Description

  • The present invention relates to mixtures of reactive dyes that are suitable for the dyeing or printing of nitrogen-containing or hydroxy-group-containing fibre materials and yield on such materials dyeings or prints having good reproducibility and good all-round fastness properties. The present invention relates also to a method for trichromatic dyeing or printing wherein the reactive dye mixtures according to the invention are used.
  • There is a huge demand for novel reactive dye mixtures that are suitable for the reproducible trichromatic dyeing and printing of fibre materials which fulfill highest ecological and economical requirements while still providing dyeings of the desired colour shades with good fastness properties, such as wash and water fastness and perspiration fastness. Suitable reactive dyes should provide a unique combinability and a low sensitivity to various dyeing parameters. Furthermore, they should have sufficient substantivity and at the same time have good ease of washing off of unfixed dye. They should also have a good tinctorial yield and high reactivity, the objective being to provide especially dyeings having high degrees of fixation.
  • The present invention is therefore based on the problem of providing new mixtures of reactive dyes that are suitable especially for the reproducible trichromatic dyeing and printing of fibre materials in the desired colour shades and fulfill the above indicated requirements to the highest possible extent.
  • The present invention accordingly relates to a dye mixture, comprising at least one yellow dye of the formula

  • The said textile fibre material may be in an extremely wide variety of processing forms, such as, for example, in the form of fibres, yarn, woven fabric or knitted fabric.
  • The present invention relates also to a method for the trichromatic dyeing or printing of hydroxy-group-containing or nitrogen-containing fibre materials, especially cellulosic fibre materials, which method comprises using at least one yellow dye, for example one, two or three dyes, preferably one dye, of the above-mentioned formula (1) and at least one yellow dye, for example one, two or three dyes, preferably one dye, of the above-mentioned formula (2), together with at least one red dye of the above-mentioned formula (3) and at least one blue dye of the above-mentioned formula (4).

Preferably, the method according to the invention for trichromatic dyeing and printing is carried out according to the exhaust-dyeing method, in which the goods are impregnated with aqueous, optionally salt-containing dye solutions, and the dyes are fixed after an alkali treatment or in the presence of alkali, optionally under the action of heat.

  • The amounts in which the individual dyes are used in the dyebaths or print pastes can vary within wide limits in dependence upon the desired depth of shade; in general, amounts of from 0.01 to 15% by weight, especially from 0.1 to 10% by weight, based on the goods being dyed or on the print paste, have proved advantageous.
  • The dyes of formulae (1), (2), (3), (4) and (8) used in the method according to the invention are distinguished in trichromatic dyeing or printing by uniform colour build-up, good exhaustion and fixing behaviour, good constancy of shade even in different concentrations, a low sensitivity to various dyeing parameters and, in particular, very good combinability. Dyeing times can be reduced. Furthermore, they have sufficient substantivity and at the same time have good ease of washing off of unfixed dye and can advantageously be applied at short liquor ratios, for example, at a liquor ratio of from 1:4 to 1:6, preferably, 1:6. The dyeings and prints produced in accordance with the method of the invention exhibit very good fastness properties, such as wash and water fastness and perspiration fastness, and good reproducibility.
  • The following Examples serve to illustrate the invention. Unless otherwise indicated, temperatures are given in degrees Celsius, parts are parts by weight and percentages relate to percent by weight. Parts by weight relate to parts by volume in a ratio of kilograms to litres.
    • EXAMPLE 1
  • A bleached cotton tricot fabric is introduced at 60° C. into an aqueous dyebath with a liquor ratio of 1:10 which contains 72 g/l of sodium chloride, 0.541% by weight of the yellow dyeing reactive dye of formula (201), 0.361% by weight of the yellow dyeing reactive dye of formula (101), 0.276% by weight of the red dyeing reactive dye of formula (301), 0.413% by weight of the red dyeing reactive dye of formula (302), 0.618% by weight of the blue dyeing reactive dye of formula (801) and 0.412% by weight of the blue dyeing reactive dye of formula (401). A total of 15.2 g/l of calcined sodium carbonate is added in 4 portions (1.52 g/l, 3.04 g/l, 3.04 g/l and 7.6 g/l, respectively) to the dyebath after 45, 50, 55 and 60 minutes at 60° C. Dyeing is continued for 35 minutes. The dyed fabric is taken out of the dyeing liquor and dried. A brown shaded fabric is obtained.
  • The evolution of the shade during the dyeing steps (exhaustion and fixation) is monitored by measuring the h coordinates (CIELab sysystem) from the remission curves of the respective samples (spectrophotometer Datacolor SF 600). Independent from reaction parameters like dyeing time, temperature, amount of salt or alkali, the measured shade values vary within narrow limits, i.e. the dye mixture according to the invention allows a very good shade control.
    • COMPARATIVE EXAMPLE 2
  • A bleached cotton tricot (1-4002/22) fabric is introduced at 60° C. into an aqueous dyebath with a liquor ratio of 1:10 which contains 78 g/l of sodium chloride, 0.90% by weight of the yellow dyeing reactive dye of formula (201), 0.68% by weight of the red dyeing reactive dye of formula (301) and 1.29% by weight of the blue dyeing reactive dye of formula (801). A total of 15.8 g/l of calcined sodium carbonate is added in 4 portions (1.58 g/l, 3.16 g/l, 3.16 g/l and 7.9 g/l, respectively) to the dyebath after 45, 50, 55 and 60 minutes at 60° C. Dyeing is continued for 35 minutes. The dyed fabric is taken out of the dyeing liquor and dried. A brown shaded fabric is obtained.
  • The evolution of the shade during the dyeing steps (exhaustion and fixation) is monitored by measuring the h coordinates (CIELab sysystem) from the remission curves of the respective samples (spectrophotometer Datacolor SF 600). Depending on reaction parameters like dyeing time, temperature, amount of salt or alkali, the measured shade values vary within a considerable range.
