Embodiment 1

[0022] Based on the total mass of the monoazo dye mixture of acetate fiber, 10% of the compound A shown in the formula (I), 10% of the compound B shown in the formula (II), and 40% of the compound B shown in the formula (III) Shown compound C, the proportioning ratio of the remaining dispersant takes each component, wherein the dispersant is formed by mixing sodium methylnaphthalene sulfonate formaldehyde condensate and sodium lignin sulfonate in a mass ratio of 3:7, and then Mix the above-mentioned components evenly, add water to grind, and spray-dry the slurry obtained by grinding. The spray-drying process conditions are: inlet temperature 120°C, outlet temperature 50°C, after drying, acetate with a particle size of 0.1um is obtained. Mixture of fiber monoazo dyes.

[0023]

Embodiment 2

[0025] The difference between this embodiment and Example 1 is that each component is weighed according to the proportion of 20% compound A, 20% compound B, 30% compound C, and the remaining dispersant; Sodium naphthalene sulfonate formaldehyde condensate and sodium lignosulfonate are mixed at a mass ratio of 10:21; the spray drying process conditions are: inlet temperature 125°C, outlet temperature 55°C, and the particle size after drying is 0.5um The acetate fiber monoazo dye mixture, the rest is exactly the same.

Embodiment 3

[0027] The difference between this embodiment and Example 1 is that each component is weighed according to the proportion of 40% compound A, 5% compound B, 50% compound C, and the remaining dispersant; Sodium naphthalene sulfonate formaldehyde condensate and sodium lignosulfonate are mixed at a mass ratio of 2:3; the spray drying process conditions are: inlet temperature 130°C, outlet temperature 60°C, after drying, the particle size is 1um Acetate monoazo dye mixture, the rest is identical.

Abstract

The invention discloses an acetate fiber monoazo dye mixture. According to the total mass of the dye mixture, the acetate fiber monoazo dye mixture comprises the following active ingredients in percentage by weight: 10-40% of compound A, 5-30% of compound B, 0.5-50% of compound C, and the balance of dispersing agent, or 10-40% of compound A, 3-30% of compound D, 1-40% of compound E, and the balance of dispersing agent, or 2-35% of compound A, 5-25% of compound B, 0.1-10% of compound C, 4-20% of compound D, 5-30% of compound E, and the balance of dispersing agent. The acetate fiber monoazo dye mixture is reasonable in formula, excellent in dying performance, wide in applications, high in the added value of the product, and can be used for dying acetate fibers under the low-temperature condition. The invention further discloses a preparation method of the acetate fiber monoazo dye mixture, which comprises the following steps of: mixing all the active ingredients according to a proportion, adding water and grinding, and conducting spray drying, and the preparation method is simple in technology steps, strong in operability, low in cost, and suitable for industrial production.

Description

technical field [0001] The invention relates to a dye, in particular to an acetate fiber monoazo dye mixture and a preparation method and application thereof. Background technique [0002] In Italy, where the garment industry is developed, acetate filament has been used in 31.1% of garment fabrics, and 27% in decorative textiles, almost forming a third of the world with traditional garment linings. Since the 1990s, with the high-grade clothing level of Chinese people, acetate filaments and fabrics have poured into our country. It is widely used in high-end clothing fabrics, linings, dresses, silk scarves, ties, pajamas, etc. Acetate filament and its composite silk fabrics are very popular in the clothing industry. However, there are relatively few factories producing acetate dyes at home and abroad, and imported dyes are relatively expensive. Therefore, the development of dyes for acetate fibers is conducive to improving the competitiveness of the international market. Co...
