Product Advantage
1. Superior Levelling Performance: Reduces dyeing unevenness by over 90% (tested on 50+ fabric types). It slows down initial dye uptake by 30%-40%, allowing uniform color spread, ideal for batch dyeing of blended fabrics.
2. Broad Compatibility: Compatible with 95% of reactive, disperse, and acid dyes (verified in 100+ formulations). Works seamlessly with auxiliaries like penetrants and fixatives in textile dyeing.
3. Wide pH Adaptability: Maintains stability in pH 3-9 (tested over 24 hours). Performs well in acid dyeing for wool and weak alkali processes for cotton, reducing process adjustment needs.
4. Enhanced Dye Utilization: Improves dye absorption rate by 15%-20% (data from industrial trials), lowering dye dosage and wastewater colority, supporting eco-friendly production.

Product Uses
1. Cotton Fabric Dyeing: In reactive dyeing of cotton, it ensures uniform color absorption, reducing streak formation by 80% (industrial data). Works well in weak alkali baths, enhancing dye penetration into fibers for consistent shades.
2. Wool Dyeing: Optimizes acid dye distribution on wool, preventing uneven uptake due to fiber diameter differences. Improves color fastness to washing by 1-2 grades in textile tests.
3. Polyester-Cotton Blends: Balances dyeing rates of polyester and cotton components in disperse/reactive dye systems. Reduces color difference between fibers by ΔE < 1.5 (colorimeter measured)
4. Nylon dyeing: This process helps the acidic dyes evenly adhere to the nylon fibers, thereby minimizing the differences between batches. It is suitable for dyeing socks and clothing, ensuring uniform color and softness.
Product Operate Guide
For Levelling Agent O-25, add 0.2%-1% to dye bath (adjust by fabric type). Stir to dissolve, then add fabric. Maintain 40-80℃ during dyeing. Avoid mixing with strong acids. Seal and store in cool place after use. Stir well before reuse if caked.
FAQ
1. What's the proper dosage of Levelling Agent O-25?
It's 0.2%-1% of fabric weight. For cotton, 0.5%-1% is better; for wool/nylon, 0.2%-0.5% suffices. Test with 1kg fabric first to avoid waste.
2. Can it work with all dye types?
Effective with reactive, acid, and disperse dyes. Not ideal for vat dyes. Test compatibility by mixing 10mL dye and 1mL agent—no precipitation means usable.
3. How to handle poor leveling results?
Check dosage (too low causes unevenness) and temperature (below 40℃ reduces activity). Increase agent by 0.2% or raise temp to 60-80℃, then retest.
