Different coloration techniques for dyeing and printing industry

Coloration process of textile fibers are an essential portion in the textile industry. Actually, textile coloration means a wet process which is carried out using dyes, chemicals and a large volume of water. Textile coloration is the driving force of the textile industry because the quality of fabric depends on the coloration of textile fibers mostly.

There are lots of techniques for textile coloration. Some of them are conventional and some of them are modern.

According to the conventional technique, it is parted by-

• Electrochemical reaction

•  

• Electrochemical reduction by direct

•  

• Electrochemical reduction by an indirect process

•  

• Electrocatalytic hydrogenation.

According to modern techniques of coloration process of textile fibers are-

• Using nanoparticles

•  

• Using ScCO2 (Supercritical carbon dioxide)

•  

• Using plasma technology

•  

• Using microwave process

•  

• Using ultrasonic system

The conventional process is needed for a large volume of water. It is a big challenge for a wet process engineer to reduce the M:L ratio. Our Environment is getting polluted day by day due to dyeing factories chemicals water, and these techniques are a very lengthy process.

But modern techniques take less time and environment-friendly. To cap it all, these techniques do not require any kind of water. So, it is helpful to reduce the M:L ratio. So, in a broad sense, it is very much helpful for our dyeing sector.
