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.
2. Dye migrating property test
[Dyeing conditions]
Substrate: polyester tropical
- Dyestuff
Dianix Yellow G-FS 2.0%o.w.f.
Dianix Red KB-SE 1.0%o.w.f.
Dianix Blue BG-FS 0.5%o.w.f.
- Acetic acid (90%) 0.3mL/L
- Liquor ratio1:20
- Temperature x time 130°C x 60min
[Migrating conditions]
Substrate: the above fabric (dyed, 2.5g) +polyester tropical (not dyed, 2.5g)
- Dispersing/leveling agent (g/L)
- Acetic acid (90%) 0.3mL/L
- Liquor ratio 1:20
- Temperature x time 130°C x 30min
[Evaluation]
Color of the substrate was measured using a CCM system (SICOMUC 20: Sumika Chemical Analysis Service). The ratio of color concentration (%) was examined in comparison to that of the same fabric before the test (=100). Higher values denote higher concentrations, indicating superior properties.
