Dyeing is the application of coloring substances like dyes or pigments on textile materials such as fibers, yarns, fabrics, garments, etc. to achieve an even color throughout the material. A good dyed material should have good colorfastness properties. Dyeing is generally conducted in a solution having chemicals, dyes, and water. To complete the dyeing process, we need several steps. Exhaustion and fixations are the most common steps among them. Usually, dyes make physical or chemical bonds with textile materials.
The dyeing process covers a lot of areas. An expert dyeing master should have clear knowledge about chemicals with their functions. Chemicals can be classified into sub-class based on the importance of the dyeing process. Moreover, all coloring substances are not suitable for all textile materials. A particular dye or pigment is applicable for some fixed fibers. Again, the procedure of dyeing fiber, yarn, fabric, and garments are not the same. There are some special features of each procedure. Furthermore, we can dye one material in many different ways. A dyeing professional must have all this necessary knowledge.
Dyeing is different from the printing process although the basic objectives of the two processes are the same. In the printing process, a coloring substance is applied in a particular area of the textile materials to produce a particular impression but in dyeing a continuous color is produced throughout the material.
