Definitions

  • the present invention relates to a method for improving the light fastness of polyamide fibers dyed with acid dyes or metal complex dyes by treatment with copper complex compounds before, during or after the dyeing.
  • plastic materials such as. B. polyamide fibers, which may contain any dyes, can be stabilized with metal complexes from Schiff bases.
  • metal complexes from Schiff bases.
  • chelates of salicylaldehyde derivatives and Sc, Ti, V, Cr, Mn, Co, Cn and especially Ni are used, inter alia, for improving the light fastness of cellulose materials dyed with vat dyes.
  • the compounds (II) and (III) are used in amounts of 0.5 ⁇ 4, preferably 1 ⁇ 2%, based on the weight of the polyamide.
  • the compounds (1) are obtained in a manner known per se (cf., for example, US Pat. No. 3,361,710) by reacting the corresponding starting compounds with - preferably stoichiometric amounts - a copper salt, in particular a salt of a mineral acid such as copper-II -chloride in preferably alcoholic or aqueous-alcoholic medium.
  • Polyamide is understood to mean natural and synthetic polyamide.
  • the dyeings can be produced in a conventional manner using both metal complex dyes and acid dyes.
  • the known types in particular the 1: 2 chromium or 1: 2 cobalt complexes of mono- or disazo dyes, which are described in large numbers in the literature, are used as metal complex dyes.
  • the dyes can in particular also contain 1-2 sulfo groups.
  • Suitable acid dyes are commercially available types, which are preferably used in combination with the metal complex dyes.
  • the compounds I are of course used in finely divided form, as is obtained by grinding in the presence of customary dispersants.
  • 100 g of polyamide 6 fibers are introduced into 2000 ml of an aqueous dye liquor, which contains 0.1 g of the copper complex of the formula and 0.5 g of the metal complex dye of the formula contains.
  • a pH of 6 is set by adding acetic acid. Then the temperature of the liquor is slowly increased with occasional stirring. It is dyed at 98 ° C for 1 hour.
  • the goods are then removed from the dye bath and rinsed thoroughly.
  • the dyeing produced in this way shows improved lightfastness compared to the dyeing not treated with (1).
  • the staining can also be done under HT conditions, i.e. H. at temperatures of 110-130 ° C in an autoclave.
  • a polyamide 6 fabric 100 g of a polyamide 6 fabric are placed in 2000 ml of an aqueous dye liquor containing 0.5 g of the metal complex dye of the formula (2). It is dyed in the usual way at 98 ° C. and pH 6. After rinsing, drying is carried out and the polyamide fabric is impregnated with a liquor on a padder; which contains 1 g of compound (1) in dispersed form per liter of water.
  • the pressure of the foulard rollers is set so that the impregnated polyamide doubles its dry weight when wet.
  • the dyeing treated in this way shows improved lightfastness compared to the dyeing not treated.
  • a further improvement in light fastness can be achieved if an impregnating liquor is used which contains 10.0 g of compound (3) in addition to (1).
  • the dyeing produced in this way shows improved lightfastness compared to the dyeing not treated with (1).
  • a further improvement in light fastness is achieved if, in addition to (1), 1.0 g of compound (3) are added to the liquor.
