HTFIX 806

(Wet rubbing fastness improving agent)

 

Brief information

-- A special wet rubbing fastness improving agent for direct, reactive and sulfur dyestuffs whose wet rubbing fastness is low for deep shades, especially dark black, bright red and turquoise blue whose wet rubbing fastness is below Grade 3, while fabric wet rubbing fastness exported to Europe and US must be above Grade 3.

 

Main composition

-- Special water-based polyurethane.

 

General properties

-- Appearance:                      light yellow to yellow liquid

-- Ionicity:                          weakly cationic

-- pH:                                 4.5 ± 1

-- Solubility:                         easily soluble in normal water in any proportion at room temperature

 

Properties and fields of application

-- Does not destroy fabric fastness, neither shades nor hand feels.

-- Excellent wet rubbing fastness improving performance that can meet above Grade 3 by improving 1- 2 grades for cellulose fibres with reactive dyestuffs.

-- No influence on light fastness and resistant to washing.

-- Free of formaldehyde and APEO that complies with environmental requirement.

-- Easy operation for using by direct dilution and good stability without oil floating.

 

Application

-- Dipping:                           1-4% (O.W.F)

Bath ratio:                         1: 10 – 20

Dyed fabrics (pH ≦ 7) → Dip at 25℃ × 20 – 30 min → Dry at 100 – 120℃→ Cure at 150 – 160℃ × 90 sec

-- Padding:                           10 – 40 g/L

Dyed fabrics (pH ≦ 7) → Twice dip & pad at 15 – 20℃ with water retention 70 – 80% → Dry at 100 – 120℃

-- Prepared solution should be used immediately while it appears translucent emulsion at approx. 25℃.

-- Specific process should be adjusted by testing.

 

Packing and storage

-- Packing:                           125 kg/polyethylene drum

-- Storage:                           6 months in cool and dry place with sealed packing
