Abstract

Abstract Translated from French L'invention a trait à la chimie des colorants. Elle concerne des préparations dont les colorants n'ont pas tendance à cristalliser dans le bain de teinture et dont les eaux résiduaires sont aisément biodégradables; on obtient aisément de telles préparations en utilisant des colorants organophiles dont les points de fusion sont inférieurs à 140 degrés C et de préférence inférieurs à 100 degrés C, et on mélange ces colorants jusqu'à consistance homogène, sans opération coûteuse de division en fines particules, avec des composés émulsionnants polaires/apolaires tels que des sulfates et sulfonates gras. Application à la teinture de polyesters et de polyamides. The invention relates to the chemistry of dyes. It relates to preparations whose dyes do not tend to crystallize in the dye bath and whose waste water is easily biodegradable; such preparations are readily obtained by using organophilic dyes whose melting points are less than 140 degrees C and preferably less than 100 degrees C, and these dyes are mixed until a homogeneous consistency, without an expensive operation of dividing into fine particles , with polar / non-polar emulsifying compounds such as fatty sulfates and sulfonates. Application to the dyeing of polyesters and polyamides.
