Description

(I) Technical Field

[0001] This invention relates to a blue to black disperse dye composition and dye articles. (II) Background Technology

[0002] In recent years, polyester-spandex blended fabrics have become popular in the market due to their good elasticity, wrinkle resistance, skin-friendliness, and sweat absorption. Furthermore, these blended fabrics are easy to clean, requiring only hand washing, machine washing, and dry cleaning, and generally do not cause any damage to the fabric, meeting the needs of sportswear and other mid-to-high-end apparel fabrics. Currently, the disadvantage of this blended fabric is that its stability is relatively worse than pure polyester fabrics, and it is prone to color fading. Therefore, higher requirements are placed on its coloring dyes. Among disperse dyes, blue-black series dyes are the most widely used, but the color fastness of blue-black dyes currently used in polyester-spandex blended fabrics on the market needs further improvement. (III) Summary of the Invention
