Formaldehyde free fixing agent WPB

Brief information

-- Formaldehyde free fixing agent for reactive, direct and sulfur dyestuffs that obviously improves various fabric fastness.

Main composition

-- Polycationic compound.

General properties

-- Appearance:                     Light yellow to deep yellow viscous liquid

-- Ionicity:                          cationic

-- pH:                                 3-5

-- Solubility:                        easily soluble in water

-- Stability:                          stable to acid, alkali, electrolytes and hard water

Properties and fields of application

-- Negligible shade fades to efficiently prevent low stripping and shade change.

-- Slight shade change and does not affect original shades.

-- Obviously improves rubbing, soaping and perspiration fastness.

-- Outstanding alkali resistance that makes mercerization available after fixing.

-- Free of formaldehyde that complies with environmental requirements.

-- Resistant to chlorine bleaching.

Application

-- High concentration product and can be diluted 5-7 times.

-- To guarantee subsequent fixing performance, please rinse the dyed fabrics completely to remove residual dyestuffs, salts and alkalis before fixing. Soaps if necessary.
