General Information
- Product Name: Formaldehyde-Free Fixing Agent (QAC-TEX001)
- Catalog: QAC-TEX001
- Type: Quaternary ammonium polymer
- Applications: Textiles
Description
Alfa Chemistry's formaldehyde-free fixing agent is a kind of quaternary ammonium polymer developed to improve the color fastness of fabrics dyed with reactive and direct dyes. The product contains reactive groups in its molecular structure that bind effectively with both dyes and fibers, ensuring better fixation and long-lasting color retention. The absence of free formaldehyde makes it ideal for environmentally conscious operations in the textile industry.
Performance Characteristics
- High Concentration: QAC-TEX001 is a highly concentrated fixing agent, typically diluted to 20% solid content for regular use, providing potent dye fixation with minimal product required.
- Formaldehyde-Free: It ensures no formaldehyde contamination, making it safe for both workers and consumers, while meeting eco-friendly standards.
- Excellent Wash Fastness: It offers superior soap wash fastness, preventing dye loss during post-dyeing treatments.

Applications
Alfa Chemistry's formaldehyde-free fixing agent is primarily used in the dyeing and printing industries, where it provides enhanced color fastness. It is especially effective in fixing reactive dyes and direct dyes.
Brief Usage Instructions
- Dilution: Dilute the QAC-TEX001 agent to a 20% solid content before use.
- Recommended Dosage: Use 0.5-1% (O.W.F) of the agent, based on the fabric's weight. This lower dosage is ideal for full, even fixation while minimizing product usage.
- Recommended Dosage: Use 1-5 g/L of the agent in the padding solution. This dosage is more concentrated to ensure efficient application through the padding process.
- Roller Retention Rate: 80-90% of the applied agent should remain on the fabric after the padding process, ensuring optimal fixation and high retention of the fixing agent.
The dosage and process should be adjusted based on fabric type and dyeing conditions, with trial runs recommended for best results.
Packaging and Storage
- Packaging: Available in 50KG and 200KG plastic barrels.
- Storage Conditions: Store in a cool, dry place at room temperature to maintain product quality.
- Shelf Life: 6 months from the date of manufacture, provided it is stored properly.
