Dispersing/leveling agent for high-pressure dyeing of polyester
Benerap D-101
Performance Evaluation
Ipposha has conducted tests on the dispersibility, dye migrating/retarding properties, decoloration, chemical stability and foaming properties of Benerap D-101, a dispersing/leveling agent for the high-pressure dyeing of polyester. The following shows the result.
4. Decoloration test
[Test conditions]
Substrate: polyester tropical
- Dyestuff
Kayalon Polyester Blue T-S 0.1%o.w.f.
- Dispersing/leveling agent 0.5g/L
- Acetic acid (90%) 0.3mL/L
- Liquor ratio 1:20
- Temperature x time 130°C x 60min, 130°C x 120min
[Evaluation]
Color of the substrate was measured using a CCM system (SICOMUC 20: Sumika Chemical Analysis Service). Differences in a-value to that of a base fabric dyed without the use of a dispersing/leveling agent were observed. The closer the value is to zero, the less color is lost, indicating less influence on dyestuff.
