摘要： Described is a process for the dyeing of textile material by the exhaust method, whereby the dyeing is commenced at a pH value of between 6 and 12 and terminated at a pH value of between 3 and 7, which process is characterized in that during dyeing the pH value is lowered, by the addition of an inorganic acid, by at least 1 unit of pH value; and that subsequent to the dyeing the exhausted bath, after the addition of alkali, dye and, if required, further auxiliaries, is optionally used afresh for dyeing.Furthermore an apparatus for carrying out this process is described which consists of a dyeing aggregate having a liquor-circulating system which contains at least one pH-measuring point as well as at least one dosing device.

摘要： The invention relates to a process for dyeing synthetic polyamide fibre material with dyes or dye mixtures in the presence of a mixture of dyeing assistants, which comprises using for the dyeing of these materials an aqueous liquor which contains at least one anionic dye which, under the defined dyeing conditions, has a degree of exhaustion of at least 95% at 1/1 standard depth of shade, and a dyeing assistant mixture containing an anionic compound, a quaternary compound and a non-ionic compound, and wherein the liquor contains an alkali metal salt and an organic acid, and finishing the dyeing at pH 5-7, preferably pH 5.5-6, and at a temperature of 95.degree. to 130.degree. C.The process according to the invention is suitable for dyeing synthetic polyamide materials, producing level dyeings having good fastness properties with all types of dye or mixtures of dyes of identical or different types.

摘要： The invention relates to a process for the non-skittery and level dyeing of fibre material made of natural polyamides, with dyes or mixtures of dyes in the presence of a mixture of dyeing assistants, which comprises using for dyeing these materials an aqueous liquor which contains at least one anionic wool dye which, under the defined dyeing conditions at 1/1 standard depth, exhausts to at least 95%, and a dyeing assistant mixture containing an anionic compound of the formula ##STR1## in which R is an alkyl or alkenyl radical having 12 to 22 carbon atoms, M is hydrogen, an alkali metal or ammonium, and m and n are integers such that the sum of m and n is 2 to 14, a quaternary compound of the formula ##STR2## in which R', independently of R, is what R has been defined as, A is an anion, Q is a substituted or unsubstituted alkyl radical, and p and q are integers such that the sum of p and q is 20 to 50 , and a non-ionic compound of the formula ##STR3## in which R", independently of R, is what R has been defined as, and x and y are integers such that the sum of x and y is 80 to 140, and which liquor can, if desired, also contain an ammonium or alkali metal salt, and finishing the dyeing regardless of its depth at pH 4.5-5.5 and at a temperature of 95.degree. to 105.degree. C. The process according to the invention is suitable for dyeing natural polyamide materials, especially wool, but also wool/nylon, wool/polyester, wool/cellulose or wool/polyacrylonitrile blends and silk, giving, with various types of dye or mixtures of dyes of identical or different dye types, non-skittery and level dyeings having good fastness properties.
