Example Embodiment

[0021] Example 1

[0022] On the basis of the total mass of the acetate fiber monoazo dye mixture, first use 10% compound A as shown in formula (I), 10% compound B as shown in formula (II), and 40% as formula (III) As shown in the compound C, the balance of the dispersant is weighed out. The dispersant is made by mixing sodium methyl naphthalene sulfonate formaldehyde condensate and sodium lignosulfonate in a mass ratio of 3:7, and then The above components are mixed uniformly and then water is added for grinding. The slurry obtained by grinding is spray-dried. The process conditions of spray-drying are: the inlet temperature is 120°C, the outlet temperature is 50°C, and after drying, an acetate with a particle size of 0.1um is obtained Fiber monoazo dye mixture.

Example Embodiment

[0024] Example 2

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

Example Embodiment

[0026] Example 3

[0027] The difference between this example and Example 1 is that: weigh the components according to the ratio of 40% of compound A, 5% of compound B, 50% of compound C, and the rest of the dispersant; Formaldehyde condensate of sodium naphthalene sulfonate and sodium lignosulfonate are mixed at a mass ratio of 2:3; the process conditions of spray drying are: inlet temperature 130°C, outlet temperature 60°C, and the particle size is 1um after drying Acetate fiber monoazo dye mixture, the rest are exactly the same.

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...
