Technical Field

The present invention relates to a disperse yellow dye composition and dye preparations and their use for dyeing and printing hydrophobic synthetic materials or for the dope-dyeing of hydrophobic synthetic materials.

Background

The low-temperature three primary colors commonly used in the printing and dyeing industry at present are disperse yellow E-G L200% (C.I.Y54 complex type), disperse red FB 200% (C.I.R60) and disperse blue 2B L N100% (C.I.B56), wherein the light fastness of the disperse yellow E-G L200% is poor and is more than one grade different from that of the disperse red FB 200% and the disperse blue 2B L N100%.

The current printing and dyeing process pursues a short flow, for example, the polyester dyeing pretreatment is popular compared with dyeing one bath, but the alkali resistance requirement on disperse dye is higher, and the pH dependence is generally required to be more than 9. The alkali resistance of disperse yellow 54 is pH 3-9, the color fading is more when the pH is more than 9, and the disperse yellow is obviously not suitable for the process of short flow of a dye house. Therefore, the economic low-temperature disperse yellow with excellent performance and light environmental protection pressure can be popularized as a new low-temperature three-primary color.

Patent CN104356688A discloses a yellow disperse dye composition, which is prepared by coupling o-nitroaniline and m-nitroaniline as diazo components with N-ethyl-cyanoethylaniline to obtain a yellow dye compound, and then adding a third orange component to obtain a yellow light similar to that of disperse yellow E-G L instead of the yellow color.

2-aminobenzonitrile is used as a pesticide intermediate, the application of the pesticide intermediate to dyes, particularly diazo components of disperse dyes is rarely reported, and no disperse dye containing the structure is considered, researched and utilized for a long time. The disperse dyes using o-chloroaniline as diazoaniline have not been well used, probably because the dyes of this intermediate tend to have a relatively low melting point and are not well developed for practical use. In fact, selection of suitable coupling components can increase the melting point to give dyes with good properties.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a disperse yellow dye composition and a dye product, which have the characteristics of excellent fastness, good lifting power, good alkali resistance and the like when being applied to dyeing or printing of hydrophobic fiber materials.

The technical scheme of the invention is as follows:

a disperse yellow dye composition comprises a component A and a component B, wherein the component A is selected from at least one of dye monomer compounds with structures shown in formulas (I-1) to (I-10), the component B is selected from at least one of dye monomer compounds with structures shown in formulas (II-1) to (II-16), based on the component A and the component B, the mass fraction of the component A is 60-99%, and the mass fraction of the component B is 1-40%;

further, the disperse yellow dye composition comprises a component A and a component B, wherein the mass fraction of the component A is 60-99%, and the mass fraction of the component B is 1-40%.

When the disperse yellow dye composition is sold as a commodity or applied to coloring textile materials, an auxiliary agent is usually added for post-treatment.

Therefore, the invention also provides a disperse yellow dye product, which contains the disperse yellow dye composition and an auxiliary agent, wherein the weight ratio of the auxiliary agent to the disperse yellow dye composition is 0.2-6: 1. the auxiliary agent is selected from one of the following or a mixture of more than two of the following: naphthalene sulfonic acid formaldehyde condensate, lignosulfonate, alkyl naphthalene sulfonic acid formaldehyde condensate, benzyl naphthalene sulfonic acid formaldehyde condensate, and sodium lignosulfonate.

The preparation method of the disperse yellow dye product comprises the following steps: mixing the dye monomer compounds (crude dyes) which form the disperse yellow dye composition according to a ratio, and then carrying out microparticulation by a grinder such as a sand mill or a grinding machine in the presence of an auxiliary agent and water; alternatively, the dye monomer compound may be subjected to a pulverization treatment using a pulverizer such as a sand mill or a grinder in the presence of an auxiliary agent or water, and then mixed in a certain proportion.

The disperse yellow dye product of the invention is liquid after being ground by a sand mill or a grinding mill, and can be powder and granular after being spray-dried, which is a preparation method known by the technical personnel in the field, and because 100 percent of water cannot be removed in the spray-drying process, a certain amount of water is still allowed to exist in the powder or granular dye product. Due to the particularity of the dye industry, the dye product is difficult to prepare into a pure product, usually has impurities in the preparation process, and the dye product of the invention also allows the existence of trace impurities.

The disperse yellow dye composition provided by the invention is further allowed to be compounded with other dyes to be synergistic to prepare a new composition, or other red, yellow or orange toning components and the like are added.

The disperse yellow dye composition and the dye product can be applied to dyeing and printing of hydrophobic synthetic materials or the dope dyeing of the hydrophobic synthetic materials.

The dye prepared by the dye composition can dye hydrophobic fiber materials (such as polyester and blended fabrics thereof) in a conventional mode in the industry, such as dyeing by a common dip dyeing method or a high-temperature high-pressure dyeing method, and can also be used for direct printing. Wherein, the common dip-dyeing method comprises the steps of pretreating the hydrophobic fiber material, putting the hydrophobic fiber material into a dye vat for dip-dyeing, washing the hydrophobic fiber material to be neutral by cold water after dyeing, wringing, reducing, washing and drying; the direct printing is to carry out dyeing pretreatment, drying and setting on the fabric, print disperse dye color paste on a printing machine, then carry out steaming, fix the color of the dye on the fabric by using a steaming mode, finally wash and tenter setting.
