preparation example Construction

[0056] The synthesis method of dye I-1 includes the following steps:

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

[0058] After the reaction is complete, add the material liquid to 500 parts of ice water, add about 10% sodium chloride to salt 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 fibers. Background technique [0002] The present invention aims to develop a blue acid dye composition with bright color, excellent dyeing performance and good dye fastness, which can be used for dyeing applications of nylon fibers, wool fibers and cellulose fibers. [0003] The inventor noticed that in the 1990s, Ciba Specialty Chemicals Company disclosed active groups suitable for dyeing natural or synthetic polyamide fibers in patents. They are: α, β-dihalopropionylamino (NHCOCHBrCH2Br) and α-haloacryloylamino (NHCOCBrCH2). The subsequent application of dyes proved that the above-mentioned active groups are very effective for dyeing natural or synthetic polyamide fibers. [0004] In the practice of the present development and research, the inventors have realized that almost all bright blue...
