Formaldehyde-free Fixing Agent is a high-performance, eco-friendly color fixing additive developed for reactive, direct and acid dyes in the textile dyeing and finishing industry. It effectively binds dye molecules onto the fiber, significantly improving wash fastness, rub fastness and perspiration fastness while releasing no formaldehyde during the whole process.
This product is widely used in cotton knit and woven fabrics, rayon and viscose, silk and wool, blended fabrics, printing, yarn and garment dyeing. It provides good fixing performance, low foam, easy use, non-hazardous property and good compatibility.
Our formaldehyde-free fixing agent is produced under strict process control. It is available in different grades according to fiber type, dye class, shade depth, fastness target, application equipment and production requirement. Each batch is inspected for appearance, solid content, pH value, water solubility, fixing performance and fastness result before shipment.
We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and dosage according to your dyeing system, operation condition and destination country regulations.

POINTS FOR ATTENTION
For new customers, we recommend a small trial batch first to verify formaldehyde-free fixing agent performance in your actual dyeing line and pre-review export documents before bulk order.
The recommended dosage varies by application, typically from 2.0% to 5.0% owf. Start from lower dosage and adjust according to test result and operation condition.
Add product at suitable stage according to recommended method (exhaust or pad-batch). Ensure good dispersion and uniform distribution.
Keep bath pH within recommended range to ensure stable fixing performance and minimize color change.
Before mass use, test compatibility with other auxiliaries and dye system. Observe fixing performance, color change and system stability.
Keep sealed in a cool, dry and ventilated warehouse. Avoid direct sunlight and high temperature. It is non-dangerous goods for shipping.
Wear protective gloves, goggles and protective clothing during handling. Avoid contact with skin and eyes. If splashed into eyes, rinse with plenty of clean water immediately.
