Definitions

  • Optical brighteners are often used as mixtures of two or more different types because such mixtures have a synergistic effect in that the degree of whiteness of the mixture is higher than the degree of whiteness of the same amount of the individual components.
  • the invention therefore relates to mixtures of optical brighteners composed of 5 to 45 parts by weight of the compound of the formula I. and 95 to 55 parts by weight of one of the compounds of formulas 2 and 3
  • the mixtures of optical brighteners according to the invention preferably consist of the compounds of the formulas 1 and 2.
  • the mixtures according to the invention are obtained by mixing the compound of the formula 1 with one of the two compounds of the formulas 2 and 3 in the stated mixing ratio.
  • the preferred mixing ratio of components 1 and 2 or 1 and 3 is 10 to 40 to 90 to 60 parts by weight, in particular 10 to 30 to 90 to 70 parts by weight, and for components 1 and 2 preferably 15 to 25 to 85 to 75 parts by weight.
  • the present invention furthermore relates to the use of mixtures of the compound of the formula 1 and one of the two compounds of the formulas 2 and 3 for the optical brightening of textile material containing polyester fibers and polyester fibers, and agents for the optical brightening of textile materials containing mixtures of polyester fibers and polyester fibers the compound of formula 1 and one of the two compounds of formulas 2 and 3.
  • the mixtures according to the invention are particularly suitable for optically brightening textile materials made of linear or modified polyesters. They can be applied to the textile material by known methods, for example by the exhaust process at 90 to 140 ° C or by the pad thermal process at 160 to 220 ° C.
  • the mixtures according to the invention are distinguished by very good dyeing behavior.
  • the mixtures catalyze an improved brilliance of the brightening and good light fastness.
  • Example 1 A polyester fabric (Terylene type 540) is at 40 ° C on a dyeing machine with a liquor ratio of 1 to 20 with an aqueous bath containing 0.1% of the optical brightener in finely dispersed form, consisting of a mixture of 20 parts by weight of the compound of the formula and 80 parts by weight of the compound of the formula and treated 1 g / l of a fatty alcohol polyglycol ether.
  • the temperature is increased to 120 ° C. within 30 minutes and left at this level for a further 30 minutes. Then you cool down to 40 ° C within 15 minutes.
  • the fabric is rinsed in flowing deionized water for 30 seconds and dried at 180 ° C.
  • the polyester fabric treated in this way has a high lightening effect.
  • Example 2 Using the same procedure as in Example 1, instead of the brightener from the mixture of the compounds of the formulas 1 and 2, one from the mixture of 20 parts by weight of the compound of the formula 1 and 80 parts by weight of the compound of the formula you get similarly good lightening effects.
  • EXAMPLE 3 A polyester fabric (terylene type 540) is padded at room temperature with an aqueous liquor containing 0.1 g / l of the brightener mixture of 20 parts by weight of the compound of the formula 1 and 80 parts by weight of the compound of the formula 2 (calculated on active substance) in dispersed form and 1 ml / l Invadin JFC 200%. The squeezing effect is 65%.
  • the polyester fabric treated in this way has a high lightening effect.
  • EXAMPLE 4 If a brightener mixture of 20 parts by weight of the formula 1 and 80 parts by weight of the formula 3 is used instead of the brightener mixture of the compounds of the formulas 1 and 2 using the same procedure as in Example 3, similarly good lightening effects are obtained.
