The Effects of Natural Bicarbonate in Waters on the Dying of Cotton with Reactive Dyestuffs and Solutions study was carried out in the XV. It was presented by Reşat UCA at the NATIONAL CHEMISTRY CONGRESS.

Published Summary,
Natural bicarbonate causes pH changes in cotton dyeing processes with reactive dyestuffs. For this reason, pH stability cannot be achieved before and after soda in dyeing. While pre-soda pH rises early due to bicarbonate, it cannot reach pH = 11 after soda and decreases towards 8.82 during the process. In this study, the cause of the pH problem and the solution alternatives for these problems were tried and compared in laboratory and operating conditions.
Method
The bicarbonate amount of this water was determined by taking the operating water containing high amount of bicarbonate. Controlled staining was done with this water. Bicarbonate was removed from the water with alternative solutions and repainted.
Conclusion
The bicarbonate problem can be easily avoided by using Colinor AB. pH stability is ensured in dyeing. In general, there is an increase in the dyeing efficiency of all dyestuffs.
