Description

Technical Field

[0001] The present application relates to the field of dyes, and particularly to a dye composition, a dye product, and a dyed product. Background Art

[0002] In recent years, disperse dyes with high wash fastness for polyester microfiber and synthetic fiber have become a research and development hotspot in the dye industry. However, the currently available high-fastness disperse dyes on the market generally have the characteristics of poor color yield, poor sublimation fastness, serious dyeing staining (floating color) (requiring reduction washing), or intolerance to high-temperature (above 170 °C) setting, and are relatively expensive, unable to fully meet the needs of customers and the market. For example, some existing high-fastness dyes have acceptable color yield but poor water fastness after soaking, require reduction washing after dyeing, and are intolerant to high-temperature setting; again, some existing high-fastness dyes have a wide dyeing pH range, are high-temperature resistant, do not require reduction washing after dyeing, and have good water fastness after soaking, but their color yield is about 20 - 30% lower and the leveling property is poor.

[0050] The following will describe the implementation scheme of the present application in detail with reference to specific examples, but those skilled in the art will understand that the following examples are only used to illustrate the present application and should not be considered to limit the scope of the present application. If no specific conditions are specified in the examples, the experiment was carried out under conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

[0051] The dye monomer compounds used in the examples are all existing dyes, and the preparation methods can refer to CN113563737A, CN118703057 A, etc.

[0052] Example 1

[0053] According to the mass of compound A-1 (7.9 g), the mass of formula B-1 (11.5 g) was compounded to obtain a disperse dye composition, and then 70.6 g of dispersant MF, 10 g of lignin and an appropriate amount of water were added, and the mixture was sand-milled, dispersed and standardized, and then spray-dried to obtain a disperse dye.

[0054] The preparation methods of the embodiments and comparative examples are all based on Example 1, and the specific formula is shown in Table 1 below:

[0055] Table 1 Recipe table

[0056]

[0057] It should be noted that the composite liquid additive is self-made, and includes 30-50% polyethylene oxide modified polystyrene, 10-30% isopentenyl polyoxyethylene ether, 2-8% butyl ether, and the balance is water, calculated by mass percentage; wherein polyethylene oxide modified polystyrene: (PPVPE0600) is purchased from Xi'an Qiyue Biotechnology Co., Ltd.). The embodiment of this application adopts the scheme: 30% polyethylene oxide modified polystyrene, 20% isopentenyl polyoxyethylene ether, 8% butyl ether, and the balance is water.

[0058] The above liquid additives are only used as examples and should not be construed as limiting the present application. The dye products provided in the present application can also be compounded with other commercially available additives according to actual needs.

[0059] The dyes of the embodiment and the comparative example were subjected to the following dyeing test under the same intensity adjustment:

[0060] The disperse dyes obtained in the examples and the comparative examples were prepared into disperse dye suspensions with a mass percentage concentration of 1% with water, 20 mL of the disperse dye suspension was mixed with 80 mL of water, and the pH of the dye bath was adjusted to 3.5-4.5 with acetic acid. At the same time, 2 grams of polyester fiber or polyester amine fiber were respectively put into the dyeing for high temperature and high pressure dyeing, and the temperature was raised to 130°C within 35 minutes, kept warm for 45 minutes, and then cooled to 80°C.

[0061] Sampling, observing the fabric sample and measuring its sublimation fastness according to ISO - 105 - P01, its washing fastness according to AATCC61 - 2A, its rubbing fastness according to ISO - 105 - X12, its perspiration fastness according to GB / T3922 - 2013, and its cross - dyeing fastness (white - rubbing fastness) according to BG / T31127 - 2014.

[0062] The water - immersion fastness was tested by the washing method: Weigh the ECE standard detergent with a balance, prepare 1L of washing solution by mixing it with tertiary water (meeting GB / T6682), and preheat it to (40 ± 2)°C for standby. Put the fabric sample and the preheated washing solution into the washing cup at a liquor ratio of 50∶1, load it into the test device and run it at a temperature of (100 ± 2)°C for 5 min. After the washing is completed, take out the fabric sample and keep the residual liquid for evaluation. Use the staining grey scale (meeting GB / T251) to evaluate the fastness grade of the residual liquid of the fabric sample. The results are shown in Table 2:

[0063] Table 2 Test Results (Polyester Fiber)

[0064]

[0065] According to the results in Table 2, it is obvious that under the condition of no reduction cleaning, the fastness of each item in the examples is significantly better than that in Comparative Example 1, generally 0.5 - 1 grade higher; after the comparative example is reduced and washed once, when compared with the examples, the fastness of each item is the same, and some indicators still have advantages.

[0067] As can be seen from Table 2, the disperse dyes provided by this application can directly replace the market - conventional high - washing dark green B and WECT products, can obtain the same depth and compounding effect, have good build - up property. Without reduction cleaning after dyeing, the sublimation fastness, rubbing fastness, perspiration fastness and washing fastness of the dyes are generally 0.5 - 1 grade higher than those of dark green B and WECT, greatly improving the application performance of the dyed fibers and promoting the progress of the industry.

[0068] The disperse dye composition provided by the present application enables fiber to be free from reductive cleaning and has high-temperature (above 170 °C) setting performance, which has remarkable effects on energy conservation, emission reduction, quality improvement and efficiency enhancement in dyeing factories.
