Abstract

The invention relates to a dye composition, in particular to a high washing fastness dispersed dark blue dye composition. The high washing fastness dispersed dark blue dye composition is composed of 35 % to 50 % of dispersed red, 20 % to 40 % of dispersed golden yellow, 10 % to 30 % of dispersed purple and 10 % to 30 % of dispersed yellow in a mixing mode, and the balance auxiliaries. The dispersed red is the combination of one or more kinds of compounds shown in a formula (1); the dispersed golden yellow is the combination of one or more kinds of compounds shown in a formula (2); the dispersed purple is the combination of one or more kinds of compounds shown in a formula (3), and the dispersed yellow is the combination of one or more kinds of compounds shown in a formula (4); when the high washing fastness dispersed dark blue dye composition is used for dyeing of spandex fabrics, the dyeing effect is good, the 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 dark blue 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 poly...
