Embodiment 1

[0079] Based on the total mass of the disperse dye composition, 10% such as formula (I) component A, 8% such as formula (II) component B, 12% such as formula (III) component C, 17% such as formula (IV) -2) component D, 15% such as formula (V) component E, 5% such as formula (VI-1) component F, 3% such as formula (VI-2) component F, 10% such as formula (VII) ) Component G, the proportioning ratio of the remaining dispersant takes each component, wherein the dispersant is formed by mixing methylnaphthalenesulfonic acid formaldehyde condensate and sodium lignosulfonate in a mass ratio of 3:7, and then the above After the components are mixed evenly, water is added for grinding, and the slurry obtained by grinding is spray-dried. The spray-drying process conditions are: inlet temperature 125°C, outlet temperature: 60°C, after drying, a disperse dye composition with a particle size of 1 μm is obtained. .

Embodiment 2

[0081] The difference between this embodiment and Example 1 is: by 13% such as formula (I) component A, 5% such as formula (II) component B, 15% such as formula (III) component C, 5% such as Formula (IV-1) component D, 6% such as formula (IV-3) component D, 18% such as formula (V) component E, 3% such as formula (VI-3) component F, 5% such as Formula (VI-4) component F, 13% such as formula (VII) component G, the proportioning ratio of the dispersant of surplus takes each component, all the other dispersants are made of sodium methylnaphthalene sulfonate formaldehyde condensate and wood Sodium sulfonate is mixed at a mass ratio of 2:3, and the rest are identical, so details will not be repeated here.

Embodiment 3

[0083] The difference between this embodiment and Example 1 is: by 18% such as formula (I) component A, 8% such as formula (II) component B, 8% such as formula (III) component C, 3% such as Formula (IV-4) component D, 4% such as formula (IV-5) component D, 25% such as formula (V) component E, 5% such as formula (VI-5) component F, 8% such as Formula (VI-6) component F, 5% such as formula (VII) component G, the proportioning ratio of the dispersant of surplus takes each component, and all the other dispersants are made of sodium methylnaphthalene sulfonate formaldehyde condensate and wood Sodium sulfonate is mixed at a mass ratio of 2:3, and the rest are identical, so details will not be repeated here.

Abstract

The invention relates to the field of dyes, in particular to a disperse black dye composition, a disperse black dye preparation and application thereof. The dye composition comprises disperse red (I),disperse orange (II), disperse blue (III), disperse yellow (IV), disperse blue (V), disperse blue (VI) and basic blue (VII). When the disperse dye is used for dyeing an acetate fiber material, the acetate fiber material with bright color, high dyeing degree after dyeing, good leveling property, extremely high fastness, especially washing fastness and very good dyeing stability can be obtained through the proportions of different components. The high-washing disperse black dye composition is used for dyeing and printing acetate fibers.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a disperse black dye composition, a disperse black dye preparation and applications thereof. Background technique [0002] Most of the currently used dyes have poor color fastness, especially the washing fastness is less than grade 4, and dyes that can be used on acetate fibers and have excellent washing fastness are even rarer. Acetate dyes are very sensitive to temperature. When the dyeing temperature is uneven or too high, it will cause poor appearance or color flowers, and dyeing at low temperature is often caused by disperse dyes. During the dyeing process, some dyes always fail to enter Inside the fabric, it can only be adsorbed on the surface to form floating colors, which seriously affect the washing fastness of the fabric. [0003] The reasons for the low washing fastness mainly include two aspects. On the one hand, during the dyeing process, there are always some dyes that fail to ...
