Textile Pretreatment Agent – APEO free low foaming wetting agent and detergent with excellent emulsifying action for use in exhaust pretreatment process of textile made of cellulosic, synthetic fiber and their blends.

Chemical Nature : Mixture of Non-ionic surfactants.

Features

• Colourless to slightly yellowish clear liquid miscible with water in all proportions.
• Concentrated wetting agent and detergent.
• Equivalent to NPEO in emulsification and detergency.
• Higher dynamic wetting as compared to NPEO.
• Exhibits rapid wetting, emulsifying and dispersing action.
• Phosphorous free.
• Low foaming.
• Resistant up to 30 g/l Caustic 100% at room temperature.
• Low odour.

Benefits

• Rapid wet out of hydrophobic fabric.
• Removes oily and greasy impurities as well as soluble sizing and soil particles.
• Results in good absorbency.
• Compatible with de-sizing enzymes.
• Shear stable. Suitable for machines that generate high turbulence.
• Best in class for wetting, detergency, emulsifying and low foaming. 4 in 1 product.
• Concentrated product so low dosage required.
• Compatible with other textile chemicals since it is non-ionic in nature.
• Results in higher degree of whiteness.
• Results in even and brilliant dyeing.
• Results in less rejections.
