Problems solved by technology

[0006] Although from the point of view of single color dyes, there are still some blue dyes that can meet the standards used in the automotive industry, but once they are used in combination with other compound dyes, problems such as poor application performance often occur, and there are also problems such as high prices.
Most foreign companies use specially synthesized unconventional dyes as special dyes for polyester fibers in automotive interiors, such as the AM-SLR series products of German Destar Company, etc., which are unconventional products with unpublished structural formulas, and because they are economical in civilian products Low reliability, no other manufacturers produce, the price is extremely high

Embodiment 1-8

[0062] After mixing the above three dye monomers and auxiliary agents according to the parts by weight listed in Table 1, grind and disperse with a sand mill, and then spray dry to obtain the blue disperse dye composition of the present invention.

[0063] According to the blue composition provided by the present invention, the fiber is colored in a high-temperature and high-pressure dyeing machine under the condition of 130-135° C. by using an aqueous dispersion in a traditional dyeing manner.

[0064] The color fastness of the fibers dyed by the disperse dye composition obtained in Examples 1-8 was tested by the attached test standard, and the results are shown in Table 2.

[0065] The fibers dyed with the disperse dye compositions obtained in Examples 1-8 were tested using the attached light fastness test standard, and the results are shown in Table 3.

Embodiment 9

[0080] The blue dye composition obtained in Example 8 is used in conjunction with yellow dye and red dye to obtain a beige and light gray dye composition, and its weight percentage composition and light fastness test results are listed in Table 7.

[0081] Wherein, the red dye composition is a mixture of 30 parts by weight of Disperse Red 60, 12 parts by weight of Disperse Red 146 and 1 part by weight of Disperse Red 92, and the yellow dye composition is 25 parts by weight of Solvent Yellow 163, 4 parts by weight of Disperse Orange 29 and 15 A mixture of disperse yellow 51 in parts by weight. The preparation method is the same as that of the blue dye composition of the present invention. Each dye monomer also adopts the disperse dye of the corresponding color that commercially available product Changzhou Yabang factory produces.

Abstract

The invention discloses a blue disperse dye composition with high light fastness. The blue disperse dye composition comprises at least two of C.I. disperse blue 56, C.I. disperse blue 60 and C.I. disperse blue 77. The disperse dye composition is particularly suitable for dyeing interior fabrics for automobiles, and can meet the dyeing requirement on high light fastness of automotive interiors.

Description

technical field [0001] The invention relates to a blue disperse dye composition with high light fastness, which is especially suitable for dyeing polyester fibers and blended fabrics for automobile interior fabrics. Background technique [0002] In recent years, hydrophobic fiber materials, especially polyester fibers, have been widely used in automotive interior decoration, especially as a material for seat sheets. As the importance of automotive interior styling has increased, there has been a greater demand for richer colors. When used as a sheet for automotive interior decoration, color fading is prone to occur due to long-term high-temperature exposure, and it is difficult to maintain a good color for a long time. Therefore, the dyes used for dyeing automotive fabrics must meet the requirements of light fastness, especially the dyeing fastness to light at high temperature. [0003] Polyester fibers used in automotive fabrics are usually dyed blue using dyes from the a...
