Abstract

The invention provides a dispersed deep blue dye composition, which mainly comprises a component A shown as a formula (I) with one or more structures, a component B shown as a formula (II) with one or more structures, and a component C shown as a formula (III) with one or more structures; and based on the component A, the component B and the component C, the component A is 20 to 99 mass percent, the component B is 0.1 to 40 mass percent and the component C is 0.1 to 50 mass percent. When the dispersed deep blue dye composition is used for dyeing hydrophobic fiber materials, the dyeing residue is clear and the flooding is a little; by adjusting a ratio of the components, deep blue dyed fabrics with good lifting property, washing fastness, friction fastness and sublimation fastness can be obtained; and the dispersed deep blue dye composition is suitable for dyeing high-grade fabrics such as super-fine fabrics, polyester / cotton blend fabric, polyester / ammonia blend fabric and the like.

Description

(1) Technical field The invention relates to a disperse dark blue dye composition suitable for printing and dyeing textile fiber materials, especially hydrophobic fiber materials. (2) Background technology In recent years, since spandex-containing fabrics have excellent resilience properties, are soft to the touch, and are comfortable to wear, they have been used more and more, for example, they are combined with polyester to make polyester / spandex elastic fabrics. 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 penetrate polyester well, and...
