Definitions

  • the present invention relates to a new, improved process for the optical brightening of polyester fibers in the exhaust process with the aid of conventional polyester brighteners with the use of shading dyes.
  • the process according to the invention for the optical brightening of polyester fibers in the exhaust process by treating the fibers in an aqueous polyester brightener which contains one or more polyester bristles which are stable under the application conditions and which absorbs onto the substrate, and a small amount of a blue to violet disperse dye or mixtures of such dyes as shading dye Dispersion is characterized in that the treatment in said dispersion is carried out at a pH of more than 9.
  • the dispersion has a pH between 11 and 14, e.g. between 11 and 13.5, in particular between 11 and 12.5.
  • the pH is adjusted using a suitable alkaline substance, preferably using alkali metal hydroxides, in particular using KOH, but especially NaOH.
  • the treatment is carried out in the usual manner at a temperature between room temperature and 140 ° C., in particular between 50 ° and 130 ° C. It is advantageous to deal with the fiber material at a lower temperature (e.g. 50 ° C), whereupon the temperature is increased (e.g. to 120 ° C).
  • practice is preferably carried out under high temperature (HTI conditions, that is to say the fibers are treated in a conventional HT dyeing machine above 100 ° C., for example between 100 and 130 ° C, e.g. at 120 ° C.
  • HMI conditions that is to say the fibers are treated in a conventional HT dyeing machine above 100 ° C., for example between 100 and 130 ° C, e.g. at 120 ° C.
  • carrier additives can also be used under HT conditions.
  • Suitable carriers are those customary in dyeing practice, for example aromatic hydrocarbons, aromatic halogenated hydrocarbons and esters and ethers of aromatic carboxylic acids.
  • Preferred carriers are dichlorobenzenes and trichlorobenzenes, optionally also diphenyl and mixtures of the substances mentioned.
  • the duration of the treatment of the textiles in the brightener dispersion can vary within wide limits, but an application duration of at least 20 to 30 ° minutes is advantageous.
  • the amount of brightener (pure substance) in the dispersion can, depending on the brightener used, vary between 0.002 and 0.5%, based on the material to be lightened.
  • the amount of shading dye is, depending on the dye and the desired shade, about 0.0025-2.5%, preferably 0.025-1.25%, based on the amount of brightener (pure substance) used.
  • polyester brighteners are used as brighteners, which in practice are applied together with shading dyes. These are mostly benzoxazole, stilbene and naphthalimide brighteners.
  • rings A, B and C may also contain simple radicals, such as lower alkyl or alkoxy groups or chlorine atoms, especially 2,5-bis-benzoxazol-2-yl-thiophene, 2,5-bis- (5- Methylbenzoxazol-2-yl) ethylene and 1,4-bis-benzoxazol-2-yl-naphthalene; or the formula in which n denotes 0 or 1 and the rings A and B can be further substituted, for example with alkyl, alkoxy, phenyl, chlorine, cyano, carboxy and their derivatives, for example the compounds: 4-phenyl-4 '- (5-t-butylbenzoxazole -2-yl) stilbene, 4-phenyl-4 '- (5,8-dimethylbenzoxa
  • stilbene brighteners are those of the formulas respectively. in which the rings A, B and C can carry different substituents, such as alkyl, alkoxy, chlorine, cyano, carboxy and its derivatives etc., to mention, in particular the compounds 2-cyano-4- (naphtho [1,2-d ] v-triazol-2-yl -) - 4'chlorstilbene, 4- (naphtho [1,2-d] v-triazol-2-yl) -4'-methoxycarbonylstilbene, and 1,4-bis- (2- Cyanostyryl) benzene.
  • substituents such as alkyl, alkoxy, chlorine, cyano, carboxy and its derivatives etc.
  • naphthalimide brighteners are those of the formula wherein R and R 2 is hydrogen or alkoxy, to mention, in particular as n particular those wherein R 1 is hydrogen and R 2 is methoxy or wherein R and R 2 are each ethoxy.
  • Blue to violet disperse dyes are used as shading dyes, which of course must be suitable for treatment in an alkaline liquor.
  • Acylaminoanthraquinone dyes are preferably used, in particular those of the formula in which the benzene rings A can be optionally substituted, for example by alkyl, alkoxy, halogen etc.
  • Dyes whose benzene rings A are unsubstituted or substituted in the para position with chlorine or methoxy are particularly suitable.
  • the aqueous dispersion advantageously also contains one or more dispersants and, if appropriate, wetting agents, stabilizers and / or other customary dyeing auxiliaries.
  • Suitable dispersants include: alkali metal salts, especially sodium salts of alkyl or alkylarylsulfonic acids and carboxylic acids, alkali metal salts, especially sodium salts of condensation products from arylsulfonic acids with formaldehyde, macromolecular substances which are suitable for liquefying and dispersing, carboxy latex of the polymerized maleic acid or polymerized acrylic acid type and copolymers of maleic acid with allyl acetate.
  • particularly preferred dispersants are nonionogenic, water-soluble ethoxylated or propoxylated fatty alcohols and alkylphenols and fatty alcohol polyglycol ethers, for example alkanals, alkenols (C 8 -C 22 ) with different amounts of ethyleneoxy or propyleneoxy groups, alkyl or arylpolyglycol ethers with up to 50 ethyleneoxy or propylene y phenomenon ox, such as octyl, nonyl or Dodecylphenolpolyglykolreliher.
  • the individual components can be introduced separately into the treatment bath, which is already alkaline or is only then adjusted to the desired pH.
  • Such dispersions contain brightener and dye in the desired ratio. They are prepared by introducing the brightener and dye, preferably together with a dispersant, into a small amount of water. It is advantageous if this dispersion is subjected to grinding (for example in a ball mill) in order to achieve particle sizes of less than 10 ⁇ m, preferably less than 2 ⁇ m to obtain.
  • this stock dispersion can then be introduced (calculated on the desired amount of brightener in the bath) into the treatment bath, which may also contain a dispersant and / or other auxiliaries.
  • the treatment bath which may also contain a dispersant and / or other auxiliaries.
  • the bleaching bath can then be bleached directly.
  • Sodium chlorite is preferably added to the liquor, the alkaline bath is acidified and then heated to about boiling temperature.
  • polyester fibers naturally also include polyester fibers in blended fabrics, e.g. to be understood in mixed fabrics polyester / cotton.
  • the nuanced lightening of such blended fabrics by the process according to the invention can also be advantageous with the lightening of the cotton portion, with the bleaching (e.g. with peroxide) and / or the various customary finishing and finishing processes (e.g. crease-resistant, wash and wear, soft handle and other equipment) can be combined.
