Texnology® RH58 Anti‑Staining Soaping Agent for White Ground works during washing of printed or dyed fabrics. It removes floating dyes quickly and stops them from re‑staining the fabric or background. This ensures good color fastness and a clean background. It gives strong anti‑staining on white ground. For striped fabrics, it removes floating dyes from different colors effectively. It wraps the dyes tightly and prevents cross‑staining. If cross‑staining already happened, it removes the migrated dyes as well. It keeps the shade bright. It has strong affinity for dyes and acts as a strong protective colloid. It also gives powerful dispersion, emulsification, soaping, and anti‑backstaining effects. It suits removal of floating dyes after dyeing with direct, reactive, vat, or acid dyes. It does not affect the color shade. At the same time, it improves wet fastness on deep‑dyed fabrics. Finally, it shows good stability and resists acid, alkali, oxidants, and various electrolytes.
Application Process
Dyeing machine washing process – recipe:
(1) Room temperature. Add 0.5–1 g/L Texnology® RH58 and 0.6 g/L NaOH. Liquor ratio 1:20. Wash for 5 minutes, then rinse with clean water.
(2) Room temperature. Add 0.5–1 g/L Texnology® RH58 and 0.6 g/L NaOH. Liquor ratio 1:20. Wash for 10 minutes, then rinse with clean water.
(3) Room temperature. Add 0.5–1 g/L Texnology® RH58 and 0.6 g/L NaOH. Liquor ratio 1:20. Wash for 10 minutes, then rinse with clean water.
(4) 50°C. Add 0.5–1 g/L Texnology® RH58 and 0.6 g/L NaOH. Liquor ratio 1:20. Wash for 20 minutes, then rinse with clean water.
Open‑width washing machine process – recipe:
(1) First compartment – room temperature. Add 0.5–1 g/L Texnology® RH58 and 0.6 g/L NaOH.
(2) Second compartment – room temperature. Add 0.5–1 g/L Texnology® RH58 and 0.6 g/L NaOH.
(3) Third compartment – 50°C. Add 1–1.5 g/L Texnology® RH58 and 0.6 g/L NaOH.
(4) Fourth compartment – 50°C. Add 1–1.5 g/L Texnology® RH58 and 0.6 g/L NaOH.
(5) Fifth compartment – 50°C. Add 1–1.5 g/L Texnology® RH58 and 0.6 g/L NaOH.
(6) Sixth compartment – rinse with clean water.
(7) Seventh compartment – rinse with clean water.
Note: For compartments 1 and 2, use cold water at room temperature. For compartments 3, 4, and 5, you can raise the temperature appropriately to improve washing results based on actual conditions.
Alternative: You can replace caustic soda with soda ash according to your actual needs.
