| 摘要 |
The invention describes a process for the preparation of granular dye formulations by mixing a (preferably water-soluble) dye, water, and optionally further assistants with a polyethylene glycol that melts in the range from 40 DEG to 150 DEG C., and drying the resultant solution or suspension in a spray drier or fluidized bed drier. The granular formulations so obtained are permanently dust-free, dissolve rapidly in an aqueous dyebath, and do not cause foaming during dyeing.
