Problems solved by technology

[0006] Although there are foreign countries that specially synthesize unconventional dyes as special dyes for polyester fibers for automobiles, such as the AM-SLR series products of DyStar Dyestuffs Germany Co., Ltd., their specific ingredients are not disclosed, and their prices are relatively high. Low economy in civilian products such as

Embodiment 1-6

[0043] Take 1-20 parts of C.I. Disperse Red 60, 2-50 parts of C.I. Disperse Blue 60, 1-40 parts of C.I. Disperse Blue 56, 1-20 parts of C.I. Disperse Red 167 and 2-50 parts of C.I. Disperse Orange 29, and mix them; Add 2-20 parts of additives, 10-100 parts of water and 1-10 parts of ethanol, fully disperse by sanding; spray dry the sanded mixture, and evenly spray 5-30 parts of dust-proof oil and 0.5-5 part of light fastness improving agent to obtain the disperse dye composition described in the application, and its particle size was detected to be 0.1 μm to 2 μm.

[0044] See Table 2 for each component and its usage amount in Examples 1-6.

[0045] Each component and usage amount thereof (unit: part) in table 2 embodiment 1-6

[0046]

Embodiment 7-12

[0048] Step 1, the disperse dye composition prepared by embodiment 1-6 is prepared into the disperse dye suspension that concentration is 1.0-2.0g / 500mL with deionized water respectively (note: the disperse dye consumption here is listed in Table 3 Indicated by m);

[0049] Step 2, take 20mL of uniformly dispersed disperse dye suspension, add 80-130mL deionized water to mix (Note: In Table 3, the amount of deionized water added here is represented by N, and the amount of disperse dye in this system is represented by C Express), adjust its pH to 4.5-5.0 with acetic acid;

[0050] Step 3, put 2-3g of pre-treated polyester fiber for high-temperature and high-pressure dyeing: heat up to 130°C within 30-60 minutes, keep warm for 30-60 minutes, cool to 55-60°C for sampling, and obtain colored polyester Ester fiber.

[0051] See Table 3 for each component and its consumption in Examples 7-12.

Abstract

The invention discloses a disperse dyestuff composition with high color fastness to sunlight as well as a preparation method and application thereof. The disperse dyestuff composition is prepared from the following components in parts by weight: 1 to 20 parts of C.I. disperse red 60, 2 to 50 parts of C.I. disperse blue 60, 1 to 40 parts of C.I. disperse blue 56, 1 to 20 parts of C.I. disperse red 167 and 2 to 50 parts of C.I. disperse orange 29. The disperse dyestuff composition with high color fastness to sunlight, disclosed by the invention, has considerably high stability and color fastness to the sunlight at a high temperature; particularly, the change of the color fastness to sunlight is relatively small under a long-period illumination condition and the requirement on the color fastness to sunlight of textiles for automobiles can be met.

Description

technical field [0001] The invention belongs to the field of dyes, and more specifically relates to a disperse dye composition with high light fastness, a preparation method and an application thereof. Background technique [0002] Automotive textiles refer to those used in automobiles, including seats, seat covers, armrest coverings, etc. In recent years, polyester fibers have been widely used in automotive textiles. As the importance of style in automotive textiles increases, there is a greater demand for richer colors. Polyester fiber is a hydrophobic fiber, which lacks groups that combine with dyes. Generally, it can only be dyed with non-ionic disperse dyes with small molecular weight, no strong ionic water-soluble groups, and low solubility. The interaction force between polyester fiber and disperse dye is dominated by hydrogen bond and hydrophobic bond force. [0003] Automobile textiles are exposed to high temperature for a long time, and the temperature differenc...
