Textile Pretreatment Stabilizer – Leomine Stabilizer PSD

Textile Pretreatment Stabilizer – Concentrated Organic Stabilizer for bleaching cotton and polyester-cotton blends with hydrogen peroxide. Suitable for continuous processes.

Chemical Nature : Mixture of salts of organic polyacids

Features

• Clear yellowish brown liquid with low viscosity ; pumpable.
• Soluble in water in all proportions.
• Low foaming.
• Non-hazardous ; low toxicity.
• Resistant to electrolytes.
• Stable on storage.

Benefits

• Can be directly stirred in bleaching baths.
• Better alternative to Silicates.
• Suitable for Continuous bleaching range.
• Does not foam even at high processing speeds.
• Stabilizes hydrogen peroxide over longer period of time as compared to other stabilizers.
• Provides optimum fiber protection.
• Its dispersing action prevents impurities from cotton from re-deposition; aids their wash-off.
• Results in better whiteness after pre-treatment.
• More even coloration in dyeing due to uniform pre-treatment

Ecology

This textile pretreatment stabilizer is readily biodegradable. According to our experience Leomine Stabilizer PSD does not exert any harmful effects on health provided they are used as per our recommendation. Does not contain APEO / NPEO.

Storage

This textile pretreatment stabilizer has a shelf life of at-least one year if stored in its tightly sealed original packing at temperatures between 5 ºC and 35ºC in a dry place. Drums should be tightly resealed each time the material is taken from them, and their
contents should be used up as soon as possible after they have been opened.
