Reactive Dye

Reactive Dye

Reactive dyes are unique in their ability to form covalent bonds with fiber macromolecules, making them ideal for dyeing cellulosic-based materials such as cotton, viscose, linen, lyocell, and bamboo.

Applications:

• Fabric dyeing and printing

• Home textiles, apparel, technical textiles

Benefits:

• Excellent wash and light fastness

• Bright, vivid shades

• Compatibility with eco-friendly dyeing processes

Reactive Dyes for Printing

Reactive dyes used in textile printing are designed to form covalent bonds with cellulosic fibers such as cotton, viscose, linen, lyocell, and bamboo. These dyes offer:

• Bright and vivid colors

• Excellent wash and light fastness

• Strong fixation through chemical bonding

Common Reactive Dye Series for Printing:

• BETAFIX P-Series: Padding-compatible, high fixation

• ULTRA RGB Series: High reactivity, excellent post-wash stability

• XLDP Series: Enhanced soap resistance, sharp contour retention

• PX-Series: Designed for thermofixation and digital printing

Printing Processes with Reactive Dyes

Typical Print Paste Components:

• Reactive dye

• Sodium alginate (thickener)

• Urea (moisture retention)

• Soda ash (alkalinity)

• Water or glycol-based solvents

Reactive Dyeing Methods

Reactive dyeing methods vary depending on the dye type, fiber, and desired outcome:

1. Exhaust Dyeing

• Fabric immersed in dye bath

• Controlled temperature and pH

• Ideal for batch dyeing of garments or yarns

2. Pad-Batch / Pad-Dry

• Fabric padded with dye solution

• Batched at room temperature or dried before fixation

• Suitable for continuous operations

3. Pad-Steam

• Fabric padded and steamed for fixation

• Enhances dye-fiber bonding

• Common in printing lines

4. Thermofixation

• Dye fixed via dry heat (160–180°C)

• Used for PX-series and digital reactive inks

5. Post-Dyeing Wash & Soap

• Removes unfixed dye

• Improves fastness and clarity

• Essential for printed fabrics
