Problems solved by technology

However, due to the different specific surface areas of the structural fibers, polyester fibers of different deniers exhibit certain application deficiencies, such as, for example, relatively poor leveling or migration properties, excessive dependence of color yield on different dyeing parameters in the dyeing process or Insufficient dye build-up on polyester, or unsatisfactory fastness properties
[0003] In many respects, efforts to extend or complement the range of dyes with modern disperse dyes have reached limits which, if at all, can only be overcome insufficiently with individual dye components

Embodiment 1

[0053] A blue dye mixture comprising 16.4 parts of the dye of formula (1), 5.7 parts of the dye of formula (3) and 10.6 parts of the dye of formula (2-1) was prepared by mixing the three dyes together and then mixing them in 40 % in the form of an aqueous slurry is ground with 20 parts of a high temperature stable dispersant until the dye particle size (average diameter) is 0.1-5 microns.

[0054]

[0055]

[0056] The dispersion was standardized to 32.7% mixture and 67.3% dispersant in solid form by adding 47.3 parts of heat stable dispersant and drying in a spray dryer to granule or powder form.

[0057] A yellow dye mixture comprising 5.9 parts of the dye of formula (4), 4.4 parts of the dye of formula (5) and 2.6 parts of the dye of formula (6-1) was prepared by mixing the three dyes together and then mixing them at 40% The form of an aqueous slurry is ground with 20 parts of a high temperature stable dispersant until the dye particle size (average diameter) is 0.1-5...

Embodiment 2

[0067] The preparation, dyeing and evaluation of the dye mixture were carried out in the same manner as in Example 1 except that the recipe was changed to the following:

[0068] The blue dye mixture comprises 18.2 parts of formula (1) dyes, 5.1 parts of formula (3) dyes and 8.0 parts of formula (2-1) dyes;

[0069] The yellow dye mixture comprises 5.9 parts of the dye of formula (4), 5.0 parts of the dye of formula (5) and 2.0 parts of the dye of formula (6-1); and

[0070] The red dye mixture comprises 9.1 parts of the dye of formula (7), 8.45 parts of the dye of formula (8) and 9.0 parts of the dye of formula (9). The results are given in Table 1.

Embodiment 3

[0072] The preparation, dyeing and evaluation of the dye mixture were carried out in the same manner as in Example 1 except that the recipe was changed to the following:

[0073] The blue dye mixture comprises 13.0 parts of the dye of formula (1), 6.5 parts of the dye of formula (2-1), 8.4 parts of the dye of formula (3) and 6.5 parts of the dye of formula (2-2):

[0074]

[0075] The yellow dye mixture comprises 4.6 parts of the dye of formula (4), 5.7 parts of the dye of formula (5) and 2.6 parts of the dye of formula (6-1); and

[0076] The red dye mixture comprises 7.0 parts of the dye of formula (7), 14.0 parts of the dye of formula (8) and 7.0 parts of the dye of formula (9). The results are given in Table 1.

Abstract

Disperse non-azo dyestuff mixture comprising: a blue dye mixture comprising a compound of the following formula (1) <CHEM> at least one compound of the following formula (2) <CHEM> wherein R<1> is C1-C4 alkyl such as methyl, ethyl n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl or tert-butyl, 3-methoxypropyl, 3-ethoxypropyl and 3-methoxyethoxypropyl and a compound of the following formula (3) <CHEM> a yellow dyestuff mixture comprising a compound of the formula (4) <CHEM> a compound of the following formula (5) <CHEM> and compound of the following formula (6) <CHEM> wherein R<2> is methyl and ethyl; and a red dye mixture comprising a compound of the following formula (7) <CHEM> a compound of the following formula (8) <CHEM> and a compound of the following formula (9) <CHEM> a method for the preparation of such mixtures and a method for colouring a synthetic textile material or fibre blend thereof using such mixtures.

Description

technical field [0001] The present invention relates to non-azo disperse dye mixtures. Background technique [0002] Polyester fiber products of different deniers, including polyester fibers with fine deniers such as 0.1 denier to 0.7 denier and polyester fibers with ordinary deniers such as 1 denier to 5 denier, are usually dyed by conventional dyeing methods Carried out with known disperse dyes. However, due to the different specific surface areas of the structural fibers, polyester fibers of different deniers exhibit certain application deficiencies, such as, for example, relatively poor leveling or migration properties, excessive dependence of color yield on different dyeing parameters in the dyeing process or Insufficient dye build-up on polyester, or unsatisfactory fastness properties. [0003] In many respects, efforts to extend or supplement the range of dyes with modern disperse dyes have reached limits which, if at all, can only be overcome insufficiently with in...
