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.
1. Dispersibility test
1-1. Casing spot test
[Test method]
Substrate: polyester double pique
Device used: Colorpet 12
[Dyeing conditions]
- Dyestuff
BORON RED R153# 200% 1.5%o.w.f.(made in China)
Dianix Blue S-2R 2.0%o.w.f.
Sumikaron Navy Blue S-2GL 2.0%o.w.f.
Sumikaron Yellow S-RPD 3.0%o.w.f.
- Dispersing/leveling agent (g/L)
- Acetic acid (90%) 0.3ml/L
- Liquor ratio 1:20
- Temperature x time 90°C x 0min, 120°C x 0min, 130°C x 0min
[Evaluation]
The condition of dyed fabric, which was wrapped around a perforated holder, was visually examined, after the temperature was raised to 90°C, 120°C or 130°C then cooled immediately.

[Test method]
- Dyestuff
Dianix Blue S-2R 1g/L
Dianix Red KB-SE 200% 1g/L
- Dispersing/leveling agent 0.5, 1.0g/L
- Acetic acid (90%) 0.3 mL/L
- Temperature x time 130°C x 60min
[Evaluation]
After conducting treatment under the above conditions, the test liquor was cooled to 90°C and then stirred for 20 minutes, before carrying out suction filtration with No.5A filtration paper to examine the amount of residue. A smaller amount of residue denotes less coagulation, thus indicating superior dispersibility.
 :No residue (good dispersibility)
|
x :Large amount of residue (poor dispersibility)
