|
|
: |
Clear pale yellow viscous liquid |
|
|
: |
Blend of Acrylic co-polymer, polycarboxylate and phosphonate
|
|
|
: |
Anionic |
|
|
: |
7 to 8 |
|
|
: |
Easily dilutable in cold water. |
|
|
|
: |
Good resistance of acids, alkalies and electrolytes
commonly used in Dyeing Process.
|
|
|
|
: |
Compatible with cationic mild alkaline conditions. |
| |
|
|
|
|
| |
|
|
DIQUEST SNA exhibits excellent dispersing effect on Raw Cotton impurities (Waxes & Pectinates) and on the precipitates caused due to hard water. DIQUEST SNA also has moderate chelating effect on metal ions. Consequently DIQUEST SNA eliminates the adverse effect of Calcium and Mg++ ions on the solubility of anionic dyes and their affinity to cellulosics. |
| |
|
|
 |
DIQUEST SNA has limited chelating potential, insufficient to remove metal ions form metal complex dye hence it does not impair the shade and fastness properties of Dyeing Process obtained with reactive and direct, metal complex dyes. |
| |
|
|
DIQUEST SNA is non foaming.
|
| |
|
|
Another factor in favour of DIQUEST SNA in this application is its moderate chelating effect. It thus suppresses the formation of calcium salts of reactive dyes hydrolysates that are difficult to wash out. |
|
| |
|
|
Thus DIQUEST SNA offers many advantages over strong, purely chelating agents based on EDTA and NTA. |
