High-temperature leveling agent QT-501 is a new type of high-temperature dispersion leveling agent developed for polyester fiber (polyester fiber), which prominently strengthens multiple functions such as the dispersibility, migration property, retarding property, leveling property, and foam-free property of the auxiliary agent. Meanwhile, the dyed product has bright color, correct shade, high final dye uptake, and is easy to match colors; this product has no color fading property, excellent reproducibility, and can be used with confidence from light to dark colors. It does not contain APEO and formaldehyde.
- Excellent dispersibility, preventing dye agglomeration.
- Superior migration and retarding properties.
- Low color fading, good reproducibility, and low mechanical staining.
- Suitable for polyester cheese yarn dyeing. Due to its strong diffusibility and migration property, it can effectively avoid the problem of difference between the inner and outer layers of the cheese yarn.
- Recommended process: Add directly into the dye vat during dyeing.
- Recommended dosage:
- Ultra-fine denier fabric: 1.0 - 1.5% (o.w.f)
- Ordinary fabric: 0.5 - 1.5% (o.w.f)
Add and stir evenly before adding the dye → add the dye → adjust the pH → heat up (105 - 135℃ depending on the dye type) → heat preservation and dyeing... → cool down → drain → neutralize... → dehydrate and dry.
- Conduct a small sample test in advance to determine the optimal dosage.
- If used in the same bath with other finishing agents, conduct a compatibility test in advance.
- Store in a cool, dry, and ventilated place, protected from sunlight and rain. The shelf life is 6 months.
- Polyethylene plastic barrel, lined with a plastic bag, 125KG per barrel.
