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 *- 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:
**4% (O.W.F) Bath
ratio:
1: *0 – *0 Dyed fabrics
(pH≦7) → Dip
at*5℃× *0 – *0 min → Dry at **0
–**0℃→ Cure at **0 –**0℃× *0 sec *-
Padding:
*0 – *0 g/L Dyed fabrics
(pH≦7) → Twice dip & pad
at *5 –*0℃with water retention
*0–*0%→ Dry at **0 –**0℃ *- Prepared solution should be used
immediately while it appears translucent emulsion at approx.
