Reactive Ink

To achieve professional-grade vibrancy and durability on natural fibers, following the correct reactive ink printing process is essential. Here is the standard industrial workflow:

Step 1: Pre-treatment (Coating)

Reactive dyes cannot bond directly to raw fabric. The fabric must be pre-treated (padded) with a specific coating solution containing alkali, urea, and thickeners. This preparation ensures:

Optimal ink absorption and prevents bleeding.

Controlled chemical reaction between the ink and the fibers.

Sharpness of fine lines and complex patterns.

Step 2: Digital Inkjet Printing

Using Print-Rite High-Density Reactive Ink, the design is jetted directly onto the pre-treated fabric. Our ink is engineered for:

Precision: Compatible with high-frequency industrial heads (Kyocera, Ricoh, Epson).

Stability: Continuous jetting without clogging, even during 24/7 production runs.

Step 3: Steaming (Fixation)

The printed fabric is then placed in a steamer. The high-temperature steam (typically 102°C - 105°C for 8-12 minutes) triggers the chemical reaction where the reactive dye molecules form a covalent bond with the cellulose or protein fibers.

Result: The color becomes an integral part of the fabric, ensuring it won't peel or crack.

Step 4: Washing & Drying

The final step involves a thorough washing process to remove excess chemicals and any unfixed dye.

Soaping: Enhances color brilliance and ensures the fabric reaches its peak wash fastness (Grade 4-5).

Softening: Restores the natural soft hand-feel of silk, cotton, or cashmere.

Drying: Final tension-controlled drying for a perfect finish.
