Formaldehyde-free Fixing Agent is a high-performance textile auxiliary designed to improve color fastness of dyed textiles without using formaldehyde-containing components. It helps fix dyes on fibers, reduce color bleeding and washing off, and improve wet rubbing fastness, washing fastness and perspiration fastness.
This product is widely used in reactive dyeing, direct dyeing, acid dyeing and garment dyeing processes. It offers good fixing effect, low yellowing, high stability and easy handling. It can be applied in combination with various dye systems and improves the overall quality and reproducibility of dyed textiles.
Our formaldehyde-free fixing agent is produced under strict process control. It is available in different grades according to dye type, fiber material, dyeing process and application requirement. Each batch is inspected for appearance, pH value, viscosity, active content, formaldehyde content and fixing performance 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 dye system, fiber material, production process 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 system and pre-review export documents before bulk order.
The recommended dosage varies by application, typically from 0.5% to 3.0% o.w.f. Start from lower dosage and adjust according to trial result and production condition.
Add formaldehyde-free fixing agent after dyeing or in the final fixing bath. Ensure good circulation and uniform distribution in treatment bath.
Before mass production, test compatibility with dyes, auxiliaries, pH value and temperature. Observe stability, yellowing and fastness result.
Adjust grade and dosage according to dye type, fiber material, liquor ratio, temperature and treatment process. Control pH and circulation condition properly.
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.
