Definitions

  • the required amounts of the chlorinated alkylbenzenes of the formula (I) to be used according to the invention can easily be determined from case to case by preliminary search. In general, amounts of 1 to 7 g per liter of dyeing liquor have proven themselves in the usual liquor ratios of 1: 5 to 1:40, or 10 to 40 g per liter of padding liquor.
  • chlorinated alkyl benzenes to be used according to the invention are well compatible with other carriers, they can also be used in a mixture with known other carriers.
  • the chlorinated alkyl benzenes of the formula (I) to be used according to the invention are advantageously used together with anionic or nonionic emulsifiers or dispersants.
  • the disperse dyes used in the dyeing process according to the invention are the disperse dyes usually used for dyeing polyesters and cellulose esters, as described, for example, in "Color Index” Vol. 2, pp. 2483-2741, 3rd edition (1971).
  • the dyeing of the structures consisting of polyesters or cellulose esters and wool in the presence of the chlorinated alkylbenzenes to be used according to the invention is carried out by customary continuous or batch processes; The following may be mentioned as such: the customary process operating at 98 ° C., the high temperature and the thermosol process.
  • the isomer mixtures such as those obtained in the industrial chlorination of toluene, have been found to be particularly suitable.
  • Threads, fibers, fabrics, knitted fabrics, films and foils made of polyesters, such as polyterephthalic acid glycol esters, or polyesters made of 1,4-bis (hydroxymethyl) cyclohexane and terephthalic acid, and cellulose esters, e.g. Cellulose triacetate, with disperse dyes in deep shades and excellent to dye evenly.
  • polyesters such as polyterephthalic acid glycol esters, or polyesters made of 1,4-bis (hydroxymethyl) cyclohexane and terephthalic acid
  • cellulose esters e.g. Cellulose triacetate
  • Disperse dyes such as halobenzenes, alkyl phthalimides, aromatic carboxylic acid esters, methyl and methoxynaphthalenes, diphenyl, diphenyl ether, o-, m-up-oxydiphenyls or p-oxydiphenyl ethers.
  • halobenzenes alkyl phthalimides
  • aromatic carboxylic acid esters methyl and methoxynaphthalenes
  • diphenyl diphenyl ether
  • o-, m-up-oxydiphenyls or p-oxydiphenyl ethers o-, m-up-oxydiphenyls or p-oxydiphenyl ethers.
  • Diphenyl has good carrier properties, but it has the disadvantage of causing stains on the textiles because, due to its high melting point, it easily crystallizes out in the dyebaths and emulsifies poorly when the baths are heated.
  • Diphenyl ether has the disadvantage that its carrier activity depends strongly on the constitution of the disperse dye used, and therefore when dyeing with dye combinations, e.g. those for the production of gray and olive tones, no reproducible colorations can be obtained.
  • p-oxy-diphenyl has good carrier properties, it cannot be used as a carrier in the normal dyeing process at 98-100 ° C, since it is still solid at these temperatures. It also affects the lightfastness of the dyeings.
  • chlorinated alkylbenzenes to be used according to the invention have the advantages over these carriers mentioned. that they do not cause stains, that they do not adversely affect the lightfastness of the dyeings, that their effectiveness is independent of the dye constitution, that they can therefore be used to produce reproducible combination dyeings and that the odor nuisance is low.
  • the chlorinated alkyl benzenes have the advantage that they are effective even in lower concentrations. It should also be emphasized that they at least do not impair the build-up capacity of the disperse dyes, if not improve them, as do other carriers which retain the dyes in the dyebath. Another advantage is the excellent compensation for thread structure differences of heat-set polyester material.
  • a combination with 1,2,4-trichlorobenzene has proven to be particularly advantageous. While a pure trichlorobenzene setting already crystallizes at + 10 ° C to + 17 ° C, suitable combinations with dichlorotoluene result in freezing points down to - 20 ° C.
  • the compounds (I) to be used according to the invention are superior in terms of constitution to the closest chlorobenzene even that the wool portion is less soiled when dyeing the polyester portion of polyester-wool blended materials.
