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
