| (Non – Formaldehyde Type Fixing Agent for Reactive Dyeing & Printing) |
| Iwa Fix is a fixing agent to improve the wet fastness of reactive and direct dyeing and printing of cellulosic fibers. Iwa Fix is also applicable to after-mercerized dyeing. |
| COMPOSITION : |
| The aqueous solution of cationic polymers (POLYDIALLYLAMINE TYPE). |
| PROPERTIES : |
| - Light yellow clear solution |
|
| - Specific gravity = 1.04 (25°C) |
|
| - pH (10 g/l) = 4 |
|
| - Easily can be diluted with cold water in every ratio |
|
| CHARACTERISTICS : |
| - Improves the fastness to water, wishing, acid-hydrolysis and chlorinated water. |
| - Only slight influence on the hue of dyeing. |
| - No or only slight influence on the light fastness. |
|
- No or only slight influence on the handling touch.
|
| - High resistance to acids, alkaline and hard water |
| - Contains no formaldehyde. |
| - Compatible with many softening and finishing agents provided that they are not anionic. |
| |
| APPLICATION : |
| The dyed, well rinsed material is treated as follows |
| Exhaustion method |
Continuous method |
| Iwa Fix = 2 ~ 6 % o.w.f. |
Pad the dyeing with 5 ~ 30 g/l |
| Ligqor ratio = 15: 1 ~ 20: 1 |
Solution of Iwa Fix at |
| Temperature = 40 ~ 60 °C |
20 ~ 40º C then squeeze and dry. |
| Duration = 15 ~ 20 min |
|
| CAUTIONS IN USING : |
| - Insufficient rinsing before fixing treatment can impair fastness properties. |
| - Avoid the mixing with anionic substances. (Precipitation may occur.) |
| - The stripping of Iwa Fix is highly difficult. |
