[0056] The synthetic method of dyestuff I-1 thus comprises the following steps:

[0057] Add 39.4 parts of 1-amino-2-sulfonic acid-4-anilinoanthraquinone into 400 parts of 98% sulfuric acid, stir to dissolve, cool down to 5-10°C, keep the temperature below 10°C, add 40 parts of formaldehyde solution dropwise, Stir for 3h to complete the reaction.

[0058] After the reaction is complete, add the feed liquid to 500 parts of ice water, add about 10% sodium chloride for salting out, and filter to obtain the dye I-1.

[0059] The synthetic reaction formula is:

Abstract

The invention discloses a blue acidic dye composition and a fiber dyeing application thereof, and relates to an acidic dye composition and a dyeing application thereof. The acidic dye composition comprises one or more of dye compounds represented by the formula (I) and one or more of dye compounds represented by the formula (II); and the weight ratio of the dye compounds represented by the formula(I) to the dye compounds represented by the formula (II) is (40-60) : (60-40). The provided blue acidic dye composition has excellent dyeing rate, leveling property, permeability, and dyeing fastness, and can dye whole socks uniformly.

Description

technical field [0001] The invention relates to an acid dye composition and its dyeing application, more specifically, it relates to a blue acid dye composition and its dyeing application on fiber. Background technique [0002] The invention aims to develop a blue acid dye composition with bright shade, excellent dyeing performance and good color fastness, which can be used for dyeing nylon fibers, wool fibers and cellulose fibers. [0003] The inventor noticed that Ciba Specialty Chemicals disclosed active groups suitable for dyeing natural or synthetic polyamide fibers in patents in the 1990s. These are: α,β-dihalopropionylamino (NHCOCHBrCH2Br) and α-haloacryloylamino (NHCOCBrCH2). The subsequent application of dyes has proved that the above-mentioned active groups are very effective in dyeing natural or synthetic polyamide fibers. [0004] In the practice of this development research, the inventors realized that almost all blue reactive dyes with bright shades are anthr...
