Definitions

  • the present invention relates to a process for the uniform dyeing of piece goods from mixtures of cellulose fibers with synthetic polyamide fibers and possibly elastomer fibers based on polyurethane by a pad-steaming process.
  • the invention is therefore based on the object of developing a simple block dyeing process for mixtures of cellulose fibers and synthetic polyamide fibers using sulfur dyes.
  • piece goods made from mixtures of cellulose fibers with synthetic polyamide fibers and, if appropriate, elastomer fibers based on polyurethane can be dyed uniformly using a pad-damping process by using aqueous pad liquors which contain sulfur dyes, alkaline reducing agents and selected metal complex and / or acid dyes , blocks on the textile material mentioned and fixes the dyes by steaming at 100 to 110 ° C within 30 seconds to 10 minutes.
  • the reducing agents used are the agents customarily used in the dyeing of sulfur dyes, such as sodium sulfide or sodium hydrogen sulfide / soda, either alone or as a mixture.
  • a supplementary addition of a sodium polysulfide of the formula Na 2 S 2-5 to the above-mentioned reducing agents has proven to be advantageous for stabilizing the reduction conditions.
  • glucose / sodium hydroxide solution can be used as a reducing agent, and if the sulfur dyes are suitable for dyeing with hydrosulfite, hydrosulfite (sodium dithionite) / alkali can also be used.
  • the method according to the invention thus allows the fiber mixtures mentioned to be dyed with the required high level of fastness while maintaining all dyeing advantages, such as single-bath, economical dyeing with little expenditure of time and a reduced amount of waste water.
  • Suitable sulfur dyes are all sulfur dyes, including leucosulfur dyes and the water-solubilized sulfur dyes listed in the COLOR INDEX as "Solubilized Sulfur Dyes".
  • Suitable dyes are now those whose coloration B on the synthetic polyamide fiber does not deviate in color from coloration A and whose color depth does not appear to be more than 10% lighter than coloration A.
  • the cotton strand should also be stained as little as possible. If a dye tested in this way proves to be resistant to the effects of the chemicals under these conditions, then it will remain so even after prolonged exposure.
  • Selected metal complex dyes can also be used in a mixture with selected acid dyes.
  • the process according to the invention can be used to dye mixtures of cellulose fibers and synthetic polyamide fibers in virtually all mixing ratios on the dyeing machines suitable for this.
  • the further treatment after steaming is carried out in the usual way by rinsing, reoxidizing, rinsing and soaps, as is usually the case with sulfur dyes.
  • the effective energy flux through the cone defined by the orbiting arc is increased, since the energy flux ⁇ , at a cross-section of the cone having diameter 2r, is given by the equation: whereas, when the cone contains large amounts of entrained particles, the effective energy flux becomes and hence ⁇ 2 > ⁇ 1 .
  • the dye is fixed by steaming for two minutes at 102 ° C without drying.
  • the further treatment is carried out as with conventional dyeings with sulfur dyes by reoxidation, rinsing and soaps. An even, full olive color is obtained on all fiber components in the clay.
