Usage Instructions

ER-330 Anti-freeze Nylon Fluorescent Brightener (Liquid) should be used according to the following guidelines for good results:

1. Immersion Dyeing:
   - Recommended Dosage: Use 0.2-5% (o.w.f), with the good range being 0.5-1.5% (o.w.f).
   - Application Conditions: Adjust the pH to 5.5-6.0 using citric or acetic acid. Use a bath ratio of 1:10-20, dye at 80-100°C for 30-40 minutes, then rinse thoroughly and dry.

2. Padding Thermosol Method:
   - Mixing Instructions: Use 1.5-10.0 grams per liter, adjusting based on small sample tests.
   - Application Process: Perform two dips and two nips (70-80% pick-up rate), pre-dry at 100°C, and then heat-set at 160-170°C for 30-40 seconds.

3. Low-temperature Adsorption High-temperature Color Development:
   - Application Recipe: Use 0.5-1.2% (o.w.f), adjusting pH to 5.0-6.5 with citric or acetic acid.
   - Application Conditions: Use a bath ratio of 1:10-20, and dye at 50-60°C for 20-30 minutes. Add ER-330 Anti-freeze Nylon Fluorescent Brightener (Liquid) and sodium dithionite (1-3% o.w.f), adjust pH to 6, raise temperature to 50°C, dye for 20-30 minutes, then rinse, dehydrate, pre-dry at 100°C, and heat-set at 180-190°C for 30-40 seconds.

By following these guidelines, users can achieve good whitening effects and maintain high-quality results across various textile applications. ER-330 Anti-freeze Nylon Fluorescent Brightener (Liquid) ensures that nylon fibers and other textiles maintain their bright and vibrant appearance throughout their lifecycle.
