What is Dyeing in Textile Wet Processing?

Dyeing is the process of imparting color to the textile fabric using chemical dyes called dyestuff in the aqueous medium. The dyestuff are capable of reacting and combining with the textile fiber molecule usually when in a water solution and usually with other auxiliary chemicals to enhance the process.

In the actual process, the water dye, chemicals and textile brought together for a period ranging from several minutes to several hours which are totally dependent upon the fibers being dyed and types of dye being used.

Types of Dye Used in Textile Dyeing:

There are so many dyes are used in textile wet processing sector. Those are in the below:

  1. Acid Dye,
  2. Natural Dye,
  3. Premetallized Dye,
  4. Metallized Dye,
  5. Pigment Dye,
  6. Disperse Dye,
  7. Macromolecular Dye,

Textile Dyeing Methods:
At first, the greige fabric is permitted pretreatment process to remove size materials, natural impurities and natural color make it suitable for dyeing. All the processes before dyeing include de-sizing process, scouring process and bleaching process. After completing these processes, finally the fabric is dyed by using the required dyes as per desired shade which is approved by the buyer. After that, dyed fabric should be washed and dried in the dryer.
