Polyester Fixing Agent HN-860

Oxygen in the air, under the catalysis of light, causes yellowing and shade change of disperse dyes on polyester fiber surfaces. Particularly for disperse dyes with poor sublimation fastness, during high-temperature setting, some dye inside the fiber migrates to the fiber surface, which reduces washing fastness and dry/wet rubbing fastness. Shade change is also prone to occur on light shades and sensitive color combinations. These issues are especially prominent when dyeing polyester fabrics. For orders with high fastness requirements, dye houses typically use the process: polyester dyeing → reduction cleaning → intermediate setting → reduction cleaning → setting. Polyester dyeing requires two setting processes, which increases production steps, electricity costs, and introduces uncertainties. Our company's Polyester Fixing Agent effectively solves the above problems.

Appearance

Slightly yellow transparent liquid

pH value

7.0 ± 0.5 (1% aqueous solution)

Ionicity

Cationic

1. A cationic polymer fixing agent with excellent fixing performance, suitable for pure polyester and polyester/cotton blended fabrics.

2. No dye bleeding in the bath after fixing; does not alter fabric color.

3. Fabrics after fixing are more hydrophilic compared to traditional fixing agents, have minimal impact on hand feel, and are easy to strip.

4. Formaldehyde-free, belonging to green and environmentally friendly auxiliaries.

1. Pure Polyester Fabric
Padding process: 10–30 g/L, one dip one nip, drying at 130–170°C for 100–120 seconds.
2. Polyester/Cotton Blends
·It is recommended to select the appropriate dosage based on the polyester content. If the polyester content is high, reduce the dosage appropriately (higher dosage may reduce fastness). If the cotton content is high, increase the fixing agent dosage appropriately to achieve good fixing results.
·Padding process: 10–30 g/L, one dip one nip, drying at 130–170°C for 100–120 seconds.
The above methods are for reference only. Adjust according to actual factory processes. This product can also be diluted; adjust the dilution ratio according to actual requirements.

Packaged in polyethylene plastic drums with inner plastic liner, 125 kg per drum.
Store in a cool, dry, well-ventilated warehouse. Shelf life: 6 months.
