PRODUCT INTRODUCTION
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

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Low Fixing Effect
Unsuitable grade, insufficient dosage or wrong process causes poor fastness.
Solution: Select suitable grade, increase dosage and optimize treatment process.
Color Bleeding and Washing Off
Poor dye fixation, wrong pH or temperature causes color bleeding.
Solution: Use appropriate fixing agent, adjust pH and temperature, and improve circulation.
Yellowing Problem
Unsuitable grade, high temperature or wrong pH causes yellowing.
Solution: Select low yellowing grade, reduce temperature and control pH properly.
Poor Compatibility with Dye System
Wrong grade causes precipitation, instability or poor fixing result.
Solution: Test compatibility before mass production and select matching grade.
Low Wet Rubbing Fastness
Poor dye fixation, insufficient washing or unsuitable fixing agent causes defects.
Solution: Improve washing process, use suitable fixing agent and optimize treatment condition.
Low Perspiration Fastness
Unsuitable grade, wrong pH or poor dye fixation causes perspiration fastness issue.
Solution: Select appropriate grade, adjust pH and optimize fixing process.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
High COD Load in Wastewater
High active content or excessive dosage increases wastewater treatment load.
Solution: Optimize dosage, use concentrated grade and cooperate with wastewater treatment.
