Abstract

Procédé pour obtenir des particules de colorant qui résistent à l'abrasion et n'engendrent pas de poussière, ce colorant étant soluble dans l'eau. On pulvérise, par la buse 2, une solution aqueuse de colorant dans un lit tourbillonnaire de particules de colorant qui est produit par un courant gazeux, arrivant par 4, capable d'absorber l'humidité.Process for obtaining dye particles which resist abrasion and do not generate dust, this dye being soluble in water. An aqueous solution of dye is sprayed through nozzle 2 into a swirling bed of dye particles which is produced by a gas stream, arriving at 4, capable of absorbing moisture.
