Definitions

• the invention relates to a process for dyeing textiles consisting of or containing cellulose fibers with reactive dyes with an anionically removable reactive group after the exhaust process from aqueous electrolyte-containing dye baths, characterized in that in the acidic range in the presence of acid acceptors, in particular buffer substances at 90 - 130 ° C colors.
• the process is carried out in particular as a one-bath, one-step process and can therefore be used, for example, on high-temperature packers and cross-winder units, jet dyeing machines, reel runners and jiggers.
• Suitable buffer substances are, for example, mono-, di- and trisodium phosphate, sodium bisulfate, sodium acetate / acetic acid and others, which are described in large numbers in the literature.
• the electrolyte-containing dyebath is adjusted to pH 4.5-5 at 25-80 ° C with sulfuric acid, acetic acid, phosphoric acid or sodium bisulfate.
• the textile material is introduced and then 0.1-10 g / 1 mono-, di- or trisodium phosphate, borax or sodium acetate are added until a pH of about 6-6.5 is established. Then dye is added and dyed.
• the dyebath is first adjusted to pH 4.5-5 with 0.1-2 g / 1 sodium bisulfate and / or monosodium phosphate, and di- or trisodium phosphate is added continuously during the dyeing process to achieve a pH value of around 6-6.5.
• the dye baths preferably contain 30-120 g / l of electrolyte, especially sodium sulfate.
• the process is of particular interest for the single-bath, single-stage dyeing of cellulose-polyester or polyamide or polyacrylonitrile mixtures with mixtures of reactive and disperse or acid or cationic dyes.
• both types of fibers can also be dyed with the reactive dyes tone-on-tone.
• the method is suitable in principle for all cellulose reactive dyes with an anionically removable reactive group, which are described in large numbers. It is very particularly suitable for dyes with dichlorotriazinyl, monochlorotriazinyl, monofluorotriazinyl, fluoropyrimidinyl, dichloroquinoxalinyl, methylsulfonylpyrimidinyl and vinylsulfonyl or sulfatoethylsulfonyl reactive groups.
• customary auxiliaries for example basic leveling agents such as are used in dyeing wool or polyacrylonitrile, can be added to the dye baths.
• the flow through the winding body is 8 minutes from the inside out and 8 minutes from the outside in.
• the resulting pH is between 4.5 and 5.
• the liquor is then heated to 110 ° C. in 25 minutes and the amount of 2.25 parts of trisodium phosphate dissolved in the batch vessel is slowly pumped in by means of an additional pump for 2 hours, so that sets a pH of 6.2 - 6.8 in the dyeing liquor and is maintained throughout the dyeing process.
• the resulting pH is 6.2.
• the dyebath is brought to 125 ° and kept at this temperature for two hours with good liquor circulation.
