The invention relates to a method for producing dyed textile materials consisting of polyester and polyamide. The textile material is dyed by means of pigments or a disperse dye that stains polyester. Surplus dye is removed. The polyamide portion is dyed using vat dyes, leuco vat dyes, sulphide dyes or soluble sulphide dyes. Said dyes are vatted if this is required for obtaining a solubility and are oxydatively converted into the real dyes after attaching.
