Abstract

L'invention concerne la production sous la forme granulaire à faible teneur en poussière de colorants hydrosolubles. Le procédé consiste à ajouter à une pâte aqueuse de colorant avant son séchage par pulvérisation un agent tensio-actif anionique et un polymère hydrosoluble, les granules contenant 0,1 à 20 % en poids d'agent tensio-actif anionique et 0,1 à 4,0 % en poids de polymère hydrosoluble. Ce procédé s'adresse notamment à des colorants réactifs.The invention relates to the production in low dust granular form of water soluble dyes. The process involves adding to an aqueous dye paste before it is spray dried an anionic surfactant and a water soluble polymer, the granules containing 0.1 to 20% by weight of anionic surfactant and 0.1 to 4.0% by weight of water soluble polymer. This process is intended in particular for reactive dyes.
