CRN REDUCTANT RN is a high-stability reducing agent derived from aminoimino sulfonic acid, specifically engineered for the high-efficiency reduction clearing of polyester fibers. It offers a more controlled and environmentally friendly alternative to traditional hydrosulfites, ensuring superior fastness without compromising the original color shade.

Why It Should Be Preferred?

• Thermal Stability: Maintains its reductive power at high temperatures where traditional agents often decompose prematurely.

• Selective Action: Precisely targets unfixed dye on the fiber surface without affecting the dye fixed inside the polymer matrix.

• Environmental & Workplace Safety: Odor-free and sulfur-dioxide-free application, providing a significantly better environment for operators.

• pH Versatility: Performs effectively across a wider pH range, allowing for potential "acidic reduction clearing" which saves time and water.

• Consistent Reproducibility: Due to its stable chemical nature, it delivers identical cleaning results batch after batch, reducing the need for re-washes.

Areas of Usage

• Polyester HT Dyeing: Post-dyeing cleaning to achieve international fastness standards (Grade 4-5).

• High-End Printing: Clearing excess paste and dye from printed polyester fabrics to maintain sharp designs and clean backgrounds.

• Complex Blends: Ideal for PES/Spandex or PES/Cotton blends where gentle yet effective cleaning is required to protect the companion fibers.
