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.

3. Dye retarding property test

[Test conditions]

Substrate: polyester tropical

• Dyestuff
  Sumikaron Yellow SE-RPD 0.24%o.w.f.
  Sumikaron Red SE-RPD 0.16%o.w.f.
  Sumikaron Blue SE-RPD 0.08%o.w.f.
  
• Dispersing/leveling agent 0.5g/L
• Acetic acid (90%) 0.3mL/L
• Liquor ratio 1:20
• Temperature x time 40°C → 90°C, 100°C, 110°C, 120°C, 130°C, 130°C x 30min

[Evaluation]

Color of the dyed 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 a base fabric treated at 130°C for 30min without the use of a dispersing/leveling agent. Higher values denote higher concentration.
