Problems solved by technology

[0003] For home textile products (such as curtains), automotive upholstery and other textiles exposed to sunlight for a long time, it is necessary to select dyes that are resistant to sunlight to meet the conditions. Currently, most of the disperse blue 366 and disperse blue 79 on the market are mainly It is an azo structure, which is more easily affected by ultraviolet light, so its light fastness is generally not good

Abstract

The invention discloses a dispersed blue dye composition. The dispersed blue dye composition comprises following components in parts by mass: 4-8 parts of a component A, 28-35 parts of a component B, 9-11 parts of a component C, 3-5 parts of a component D and 46-59 parts of a component E. According to the dispersed blue dye composition, the sunlight fastness of all the components is excellent; a product is applied to dyeing dacron and blended fabrics thereof; the sunlight fastness of the dyed fabrics can be more than 250 hours and can completely reach the requirements of cloth for home textiles and car textiles; the industrial application value is high.

Description

technical field [0001] The invention relates to the field of preparation of disperse dye compositions, in particular to a disperse blue dye composition with high light fastness. Background technique [0002] Dyed textiles are exposed to sunlight for a long time, and sunlight contains ultraviolet light. Under the action of ultraviolet light, the chemical bonds in the dye will change or even break, destroying the structure of the chromophoric group and auxochromic group in the dye. Thereby losing color; it is also possible that under the irradiation of ultraviolet rays, the three-dimensional structure of the dye changes, resulting in a change in color, showing color change. [0003] For home textile products (such as curtains), automotive upholstery and other textiles exposed to sunlight for a long time, it is necessary to select dyes that are resistant to sunlight to meet the conditions. Currently, most of the disperse blue 366 and disperse blue 79 on the market are mainly I...
