Textile Dyeing:
Textile dyeing is a process of coloring or tinting textile materials such as fibers, yarns, fabrics, or garments. It is a combination of some series processes such as scouring, bleaching, dying, and after treatment which can be carried out at different stages of fiber processing in different forms like a staple, yarn, fabric, etc. In the dyeing process, lots of chemicals required. To become a successful dyeing engineer or dyeing master you should know some chemical formula that is widely used in different stages of dyeing. The chemical formula of common chemicals used in textile dyeing is as follows:
Chemical Formula of Common Chemicals Used in Textile Dyeing
Chemical Name and Their Formula:
- Water = H2O
- Hydrochloric Acid = HCl
- Sulfuric Acid = H2SO4
- Phosphoric Acid = H3PO4
- Sodium Chloride (common salt) = NaCl
- Sodium Carbonate = Na2CO3
- Sodium Sulfate (Glauber salt) = Na2SO4
- Sodium Bicarbonate = NaHCO3
- Sodium Hydroxide = NaOH
- Potassium Hydroxide = KOH
- Sulfur Dioxide = SO2
- Trisodium Phosphate = Na3PO4
- Benzene = C6H6
- Acetic Acid = CH3COOH
- Oxalic Acid = (COOH)2
- Cellulose = C6H10O5
- Starch = C6H10O5
- Hydroz (Sodium Hydrosulfite) = Na2S2O4
Chemicals are the most important materials for textile dyeing in both knit and woven fabrics. Every chemical is different in its own characteristics. In the dyeing machine, the dyes and chemicals are mixed in. Every chemical is not suitable for all types of dying. The specific dye needs a specific chemical. The application of chemicals depends on the types of dyes.
