Embodiment 1

[0182] Color fastness to soaping

[0183] The color fastness to soaping of the following dyes was determined according to the above method, and the test results are recorded in Table 2.

[0184] Table 2

[0185]

[0186] It can be seen from Table 2:

[0187] The dye compound of the general formula (2) of the present invention has more excellent fastness to washing.

[0188] Two, application performance examples

[0189] Various test methods of the embodiment

[0190] The performance of this embodiment is tested according to the following test methods

[0191] 1. Solubility: Weigh a certain amount of dye into a 250ml beaker, add 100ml of 80℃ hot water, stir with a mechanical stirrer for 5 minutes, and then perform suction filtration (for suction filtration, pressure 0.075Mpa, 5A qualitative filter paper), and observe The filter paper remains. Reduce the dye concentration (G / L) until no dye remains on the filter paper. The dye concentration (G / L) at this time is the solubility of the dye. ...

Embodiment 3

[0209] Nylon dye exhaustion rate determination

[0210] Determine the exhaustion rate of the following dyes according to the above method, and record the test results in Table 5.

[0211] table 5

[0212]

[0213]

[0214] It can be seen from Table 5:

[0215] The anthraquinone blue acid dye composition of the present invention has an excellent dye exhaustion rate.

Embodiment 4

[0217] Fastness to chlorinated water

[0218] Determine the color fastness to chlorinated water of the following dyes according to the above method, and record the test results in Table 6.

[0219] Table 6

[0220]

[0221] It can be seen from Table 6:

[0222] The anthraquinone blue acid dye composition of the present invention still has excellent fastness to chlorinated water.

Abstract

The invention provides an anthraquinone blue acid dye composition which comprises one or more dye compounds selected from the dye compounds represented by general formula (1) and one or more dye compounds selected from the dye compounds represented by general formula (2). The anthraquinone blue acid dye composition provided by the invention has flamboyant color light, and excellent fastness. Compared with the dyes represented by general formula (1), the water washing fastness of the anthraquinone blue acid dye composition is greatly improved. The anthraquinone blue acid dye composition provided by the invention is successfully applied in dying practices of protein fibers, polyamide fibers and blended products of protein fibers and polyamide fibers. The general formula (1) and the general formula (2) are shown.

Description

Technical field [0001] The invention relates to an anthraquinone type blue acid dye composition and its dyeing application on fiber materials. Specifically, the present invention relates to an anthraquinone type blue acid dye composition and its dyeing application on protein fibers and polyamide fibers. Background technique [0002] The invention aims to develop an anthraquinone type blue acid dye composition for dyeing protein fibers and polyamide fibers with bright color, excellent dyeing performance and good dye fastness. It is rare that blue acid dyes or their combinations are used for protein fibers and polyamide fibers with the above-mentioned excellent dyeing properties. [0003] The current anthraquinone blue acid dyes mostly use bromamine acid as the starting material. Among them, the well-known quality is C.I. Acid Blue 277. This variety was developed as early as the 1970s. This variety is easy to synthesize and has certain dyeing performance characteristics. It is fa...
