Description

Technical Field

[0002] In recent years, high-water-washing color fastness disperse dyes for polyester microfibers and synthetic fibers have become a research and development hotspot in the dye industry. However, the high-fastness disperse dyes currently on the market generally have the characteristics of poor color yield, poor dye sublimation fastness, serious dye staining (floating color) (requiring reduction washing), or not resistant to high temperature (above 170 degrees Celsius) setting, and are relatively expensive, which cannot fully meet customer and market needs. For example, some existing high-fastness dyes have good color yield, but poor water fastness, need reduction washing after dyeing, and are not resistant to high temperature setting; for example, some existing high-fastness dyes have a wide dyeing pH range, high temperature resistance, no reduction washing after dyeing, and good water fastness, but the color yield is about 20-30% lower and the dyeing levelness is poor.

DETAILED DESCRIPTION

[0020] The embodiments of the present application will be described in detail below in conjunction with specific examples, but it will be appreciated by those skilled in the art that the following examples are only used to illustrate the present application and should not be considered as limiting the scope of the present application. If specific conditions are not specified in the examples, they are carried out according to normal conditions or the conditions recommended by the manufacturer. If the manufacturer is not specified for the reagents or instruments used, they are all conventional products that can be purchased commercially.

[0021] The dye monomer compounds used in the examples are all existing dyes, and the preparation methods can refer to CN113563737A, CN118703057 A, etc.

[0022] Example 1 A disperse dye composition was prepared by compounding 7.9 g of compound A-1 and 11.5 g of compound B-1, and then adding 70.6 g of dispersant MF, 10 g of lignin and an appropriate amount of water. The mixture was sand-milled, dispersed and standardized, and spray-dried to obtain a disperse dye.

[0023] 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: Table 1 Recipe

[0024] It should be noted that the composite liquid additive is homemade, 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 the present application adopts a scheme: 30% polyethylene oxide modified polystyrene, 20% isopentenyl polyoxyethylene ether, 8% butyl ether, and the balance is water.

[0025] The above liquid additives are only used as examples and should not be construed as limiting the present application. The dye product provided in the present application can also be compounded with other commercially available additives according to actual needs.

[0026] The dyes of the embodiment and the comparative example were subjected to the following dyeing test under the same intensity adjustment: The disperse dye obtained in the example and the dye of the comparative example were prepared into disperse dye suspensions with a mass percentage concentration of 1% with water, 20 mL of the disperse dye suspension was taken and mixed with 80 mL of water, and the pH value 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 mixture for high temperature and high pressure dyeing, the temperature was raised to 130° C. within 35 minutes, kept warm for 45 minutes, and then cooled to 80° C.

[0027] Take samples, observe the fabric samples, and measure their sublimation fastness using ISO-105-P01, their washing fastness using AATCC61-2A, their rubbing fastness using ISO-105-X12, their perspiration fastness using GB / T3922-2013, and their splicing mutual coloring fastness (white impact fastness) using BG / T31127-2014.

[0028] The water fastness is tested by washing method: weigh the ECE standard detergent on a balance, mix it with grade 3 water (in accordance with GB / T6682) to make 1L of washing liquid, and preheat it to (40±2)℃ for use. Put the fabric sample and the preheated washing liquid into the washing cup at a bath ratio of 50:1, put it into the test device and run it at (100±2)℃ for 5 minutes. After washing, take out the fabric sample and keep the residual liquid for evaluation. Use the staining gray card (in accordance with GB / T251) to evaluate the residual liquid fastness grade of the fabric sample. The results are shown in Table 2: Table 2 Test results (polyester fiber)

[0029] According to the results in Table 2, it is obvious that under the condition of non-reduction cleaning, the fastness of the embodiment is significantly superior to that of the comparative example 1, generally 0.5-1 level higher; after the comparative example is reduced and washed once, the fastness of the embodiment is consistent with that of the comparative example, and some indicators have advantages.

[0030] Figure 1 The experimental photos of the washing fastness, sublimation fastness and perspiration fastness of the dyes obtained in Example 1, Example 5 and Comparative Example 1; Figure 2 The experimental photos of the white fastness, water fastness and rubbing fastness of the dyes obtained in Example 1, Example 5 and Comparative Example 1; Figure 3 The experimental photos of the washing fastness, sublimation fastness and perspiration fastness of the dyes obtained in Example 7, Example 12 and Comparative Example 2; Figure 4 These are experimental photographs of the white fastness, water fastness and rubbing fastness of the dyes obtained in Example 7, Example 12 and Comparative Example 2.

[0031] It can be seen from Table 2 that the disperse dyes provided by the present application can directly replace the conventional high-water-washable dark green B and WECT products on the market, and can obtain the same depth and compounding effect, with good lifting power. After dyeing, without reduction cleaning, the sublimation fastness, friction fastness, perspiration fastness, and washing fastness of the dye are generally 0.5-1 level higher than those of dark green B and WECT, which greatly improves the application performance of dyed fibers and promotes industry progress.

[0032] The disperse dye composition provided in the present application is free of reduction cleaning for fibers and is resistant to high temperature (above 170° C.) setting, which has a significant effect on energy conservation and emission reduction, and improving quality and efficiency in dyeing factories.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
