Embodiment 1

[0030] A high washing fastness disperse ruby ​​dye composition, every 100g is mixed by the following components: Disperse Violet A30g, Disperse Ruby 50g, Disperse Violet B10g, auxiliary agent 10g, said auxiliary agent is benzenesulfonic acid formaldehyde Condensate:

[0031] The disperse violet A is a dye compound represented by formula (1-1):

[0032] R 1 for Br,

[0033] The disperse carnelian is a dye compound shown in formula (2):

[0034]

[0035] The disperse violet B is a dye compound represented by formula (3):

[0036]

[0037] Mix the disperse violet A shown in the formula (1), the disperse carnelian shown in the formula (2), and the disperse violet B shown in the formula (3) in proportion, and then pulverize the spheroidal ink in the presence of additives and water, The amount of water used is 120g, and then spray-dried to obtain a disperse ruby ​​dye composition product with high washing fastness.

[0038] The concrete steps of embodiment 2~9 are with ...

Abstract

The invention relates to dye compositions, in particular to a high washing fastness dispersed red dye composition. The high washing fastness dispersed red dye composition aims at overcoming the defects that a dye composition is poor in color fastness in the prior art. The high washing fastness dispersed red dye composition is composed of, by weight, 30 % to 40 % of dispersed purple A, 30 % to 55 % of dispersed red dye, 10 % to 30 % of dispersed purple B in a mixing mode and the balance auxiliaries, wherein the dispersed purple A is one of two kinds of dye compounds shown in a formula (1): R1 in the formula (1) is Br or Cl; the dispersed red dye is dye compounds shown in a formula (2); the dispersed purple B is dye compounds shown in a formula (3); the rest of the high washing fastness dispersed red dye composition is auxiliaries. When the high washing fastness dispersed red dye composition is used for dyeing of spandex fabrics, dyeing effect is good, color fastness is good, and the quality of the spandex fabrics can be greatly improved.

Description

technical field [0001] The invention relates to a dye composition, in particular to a disperse ruby ​​dye composition with high washing fastness. Background technique [0002] In recent years, since spandex-containing fabrics have excellent resilience properties, are soft to the touch, and are comfortable to wear, they have been more and more widely used, such as polyester / spandex elastic fabrics made of polyester composites. At present, disperse dyes are mainly used for dyeing polyester / spandex elastic fabrics. Due to the structural characteristics of spandex, disperse dyes are easy to dye spandex and desorb at the same time, so the color fastness of this type of product is reduced. In addition, due to the existence of spandex, in order to avoid damage to the performance of spandex, high-temperature dyeing of polyester is limited, while low-temperature dyeing often makes it impossible for disperse dyes to dye polyester well, and the dyeing rate and promotion rate of polyest...
