Definitions

  • the process is carried out in an alkaline aqueous medium in the presence of reducing agents and, if appropriate, other customary auxiliaries at temperatures of, for example, 45 to 60 ° C., and the dyeings are then carried out finished by rinsing, oxidizing and soaping the textile material.
  • reducing agents which are used for vat dyeing of textile materials containing cellulose fibers are sodium dithionite, thiourea dioxide (formamidine sulfinic acid) and hydroxyacetone.
  • thiourea dioxide as a reducing agent in the vat dyeing of textiles containing cellulose fibers.
  • the reduction of the vat dyes can additionally be carried out in the presence of glucose in order to prevent sensitive dyes from being "over-reduced".
  • glucose based on the amount of thiourea dioxide, is used in a deficit. The levelness of the vat colorations that can be achieved with this is still in need of improvement.
  • the present invention has for its object to provide a process for dyeing textile materials consisting of cellulose fibers or containing cellulose fibers in a mixture with synthetic fibers in an alkaline aqueous medium with vat dyes in the presence of reducing agent mixtures and finishing the dyeings dyeings with better levelness are obtained than with known dyeing processes.
  • 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 flake, card sliver, yarn, skein, fabric or knitted fabric.
  • the cellulose fibers can either be natural or regenerated cellulose, such as cellulose or polynosic fibers.
  • the method according to the invention is particularly suitable for dyeing mercerized cotton, raw cotton and for dyeing raw yarns which are present as a package or as a strand.
  • Synthetic fibers which are present in the textile materials in a mixture with cellulose fibers are, for example, polyester fibers or synthetic polyamide fibers.
  • the fibers from natural or regenerated cellulose are dyed with vat dyes.
  • vat dyes are mainly anthraquinone and indigoid dyes.
  • Vat dyes have been commercially available for a long time and are documented in the Color Index, cf. Color Index, 3rd edition, 1971, volume 3, pages 3719-3844 and volume 4, C.I. 58000-74000, Society Dyers and Colorists, England.
  • sodium dithionite, thiourea dioxide or mixtures of sodium dithionite and thiourea dioxide are used in any ratio.
  • Sodium dithionite is preferably used as component a).
  • ⁇ -hydroxycarbonyl compounds are suitable as component b) of the reducing agent mixtures.
  • Suitable ⁇ -hydroxycarbonyl compounds are, for example, monohydroxyacetone (hereinafter referred to as hydroxyacetone), dihydroxyacetone, glycol aldehyde, dihydroxybutanone, 2,3-dihydroxyacrylaldehyde called as triose reductone, ascorbic acid and cyclopentendiol-2,3-one-1.
  • hydroxyacetone monohydroxyacetone
  • dihydroxyacetone glycol aldehyde
  • dihydroxybutanone 2,3-dihydroxyacrylaldehyde called as triose reductone
  • Compounds of this type are referred to as reductones and reductonates.
  • triose reductone and reducing acid which are obtained, for example, by acidic or alkaline degradation of glucose, saccharides or polysaccharides, such as starch, molasses and pectin. From this group of reducing agents, preference is given to hydroxyacetone. It is of course also possible to use mixtures of several ⁇ -hydroxycarbonyl compounds as component b) of the combinations to be used according to the invention, e.g. Mixtures of hydroxyacetone and glucose.
  • the textile material which contains the vat dye in the leuco form after the treatment in the dyebath is then treated in the customary manner in order to complete the dyeings.
  • the textile material is first oxidized according to methods used in vat dyeing. After the oxidation, the textile material is rinsed and soaped.
  • the dyeing can also be completed by first rinsing the textile material which contains the vat dye in the leuco form, then oxidizing it and then soaping it.
  • the process according to the invention can of course also be carried out in the presence of conventional leveling agents for vat dyeing, e.g. be carried out in the presence of polyvinylpyrrolidone or water-soluble polyamides, which are known, for example, from DE-PS 1 125 881.
  • polyvinylpyrrolidone or water-soluble polyamides which are known, for example, from DE-PS 1 125 881.
  • Copolymers of maleic acid and styrene, maleic acid and vinyl esters or maleic acid and vinyl ethers are also suitable.
  • the polymers in question have viscosities (measured using a Höppler falling ball viscometer at 20 ° C. in accordance with DIN 53 015) of 1 to 300 mPas in 7.5% by weight aqueous solution, which are brought to a pH value with sodium hydroxide solution 9 is set.
  • the use of such polymers in vat dyeing in amounts of 0.05 to 2% by weight, based on the material to be dyed, is known from DE-PS 2 444 823.
  • the advantages of the method according to the invention lie in an improved levelness of the textile materials containing dyed cellulose fiber. This applies in particular to those textile materials that are difficult to dye regardless, such as mercerized cotton, in particular mercerized cotton yarn in rope form or cotton yarn on particularly large packages (for example packages with more than 1200 g of yarn).
  • level dyeings in vat dyes or dye combinations of vat dyes are obtained, in which otherwise problems of levelness occur in the dyed materials.
  • Another advantage of the method according to the invention is that the wastewater pollution of the textile plant can be classified as lower than if sodium dithionite or thiourea dioxide are used alone.
  • a strand yarn made of mercerized raw cotton is first pre-wetted on a commercially available strand dyeing machine by treating the goods with 3 g / l of a phosphoric acid diethylhexyl ester as a wetting agent for 15 minutes at room temperature while constantly pumping around the dye bath in the dyeing machine.
  • the thus stranded yarn made of mercerized raw cotton is then dyed at a liquor ratio of 1:20 at 100 ° C. with a bath of the following composition: 1 part of the blue vat dye CI 69825 40 parts of aqueous sodium hydroxide solution 38 ° Bé 2 parts of sodium dithionite 4 parts of hydroxyacetone 1 part sodium polyacrylate (molecular weight 60,000) 952 parts of water
  • the bath is heated to 100 ° C within 30 minutes. It is dyed at 100 ° C. for 45 minutes, then cooled to 60 ° C. and the dyeing is completed as usual. A uniformly blue-colored strand yarn with good dyeing and very good fastness properties is obtained. The good levelness of the coloring within the strand and between different strands is clearly recognizable when knitting pieces are made from the yarn of one strand and from the yarn of different strands.
  • Raw cotton yarn is treated in a commercial cross-dyeing machine with an aqueous bath containing 3 g / l of diethylhexyl phosphoric acid as a wetting agent for 15 minutes at room temperature while continuously pumping around the aqueous medium.
  • the raw cotton yarn wetted in this way is then dyed at a liquor ratio of 1:15 with a bath of the following composition: 0.8 parts of the olive vat dye CI 69525 30 parts of aqueous sodium hydroxide solution 38 ° Bé 1 part sodium dithionite 4 parts of hydroxyacetone 1 part sodium polyacrylate with a viscosity of 35 mPas (30% aqueous solution at 20 ° C) 963.2 parts water
  • the liquor is pumped around at 60 ° C. for 10 minutes.
  • the liquor is then heated to 90 ° C. within 15 minutes with continuous pumping, and the fabric is dyed at 90 ° C. for 40 minutes.
  • the bath is then cooled to 60 ° C and the coloring is finished as usual, namely rinsing with water, oxidizing with 1 ml / l of hydrogen peroxide 40% and boiling soaps with a liquor containing 0.5 g / l of an adduct of 25 moles of ethylene oxide contains to 1 mole of a C12 / C18 fatty alcohol.
  • a uniformly olive-gray textile material with very good color and very good fastness properties was obtained.
  • the good levelness of the cheese package dyeing was clearly recognizable by the fact that knitted pieces were made in which the inner yarn layers and the outer yarn layers of a cheese package were knitted together. No differences in color and depth of color are found between the inner and outer yarn layers.
  • Ready-to-dye cotton woven goods were dyed on a conventional laboratory dyeing machine in closed bombs, which were moved throughout the dyeing process, with an aqueous liquor which contained the following constituents: 0.3% of the orange vat dye CI 69025 and 0.5% of the blue vat dye CI 59800 (based on the weight of the dry cotton weave), 30 ml / l aqueous sodium hydroxide solution (38 ° Bé) 0.3 g / l sodium dithionite and 3 g / l hydroxyacetone.
  • the liquor ratio was 1:20.
  • the liquor was heated to 60 ° C. At this temperature, only half of the material to be dyed in was added and the second half of the material to be dyed was added 5 minutes later. Both pieces of fabric were then dyed together while the bombs were moving continuously, by heating the liquor to 80 ° C. in the course of 10 minutes and then leaving it at 80 ° C. for 30 minutes.
  • the dyeing was then completed in the customary manner by rinsing the fabric with water, oxidizing with 1 ml / l of hydrogen peroxide and soaping at 95 to 100 ° C. with a commercially available rinse aid.
  • the two dyes 3 and 4 used for dyeing have a very different migratory capacity and draw up at different speeds. It was therefore not to be expected that the piece of fabric added later would have the same color depth and shade as the piece of fabric in the dye bath from the start. The example shows, however, that both pieces of fabric were dyed almost the same and thus good levelness was achieved.
  • Example 3 was repeated with the exception that the liquor now contained the following amounts instead of the amounts of sodium hydroxide solution, sodium dithionite and hydroxyacetone given in Example 3: 35 ml / l aqueous sodium hydroxide solution 38 ° Bé 0.5 g / l sodium dithionite and 3.5 g / l hydroxyacetone.
  • Example 3 The dyeing instructions given in Example 3 with dyes 3 and 4 were repeated with the exceptions that the aqueous dye liquor - as in the usual procedure according to the IN method - 12 ml / l aqueous sodium hydroxide solution 38 ° Bé and 3 g / l sodium dithionite as the sole Contained reducing agents. With this method of working you get clearly unevenly colored pieces of fabric. The piece of fabric added later was markedly lighter and less blue in color.
  • Example 3 The procedure given in Example 3 was repeated with the exception that the dye liquor contained 2.5 g / l sodium dithionite and 0.5 g / l hydroxyacetone. The amount of sodium hydroxide solution remained unchanged. This procedure resulted in two clearly unevenly colored pieces of tissue. The piece of fabric added later was markedly lighter and less blue in color.
  • Example 3 The procedure given in Example 3 was repeated with the exceptions that 20 ml / l aqueous sodium hydroxide solution 38 ° Bé, 2.5 g / l sodium dithionite and 2 g / l hydroxyacetone were used. In this case too, two clearly unevenly colored pieces of tissue were obtained, of which the piece of tissue added later was markedly lighter and less blue.
