I. Core Advantages
Characteristics Feature Traditional Reducing Agents SILIT-PPN
Eco-Friendliness Contains sulfides or oxalic acid, may release harmful gases Free of formaldehyde, APEO, and heavy metals, compliant with OEKO-TEX 100 standard
Efficiency Slow reaction, requires high temperature conditions Quick neutralization at room temperature - 50℃, saving energy consumption
Safety Strongly acidic, requires protection during operation pH 2.0 - 4.0, low irritability, improving the workshop environment
Cost-Effectiveness Large dosage, high cost for wastewater treatment High-concentration formula, effective with a low dosage of 0.3 - 1.0g/L
II. Application Scenarios
Neutralization after Spraying Potassium Permanganate
Used to remove the manganese dioxide precipitation remaining after spraying potassium permanganate (PP Spray) on denim fabric, restoring the cleanliness of the fabric.
Post-treatment of the Snowflake Effect (Frying Snowflakes)
After the process of creating snowflake spots through pumice abrasion, it neutralizes the oxidant and stabilizes the color to prevent yellowing.
III. Product Performance and Parameters
Parameters Parameter Value
Appearance White crystalline powder
pH value (1% aqueous solution) 2.0 - 4.0
Solubility Readily soluble in water
Recommended Dosage 0.3 - 1.0g/L (adjusted according to the process)
Operating Temperature Room temperature - 50℃, optimal at 40℃
Treatment Time 5 - 15 minutes
IV. Operation Guidelines
Process Flow:
Potassium Permanganate Spraying/Snowflake Treatment → Water Washing → SILIT-PPN Neutralization (40℃, 10 minutes) → Secondary Water Washing → Drying
Precautions:
Avoid direct contact with strong oxidants, strong acids, and strong alkalis.
Seal and store after use to prevent moisture absorption and caking.
V. Safety and Environmental Protection
Compliance Certification: Certified by OEKO-TEX Standard 100, free of internationally prohibited substances.
Wastewater Treatment: No sulfide emissions, reducing the burden of sewage treatment.
Workshop Environment: No irritating odor, improving the working conditions for workers.
VI. Frequently Asked Questions (FAQ)
Q: Can SILIT-PPN replace oxalic acid?
A: Absolutely. Compared with oxalic acid, SILIT-PPN reacts faster, requires a lower dosage, and has no risk of corrosion.
VII. Obtaining Samples and Technical Support
Global Export: More than 20 countries including India, Pakistan, Bangladesh, Türkiye, etc.
