Abstract

La présente invention concerne des compositions nouvelles et non évidentes, et des procédés convenant à la teinture de fibres naturelles avec des pigments naturels qui garantissent une égalité de ton. La présente invention concerne donc des compositions et des procédés de teinture de fibres naturelles (fils, tissus et vêtements) à l'aide de colorants naturels, permettant une égalité de ton et de nuance dans le même lot et entre des lots différents. Selon l'invention, l'utilisation d'une solution de sulfate de fer aux concentrations décrites, et l'utilisation des procédés décrits, en même temps que l'utilisation de pelotes de fil lâchement bobinées permet une pénétration améliorée du colorant (absorption) dans la pelote de fil, permettant ainsi une teinture uniforme de la pelote.
