Textile Pretreatment Wetting Agent – Leomine Wash DNC

Textile Pretreatment Wetting Agent – Low foaming powerful wetting agent and detergent with emulsifying extractive action for mobilizing and removing impurities in cotton during pretreatment process. It also acts as a co-stabilizer in peroxide bleaching. Recommended for Continuous process.

Chemical Nature : Mixture of sequestering agents and surfactants

Features

• Colorless to pale yellow liquid with low viscosity ; pumpable
• Soluble in water in all proportions
• Low foaming
• Non-hazardous ; low toxicity
• Effective detergent
• Unaffected by electrolytes
• Low Odor
• Stable on storage

Benefits

• Excellent wetting, emulsification and dispersing action in one product
• Leomine Wash DNC extracts hard water salts, catalytic substances and pectins
• Remove fiber impurities and degraded sizes during desizing and boiling-off
• Prevents precipitation of alkaline earth carbonates during bleaching
• Better alternative to APEO containing detergents
• Compatible with Apha Amylase enzymes
• Faster penetration into fabric due to faster deaeration
• More even coloration in dyeing due to uniform pretreatment
• Can be used in all pre-treatment process – de-sizing, Scouring, Stain removing and bleaching
• Suitable for cold bleaching

Ecology

This textile pretreatment wetting agent is readily biodegradable. According to our experience Leomine Wash DNC does not exert any harmful effects on health provided it is used as per our recommendation. Does not contain APEO / NPEO.

Storage

Leomine Wash DNC has a shelf life of at least one year if stored in its tightly sealed original packing at temperatures between 5ºC 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.
