PROCESS FOR THE SPRAY-DRYING OF DYES AND OPTICAL BRIGHTENERS EASILY SOLUBLE IN WATER |
摘要 |
<p>A process is described for spray-drying readily water-soluble dyes and fluorescent brighteners from a saturated aqueous solution which contains undissolved dye or fluorescent brightener in a ratio between dissolved and undissolved matter of 1:9 to 9:1. The free-flowing dye or brightener granulates obtained in this process are distinguished by high bulk density, abrasion resistance and dimensional stability.</p> |
