description Introduction: In the present times, natural dyes become important for their safety, durability and environmental conservation. They give regional identity to any project of an artisanal nature where plants are used for dyeing. This paper studies the dyeing potential on merino wool fiber of native plants of the Patagonian steppe. M&M: The dyeing plant material collection area was limited to the southeast zone of Chubut, corresponding to the Floristic District of the Gulf San Jorge. The mother recipe was applied to obtain the dye and three types of procedures were developed: pre-mordant, direct mordant and post-mordant, depending on the moment of application of the alum. Sodium bicarbonate and iron sulfate colour modifiers were used. Using the universal table of the Munsell (Color, 2009) system, the tone, lightness and saturation were studied. Results: 50 native species of the Patagonian Region were studied. In its totality the following proportion was obtained: brown 37%, yellow 35%, olive 14%, gray 10%, pink 2% and green 2%. 9 species of higher chromatic saturation stand out. The most saturated colours are obtained during the pre-mordent process. The best represented families are Fabaceae and Asteraceae. Conclusions:  From the analysis of the literature on plants used for natural dyes in Argentina, it appears that numerous species studied in the present research have no antecedents and turn out to be promising, providing intense colours with high saturations. We can consider them true discoveries and suggest them with high dye potential for merino wool fiber.

Introducción: En los tiempos actuales los tintes naturales cobran importancia por su inocuidad, durabilidad y conservación ambiental. Otorgan identidad regional a todo proyecto de índole artesanal donde se empleen vegetales para teñir. El presente trabajo estudia el potencial tintóreo sobre fibra lana merino de las plantas autóctonas de la estepa patagónica.  M&M: El área de recolección del material vegetal tintóreo se circunscribió a la zona sureste del Chubut, Argentina, correspondiendo al Distrito Florístico del Golfo San Jorge. Se aplicó la receta madre para la obtención del tinte y se desarrollaron tres tipos de procedimientos, pre-mordentado, mordentado directo y post-mordentado, dependiendo del momento de aplicación del alumbre. Se emplearon modificadores de color bicarbonato de sodio y sulfato de hierro. Mediante el uso de la tabla universal del sistema Munsell (Color, 2009) se estudió el tono, la luminosidad y saturación. Resultados: Se estudiaron 50 especies nativas de la Región Patagónica. En su totalidad se obtuvo la siguiente proporción: marrones 37%, amarillo 35 %, olivas 14%, grises 10% rosados 2 % y verdes 2%. Se destacan 9 especies de mayor saturación cromática. Los colores con mayor saturación se obtienen durante el proceso pre-mordentado. Las familias mejor representadas son Fabaceae y Asteraceae. Conclusiones: Del análisis de la literatura de plantas empleadas para tintes naturales en Argentina, surge que numerosas especies estudiadas en la presente investigación no registran antecedentes y resultan ser prometedoras brindando colores intensos de saturaciones elevadas.  Podemos considerarlas verdaderos hallazgos y sugerirlas con alto potencial tintóreo para la fibra de lana merino.
