Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Every textile product has a unique dyeing flow chart. Such as fiber dyeing flow chart, yarn dyeing flow chart, fabric dyeing flowchart, etc. In this article, I will show the fabric dyeing flow chart. It is also called the common flow chart of dyeing. In previous, we have discussed flow chart of woven dyeing, knit dyeing, and yarn dyeing. Now we going to discuss the flow chart of fabric dyeing are as follows:

“The process of applying color to fiber stock, yarn, or fabric is called dyeing.” Dyes can be used on vegetable, animal, or man-made fibers. Textile dyes include acid dyes, used mainly for dyeing wool, silk, and nylon, and direct or substantive dyes. Mordant dyes require the addition of chemical substances, such as salts to give them an affinity for the material being dyed. They are applied to cellulose fibers, wool, or silk after such materials have been treated with metal salts.
Sulfur dyes, used to dye cellulose, are inexpensive but produce colors lacking brilliance. Azoic dyes are insoluble pigments formed within the fiber by padding, first with a soluble coupling compound and then with a diazotized base. Vat dyes, insoluble in water, are converted into soluble colorless compounds by means of alkaline sodium hydrosulfite. These colorless compounds are absorbed by the cellulose, which is subsequently oxidized to an insoluble pigment. Such dyes are colorfast. Disperse dyes are suspensions of finely divided insoluble. Organic pigments used to dye such hydrophobic fibers as polyesters, nylon, and cellulose acetates. Different types of dyes are used in fabric to produce garments.
