dissolve in water.

There are different types of dyes, available in the market. There are azo dyes, which are available in yellow and red color.  These are commonly used synthetic dyes, which contain nitrogen. Apart from this, green and blue dyes are known as anthraquinone dyes.

These are chemicals with a molecular structure containing 14 carbons, 2 molecules of oxygen, and 8 molecules of hydrogen.

Now, let us have a look at two of the most popular types of dyes used by different industries for an array of reasons.

  1. Natural dyes- These are some of the best dyes available in the market, and which are obtained from natural sources like; tree bark, plants and wood. Natural dyes are used on a large scale by plastic manufacturing industries for creating colored plastic goods. During the Neolithic period colorants were used for different reasons. With the passage of time, the use of these colorants increases. Today, the use of colorants and dyes is seen throughout the world for multiple purposes.
  2. Synthetic dyes- The usage of these dyes increased significantly due to an array of reasons. William Henry Perkin is the man who discovered these dyes.

There are several benefits associated with synthetic dyes like the fact that extraction and production costs is lesser than natural dyes. Furthermore, these dyes have robust properties, when compared with natural dyes.
