Disperse orange dye composition, disperse orange dye, preparation method and application of disperse orange dye, and colored article

Abstract

The invention provides a disperse orange dye composition, a disperse orange dye, a preparation method and application of the disperse orange dye, and a colored article. The disperse orange dye composition is prepared from the components in percentage by mass: 1%-99% of disperse orange A and 1%-99% of disperse violet B; the disperse orange dye is prepared from the disperse orange dye composition; the preparation method of the disperse orange dye comprises the steps: the disperse orange dye composition, an auxiliary and water are mixed and then granulated to obtain the disperse orange dye; as for the application of the disperse orange dye, the disperse orange dye is used for dyeing and printing of synthetic fibers and blended materials of the synthetic fibers; and the colored article is obtained by being dyed or printed through the disperse orange dye. The disperse orange dye composition and the disperse orange dye provided by the invention are excellent in compatibility, wide in dyeingpH value, excellent in sublimation washing fastness, and more environmentally friendly than disperse orange 30 or orange 61 products, the color yield of the disperse orange dye composition and the disperse orange dye is two times that of commercially-available traditional products, COD of after-dyeing residual liquid of dyeing at the same depth is low, and the disperse orange dye composition and the disperse orange dye can directly substitute the traditional products and are excellent in cost performance.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a disperse orange dye composition, a disperse orange dye, a preparation method and application thereof, and a colored product. Background technique [0002] For conventional disperse orange dyes, the market is dominated by disperse orange 30 or orange 61, both of which are monochromatic products: disperse orange 30 is an orange product with excellent fastness and good performance, which has been used for a long time. [0003] However, due to the limited environmental indicators of Disperse Orange 30, the product’s chlorobenzene and polychlorinated phenols seriously exceeded the standard, and product returns occurred many times in the market. higher. [0004] In addition, there are still a large number of disperse oranges currently on the market, all of which are compounded with disperse orange 288 or orange 25, etc. It is expected that there will be a high cost-effective disperse orange dye...
