Synthetic fibers and synthetic fiber textile materials finished with mineral oil finishes, silicone oil finishes or both can be simultaneously stripped of these finishes and dyed in one liquor comprising as essential ingredients a) anionic and/or amphoteric surfactants, b) dyes, and c) optionally further compounds selected from the group consisting of the nonionic surfactants, the terpene hydrocarbons/alcohols, sorbitol esters and their alkoxylates, fatty acid ethanolamides, alkylpolyglycosides and solvents. The treatment is carried out at pH 4.0 to 7.5 at 80-110°C and at a liquor ratio of 5:1 to 100:1.

Des fibres synthétiques et matériaux textiles, finis avec une huile minérale, une huile de silicone ou les deux, peuvent être débarrassés de leurs finis et teints dans une seule liqueur renfermant comme ingrédients essentiels : a) des surfactifs anioniques et (ou) amphotères; b) des colorants; c) d'autres composés facultatifs, choisis dans le groupe constitué de tensioactifs non ioniques, d'hydrocarbures/alcools terpéniques, d'esters de sorbitol et de leurs alcoxylats, d'éthanolamides d'acides gras, d'alkylpolyglycosides et de solvants. Le traitement est appliqué à un pH de 4,0 à 7,5, à 80-110 degrés C, et à un rapport de solution de 5:1 à 100:1.
