Direct dyes are also known as substantive dyes and are quite cost-effective. They can fabricate bright colors and are extremely easy to apply. Direct dyes exhibit poor wash fastness, however, after treatment procedures, they can be easily refined and the wash fastness can be significantly improved. Due to this, direct dyes are considered as after-treated direct colors. They can easily adhere to the fabric molecules without needing any help from other types of chemicals.

Direct dyes can also be defined as anionic dyes as they exhibit substantively for cellulosic fibers by applying the aqueous dye bath that consists of an electrolyte, sodium sulfate, or sodium chloride. Their applications can be found in multiple industries such as wool, nylon, leather, paper, silk, and cotton. They are also used for inkjet printing and can be used as pH indicators for biological stains.

What is the Dyeing Process When Using Direct Dyes?

Using direct dyes for dyeing is a very simple process. The entire process is carried out in a slight alkaline dye bath near the boiling point. However, a different after-treatment process such as cationic dye fixing is implemented. This is undertaken to enhance the wet fastness which is required while using direct dyes.

On What Basis are Dyes Selected for Papers?

There are multiple properties that need to be possessed by the dye in order for it to be suitably used in the paper industry. A few of them consist of good affinity, light fastness, bleed fastness, stability to humidity and temperature, right shade, clear backwaters, regulatory compliance, optimum depth, absence of impact on other paper parameters or processes, and is safe to handle.
