Definitions

  • aromatic carboxylic acid esters 2. chlorinated aromatic hydrocarbons 3. phenol derivatives and diphenyl, and
  • naphthalene derivatives The carrier substances of groups (1) and (2), for example benzoic acid methyl ester, salicy-lic acid methyl ester, mono-, diand trichlorobenzenes or -toluenes and similar compounds do not affect the fastness to light of the dyeings or may be removed from the fiber by a simple treatment, for example, by drying in the air or at temperatures which are usual in the industry, or lower.
  • the carriers of groups (3) and (4) are mainly composed on the basis of o-phenylphenol or its alkali metal salts, diphenyl and methylnaphthalenes.
  • the diphenyl shows the best reaction.
  • a light heat treatment for example at drying temperatures which are usual in the industry, the diphenyl remaining in the fiber during the dyeing process can be eliminated to such an extent that a yellowing and thus a deterioration of the fastness to light does no longer occur.
  • o-phenylphenol and particularly methylnaphthalenes can only be removed from the fiber by a special aftertreatment with heat, a treatment which has absolutely nothing to do with the term drying.
  • a temperature of at least 140C is necessary at which the dried goods have to be treated for at least 3 minutes in order to remove the carrier remainders to such an extent that a deterioration of the fastness to light of the dyed goods can no longer be observed.
  • dyeings and prints which are fast to light and not capable of being affected by dyeing accelerators can be prepared with insoluble dyestuffs on synthetic fiber material, preferably linear polyester fibers, by subjecting the dyeings and prints prepared in the usual manner on textile articles with aqueous dyestuff preparations with the aid of carriers to an aftertreatment in an organic solvent or solvent mixture.
  • organic solvents for the aftertreating baths there may be used according to the present process halogenated especially aliphatic hydrocarbons, alcohols, ethers, esters, etc. preferably organic solvents known from the dry-cleaning, for example perchloroethylene, trichloroethylene, l,l l-trichloroethylene, gazolines, l,2,2-trifluorotrichloroethane, methylene chloride and also lower aliphatic alcohols having one to three carbon atoms.
  • the dyed textile materials can be aftertreated subsequently at a temperature between the freezing point and the boiling point of the organic solvent used, preferably and practically at a temperature between 20C and 80C.
  • the time of treatment depends on the temperature of the aftertreating bath and is generally between 5 and 15 minutes.
  • a high temperature is selected for the aftertreating bath which is sufficiently high to be accepted according to the results of the preliminary test without too strong a staining of the aftertreating bath or an obvious brightening of the aftertreated dyeing occuring.
  • the process of the present invention is first of all suitable for dyeings on polyester fibers or mixtures of such fibers with other fibers in all stages of processing, for example flocks, slubbings, cables, filaments, yarns, fabrics, knitted fabrics, non-Wovens or finished articles.
  • This process is particularly suitable for the aftertreatment of, for example, finished articles in dry cleaning plants where a heating of the solvent bath is possible.
  • EXAMPLE A cross-wound bobbin made of polyester staple fiber yarn was treated for 90 minutes at 97C to 98C at a goods-to-liquor ratio of 1 20 in a dyebath containing calculated on the weight of the dry goods l of the disperse dyestuff of the formula and 4 g/l of a commercial carrier on the basis of methylnaphthalene, the pH of the dyebath being adjusted to 5.5 by means of acetic acid.
  • the samples aftertreated at 20C showed only a slightly weaker yellowing than the dyeing which had not been subjected to an aftertreatment.
  • the samples aftertreated at 60C and 90C showed, as already demonstrated at the treatment at 60C, no deterioration of the fastness to light.
  • the solvent dyebath was strongly stained and the dyeing distinctly bleached.
  • the tests carried out at other temperatures in perchloroethylene and those carried out in other solvents at the temperatures as indicated did in no case lead to a distinct staining of the aftertreating baths or to visible brightenings of the dyeings.
