Abstract
Procedimiento para la obtención de composiciones de colorantes o aclaradores ópticos pobres en polvillo, esencialmente por secado mediante pulverización de una suspensión acuosa que contiene el colorante o el aclarador óptico soluble en agua y eventualmente otros aditivos, caracterizado porque comprende, en una primera fase tratar en suspensión acuosa el producto, colorante o aclarador óptico, con una proporción del 5% a lo menos, preferentemente del 10 al 50% en peso y en particular el 30%, en peso, respecto al producto final seco resultante del ,proceso, de un fijador que contiene preferentemente 5 grupos de hidroxilo a lo menos por molécula y, seguidamente ajustar el pH de la suspensión resultante a valores comprendidos entre 4 y 7,5, en función al tipo de colorante o aclarador óptico en tratamiento por acción de una solución básica y, eventualmente, un tampón; secarse, en una segunda fase del proceso, por pulverización, la suspensión acuosa antes formada y, a continuación, la suspensiónacuosa y/o el producto secado tratarlo por pulverización con 1 al 15% en peso, particularmente del 5 al 10% en peso, respecto al producto final seco resultante del proceso, de un aglutinante tensioactivo no ionógeno verificándose el tratamiento con el aglutinante, si éste se añade al producto secado por pulverización, preferentemente por rociadura o aspersión del aglutinante calentado a 5Oº-100ºC sobre el producto secado por pulverización, calentado a su vez aproximadamente a 60º-85ºC.
