Definitions
- the invention relates to a process for dyeing and printing textile materials which consist of cellulose fibers or contain cellulose fibers in a mixture with other fibers in an aqueous medium at pH values above 12 with viable dyes in the presence of at least one Reducing agent for the viable dyes and finishing the coloring in the usual way.
- EP-A-0 364 752 discloses a process for dyeing cellulose fiber textile materials with vat dyes in an alkaline medium, in which mixtures of sodium dithionite and / or thiourea dioxide and ⁇ -hydroxycarbonyl compounds, such as hydroxyacetone, are used as reducing agents , begins and the coloring
- the object of the present invention is to provide a reducing agent for the process described at the outset which is stable in the strongly alkaline dye liquor, i.e. do not condense to colored products under dyeing conditions and if possible cause no odor problems.
- the object is achieved according to the invention with a process for dyeing and printing textile materials made from cellulose
- 40 fibers consist of or contain cellulose fibers in a mixture with other fibers, in an aqueous medium at pH values above 12 with viable dyes in the presence of at least one reducing agent for the viable dyes and completion of the dyeing in the usual way if a reducing agent is used cycli-
- the textile materials consist of cellulose fibers or contain cellulose fibers in a mixture with other fibers. They can be in any processing state, e.g. as a flake, card sliver, yarn, skein, fabric or knitted fabric.
- the cellulose fibers can either be natural or regenerated cellulose, such as rayon, viscose or polynosic fibers. Both mercerized cotton and raw cotton as well as raw yarn, which is present as a package or as a skein, can be dyed by the process according to the invention.
- Synthetic fibers which are present in the textile materials in a mixture with cellulose fibers are, for example, polyester fibers, polyacrylonitrile fibers or synthetic polyamide fibers.
- the cellulose fibers are dyed with viable dyes, such as vat dyes, in particular indigo, or sulfur dyes.
- viable dyes such as vat dyes, in particular indigo, or sulfur dyes.
- the vat dyes are either In ⁇ digo or anthraquinone or indigoid dyes.
- Vat dyes and sulfur dyes have long been commercially available and documented in the Color Index (C.I.), cf. Color Index, 3rd edition 1971, volume 3, pages 3719 to 3844, and volume 4, C.I. ⁇ No. 58000 to 74000, Soc. Dyers and Colorists, England.
- the combinable dyes are used in the process according to the invention in the amounts customarily used for dyeing, for example in the range from 0.01 to 10% by weight, based on the textile material.
- a single dye or a mixture of 2 or more combinable dyes can be used here.
- the dyeing of the textile materials can be carried out using the exhaust process, for example from a long aqueous liquor at a liquor ratio of 1: 5 to 1:40, preferably 1: 8 to 1:20. or also in the continuous process, for example block-steaming process.
- liquor ratios of 1: 0.5 to 1: 3 and correspondingly higher concentrations of reducing agent and sodium hydroxide solution are used, usually 10 to 100 g / 1 at least one reducing agent and 50 to 200 g / 1 NaOH 38 ° Be ⁇ used.
- Printing on textile materials is also possible using the method according to the invention.
- the pH of the aqueous liquors is above 12. It is adjusted by adding alkali metal hydroxides to the aqueous dyeing medium. Suitable alkali metal hydroxides are sodium hydroxide and potassium hydroxide, preference being given to the use of sodium hydroxide solution as alkali metal hydroxide.
- the concentration of the alkali metal hydroxide in the aqueous dye liquor is usually 10 to 500, preferably 30 to 250 ml of aqueous alkali metal solution at 38 ° B ⁇ / l liquor.
- cyclic compounds according to the invention are used as reducing agents which have the structural unit at least once
- Suitable compounds with the structural unit (I) in the ring of the molecule are the following compounds:
- n 1 or 2
- substituents R 1 , R 2 and R 3 independently of one another are H, C 1 -C 4 -alkyl, OH, OCH 3 or phenyl, for example the compounds Va-Vc:
- R 1 , R 2 and R 3 independently of one another denote H, C 1 -C 4 -alkyl, OH or OCH 3 , for example the compounds Vla-VIc:
- cyclic ⁇ -hydroxyketones with the structural units I indicated above ⁇ -hydroxycyclohexanone and / or ⁇ -hydroxycyclopentanone are preferably used.
- the cyclic ⁇ -hydroxyketones with the structural unit I are used in amounts of 0.5 to 10, preferably 1 to 6 g / 1.
- quinoid compounds which are water-soluble at pH values above 12. These compounds are dissolved in the aqueous liquor under the dyeing conditions. Suitable quinoid compounds which are suitable for this purpose are known from DE-B-2 164 463.
- Quinoid compounds are, for example, derivatives of benzoquinone, naphthoquinone, acenaphthenquinones or anthraquinones, such as hydroxyanthraquinones, for example 2-hydroxyanthraquinone and 1,4-di-hydroxyanthraquinone, anthraquinonecarboxylic acids, anthraquinone carboxylic acids, and such as anthraquinone-2-sulfonic acid and 1,4-diaminoanthraquinone-2-sulfonic acid. These connections are called accelerators common in vat dyeing.
- the quinoid compounds are used in amounts of 1 to 10% by weight, based on the amount of the dye used.
- the cyclic ⁇ -hydroxyketones with structure I can optionally be used with all reducing agents known for dyeing vat dyes, e.g. in a mixture with sodium dithionite and / or thiourea dioxide.
- the weight ratio of the cyclic ⁇ -hydroxyketones to be used according to the invention to sodium dithionite and / or thiourea dioxide in such reducing agent mixtures is, for example, 1: 1 to 1:15, preferably 1: 2 to 1:10.
- the alkaline-aqueous dyeing liquor can optionally also contain polymers of monoethylenically unsaturated carboxylic acids as dyeing aids.
- dyeing aids are known, for example, from DE-B-2 444 823. These are essentially homopolymers and copolymers of monoethylenically unsaturated carboxylic acids.
- the copolymers contain at least 10% by weight of a monoethylenically unsaturated carboxylic acid copolymerized.
- Individual compounds of this type are, for example, polyacrylic acid, polymethacrylic acid, copolymers of acrylic acid or methacrylic acid with other monomers, e.g. Methacrylamide, acrylamide, acrylonitrile, methacrylonitrile, acrylic acid esters, methacrylic acid esters. Also suitable are copolymers of acrylic acid and maleic acid, copolymers of acrylic acid and itaconic acid, copolymers of maleic acid and vinyl star, copolymers of maleic acid and vinyl ethers. It is only essential that the copolymers contain at least 10, preferably at least 50 mol% of a monoethylenically unsaturated carboxylic acid in copolymerized form.
- the copolymers can be used as coloring aids in the form of the free acids or preferably in a form already neutralized with alkaline solutions.
- the K values of the homo- and copolymers of monoethylenically unsaturated carboxylic acids are from 15 to 90 and are preferably in the range from 20 to 65.
- the K values are determined according to H. Fikentscher, Cellulosechemie, Volume 13, 58-64 and 71-74 (1932) in aqueous solution at a temperature of 25 ° C. and a concentration of 1% by weight at pH 7 on the sodium salt of the polymers.
- the polymers are used in amounts of 0.05 to 2% by weight, based on the textile materials to be dyed.
- the dyeing is carried out in the temperature range in which vat dyeings with reducing agents are usually carried out, for example from 20 to 130, preferably 40 to 115 ° C.
- the usual pressure equipment such as HT equipment, jet dyeing machines, etc. are used, depending on the design of the textile material.
- the textile material which after the treatment in the dyebath contains the linked dye in the leuco form, is treated in the usual way to complete the dyeings.
- the textile material is first oxidized according to the methods used in the vat dyeing, e.g. Dwell in the air of the material containing the leuco dye or treatment of this material with an aqueous liquor which contains hydrogen peroxide or another oxidizing agent. After the oxidation, the dyed textile material is rinsed and soaped.
- the dyeing can, however, also be carried out in such a way that the textile material which contains the vat dye in the leuco form is first rinsed, then oxidized and then soaped.
