List of Chemicals and Auxiliaries Used for Fabric Dyeing

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.
Alkali

 

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

Kieralon A

Sandozin EH

To increase the wettability of fabric and penetration of dyes in the fiber.
Dispersing Agent Setamol BL

Setamol WA

Dispersogen P

Used for dispersing of disperse and vat dyes.
Antifoaming Agent Antimusol SF

Leonil KS-U

Used to prevent formation of foam during stirring or during dyeing in one bath.
Anti-migrating Agent Irgapadol MP

Size CA

Alginate

Emigen AS-U

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
