What is Fabric Dyeing?
Dyeing is a method which imparts beauty to the textile by applying various colors and their shades on to a fabric. Dyeing can be done at any stage of the manufacturing of textile, such as fiber, yarn, fabric or a finished textile product including garments and apparels. Fabric may be dyed in all its forms, such as woven, non‐woven and knitted fabrics or as hosiery or garments.
Fabric dyeing, also called piece dyeing, is the most popular production method for solid color, as it gives the greatest flexibility to the manufacturer in terms of inventory as well as production capacity. Large orders of woven fabric can be dyed in a continuous process, i.e., pad dyeing, while the batchwise jig dyeing is suitable for small batch production. For tension-sensitive materials, such as knitted fabrics or some thin woven fabrics, the batchwise process of winch dyeing and jet dyeing are the most appropriate dyeing methods.
Different types of chemicals and auxiliaries are used during dyeing fabric. In previous article we have discussed about textile yarn dyeing chemicals and auxiliaries. Now, I will give a list of chemicals and auxiliaries with their function in case of fabric dyeing.
List of Chemicals and Auxiliaries Used for Fabric Dyeing:
|Chemicals & Auxiliaries||Commonly Used Chemical with it’s Trade Name||Function|
|Solublizing Agent||Urea||Increase the solubility of dyes|
Controls the sublimation at high temperature
|Reduction Inhibitor||Lyoprint RG or Resist Salt||Mild oxidizing agent, controls the reduction of dyes at high temperature or during steaming.|
|Caustic||Controls the rate of reaction between dyes and cellulose or in other words it is used for fixation of Reactive Dyes.|
|Soda Ash||Controls the rate of reaction between dyes and cellulose or in other words it is used for fixation of Reactive Dyes.|
Increases the fastness properties if used in washing
|Sodium-bi-Carbonate||Controls the rate of reaction between dyes and cellulose or in other words it is used for fixation of Reactive Dyes.|
|Binding Agent||Helizarin Binder ETS|
Imperon Binder MTP
|Use as an adhesive to fix the pigment dyes on cotton fiber at high temperature.|
|Wetting Agent||Cibaflow Pad|
|To increase the wettability of fabric and penetration of dyes in the fiber.|
|Dispersing Agent||Setamol BL|
|Used for dispersing of disperse and vat dyes.|
|Antifoaming Agent||Antimusol SF|
|Used to prevent formation of foam during stirring or during dyeing in one bath.|
|Anti-migrating Agent||Irgapadol MP|
|Increases the viscosity of dyeing liquor to protect migration of dyes under high temperature.|
|Electrolyte||Glauber Salt||Decreases solubility of dyes in liquor|
Increases affinity between dyes and fiber under moist condition
