|
|
: |
Good resistance of acids, alkalies and electrolytes
commonly used in Dyeing Process. |

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. |
| |
|
|
| 1. |
Dyeing Process Cotton with Vat Dyes : High concentrations of Ca+++ and Mg++ ions in grey cotton are responsible for substantial losses in colour yield obtainable using vat dyes. DIQUEST SNA by virtue of its chelating property prevents any colour yield losses in liquors of low to moderate hardness (150 mg Ca++/litr). (If water is of greater hardness then a stronger chelating agent will be necessary) like Ecosoft – 100. |
| |
|
| 2. |
Dyeing Process Cotton with Reactive & Direct Dyes :If the water is hard, calcium carbonates may be precipitated during the Dyeing Process of raw cotton with reactive and direct dyes. DIQUEST SNA is 1a very effective dispersant for the calcium carbonate thus formed and maintains it in a finely dispersed state. As a result, opalescence of the Dyeing Process liquor is avoided. |
| |
|
3. |
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. |
