Definitions

  • the present invention relates to a process for the aftertreatment of cellulose material dyed with sulfo-containing reactive dyes.
  • Anionic direct or reactive dyes which contain sulfo groups are usually used for dyeing cellulose material. If the dyeing and the subsequent treatment steps or at least the last step before drying take place in the neutral or basic range, the wet fastness of the dyeings corresponds to the expectations and the tensile strength of the cellulose material is not impaired.
  • the cellulose material is, however, in some cases still rinsed with deionized water or treated in a bath with a pH below 7, e.g. when rinsing with process water that is acidic, or if there is a post-treatment at acidic pH values or a dyeing of any accompanying tissue at acidic pH values.
  • a deterioration in the wet fastness of the dyeing and / or a reduction in the tear resistance of the cellulose material often occurs.
  • the present invention thus relates to a process for the aftertreatment of cellulose material which has been dyed with sulfo-containing dyes and which has been treated with deionized water after the dyeing or has been treated at an acidic pH during or after the dyeing, characterized in that the reactive dye is used which contains sulfo groups dyed cellulose material before drying with an aqueous solution of an alkali or alkaline earth metal salt aftertreated at a temperature between 5 and 50 ° C.
  • the aftertreatment preferably consists in rinsing the colored cellulose material with an aqueous liquor which contains a neutral or weakly basic alkali metal or alkaline earth metal salt of an inorganic or organic acid.
  • These salts are primarily water-soluble salts, for example the lithium, sodium, potassium, magnesium, calcium or barium salts of monovalent or polyvalent inorganic or organic acids, such as hydrochloric acid, hydrobromic acid, hydrofluoric acid, nitric acid, sulfuric acid , Phosphoric acid, carbonic acid, formic acid or acetic acid.
  • Such metal salts include e.g. Consider: sodium nitrate, potassium nitrate, calcium nitrate, magnesium nitrate, sodium chloride, potassium chloride, calcium chloride, magnesium chloride, calcium acetate, sodium and potassium monophosphate, sodium, potassium and magnesium sulfate as well as sodium or potassium bicarbonate.
  • a sodium, potassium or calcium salt of hydrochloric acid, sulfuric acid or acetic acid is preferably used, and sodium or potassium chloride or sulfate are particularly preferred.
  • salts are preferably used as aqueous solutions containing 0.1 to 10% by weight, in particular 0.5 to 5% by weight, of salt.
  • the colored cellulose material is expediently rinsed with the liquor containing the alkali metal or alkaline earth metal salt immediately before drying, for example at a liquor ratio of 1: 5 to 1: 100, preferably 1:10 to 1:50, the temperature being between 5 and 50 ° C, preferably between 10 and 30 ° C.
  • the treatment time is preferably about 1 to 60 minutes, in particular about 5 to 30 minutes.
  • Suitable cellulose material for the process is textile material made of cellulose fibers or mixtures thereof with synthetic fibers, cellulose fibers being those made from natural and regenerated cellulose, such as e.g. Hemp, linen, jute, viscose silk, rayon or especially cotton.
  • fiber materials made of synthetic polyamide such as condensation products from hexamethylenediamine and adipic acid (polyamide 6.6) or sebacic acid (polyamide 6.10), furthermore mixed condensation products e.g. from hexamethylenediamine, adipic acid and ⁇ -caprolactam (polyamide 6,6 / 6), also polymerization products from s-caprolactam or from ro-aminoundecanoic acid.
  • Polyester material can also be used, e.g.
  • linear high molecular esters of aromatic polycarboxylic acids with polyfunctional alcohols for example those made of terephthalic acid and ethylene glycol or dimethylolcyclohexane, and also copolymers of terephthalic acid and isophthalic acid and ethylene glycol.
  • cellulose (2 1/2) acetate and cellulose triacetate fibers are also suitable as synthetic fibers.
  • the textile material can e.g. as woven, knitted fabric, e.g. Knitwear or knitted fabric, or as a fleece.
  • This cellulose material is first dyed in the customary manner, dyes which have 1 to 6, preferably two to four, sulfo groups being suitable.
  • the dyes can belong to any class. These are, for example, sulfo-containing dyes of azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, Thioxanthone, nitroaryl, naphthoquinone or pyrenchinone series, preferably around anthraquinone, phthalocyanine or formazane and in particular azo dyes.
  • dyes are also to be understood as meaning optical brighteners.
  • Brighteners of the following classes of compounds in question stilbenes, coumarins, benzocoumarins, pyrenes, pyrazines, pyrazolines, oxazines, mono- or dibenzoxazoyl or imidazolyl compounds, aryltriazole and v-triazole derivatives and naphthalic acid imides.
  • Azo or anthraquinone dyes with two to four sulfo groups are particularly suitable.
  • These dyes contain at least one reactive group, i.e. a group which under dyeing conditions reacts with the textile material to form a covalent bond.
  • reactive groups are, for example: aliphatic reactive radicals, such as the acryloyl, vinylsulfonyl, ⁇ -sulfatoethylaminosulfonyl, haloacryloyl, halogenopropionyl or haloacetyl radicals, where halogen is fluorine or, in particular, bromine or chlorine, or heterocyclic reactive radicals, e.g.
  • the aftertreatment according to the invention has a particularly advantageous effect on dyeings with reactive dyes of the triazine, vinylsulfone or pyrimidine series.
  • the dyeings with reactive dyes are usually carried out in an alkaline medium, but often a further treatment follows, which requires an acidic pH, so that the process according to the invention often has advantages even when dyeing with such dyes.
  • the cellulose material is optionally rinsed with water and then dried in the customary manner.
  • the colored cellulose material obtained has an unchanged tear strength compared to the uncolored cellulose material and the wet fastness properties of the dyeings are just as good as for dyeings which were not treated in an acid bath.
  • Example 1 of US Pat. No. 3,738,800 relates to dyeing polyester / cotton material with direct dyes in the acidic range with dyeing the polyester portion at 250-255 ° F with the addition of NaCl. A normal washing process follows the coloring. This example 1 therefore gives no indication of an improvement in fastness properties by means of an aftertreatment.
  • Example 5 of DE-A-2 338 816 the aqueous solution of sodium carbonate is added for the purpose of rinsing at a temperature of 60 ° C. and not after-treatment.
  • An aqueous padding liquor is prepared, containing 40 g of the dye of the formula per liter 48 ml water glass (38 ° Be) and 14 ml 30% sodium hydroxide solution.
  • a cotton fabric is padded with the liquor obtained, so that it increases by 70% of its weight, and then docked at the same edge.
  • the cotton fabric is stored for 3 hours at room temperature.
  • the dyeing is then rinsed with water, containing 4 ml of 60% acetic acid per liter and then with a 1% NaCl solution in a 1:40 liquor ratio for 10 minutes. Finally, it is dried at 180 ° for 1 minute. A red color is obtained with very good wet fastness properties. The tensile strength of the fabric is the same as for the undyed fabric.
  • Example 2 2 parts of the reactive dye used in Example 1 are dissolved in 2000 parts of water. This dye bath is mixed with 100 parts of a blend of polyamide 6.6 and cotton (50:50) at 40 ° . After 5 minutes, 30 g of NaCl and, after a further 40 minutes, 2 g of calcined soda and 4 ml of 30% sodium hydroxide solution are added, and the mixture is colored for a further 90 minutes at 40 °.
  • the dyed goods are rinsed twice with water and then go into 2000 parts of an aqueous liquor at 40 ° which has been adjusted to a pH of 4.5 to 5.5 with acetic acid.
  • 0.45 part of the dye of the formula is used and 0.01 part of the dye of the formula and heats up to boiling temperature within 30 minutes. It is dyed for 45 minutes at this temperature, then cooled to 60 ° within 15 minutes and rinsed first with water, then with a 0.5% NaCl solution and then again with water. Then it is dried for 1 minute at 180 ° .
  • a tone-in-tone red-colored mixed fabric is obtained which has very good wet fastness properties. The tensile strength is the same as for the undyed fabric.
  • An aqueous padding liquor is prepared, containing 40 g of the dye of the formula per liter 95 ml water glass (38 ° Be) and 28 ml 30% sodium hydroxide solution.
  • a cotton fabric is padded with the liquor obtained, so that it increases by 70% of its weight, and then docked at the same edge.
  • the cotton fabric is stored for 8 hours at room temperature.
  • the dyeing is then rinsed with water, containing 4 ml of 60% acetic acid per liter and then with a 1% NaCl solution in a 1:40 liquor ratio for 10 minutes. Finally, it is dried at 180 ° C. for 1 minute. A red color is obtained with very good wet fastness properties.
  • a cotton fabric is padded with the liquor obtained, so that it increases by 70% of its weight, and then docked at the same edge.
  • the cotton fabric is stored for 6 hours at room temperature.
  • the dyeing is then rinsed with water, containing 4 ml of 60% acetic acid per liter and then with a 1% NaCl solution in a 1:40 liquor ratio for 10 minutes. Finally, it is dried at 180 ° C. for 1 minute.
  • the scarlet color obtained has very good wet fastness properties.
