Problems solved by technology

[0002] Traditional reactive blue generally uses C.I reactive blue 19 as the main component. The dye has strong reactivity, poor stability in salt and alkali resistance, high printing and dyeing requirements, easy to dye flowers or appear color spots; the shade is not bright enough to produce redder and brighter colors.

Embodiment 1

[0019] A new type of composite reactive brilliant blue dye, 1 part (mole parts) of 1-amino-4-(5'-amino-2', 4', 6'-trimethylphenylamino) anthraquinone-2,3 '-Disulfonic acid is dissolved into a 25% aqueous solution at PH5.5~7, 40°C, cooled to 0~5°C, and 1.02~1.05 parts of 2,4,6-trifluoro-5-chloropyrimidine is added in 1~2 hours, Simultaneously keep pH6.5~7.5 with 20% soda ash solution, react for 3~4 hours, add hydrochloric acid to adjust pH5.8~6.2, salt out with sodium chloride, press filter, flash dry, obtain active brilliant blue former powder ( MS: [M+H] + =723.00). The dye is red and brilliant blue, low directness, RF value 0.98, solubility (50°C) 100g / l, 1 / 1 dyeing depth. Fastness indicators: light fastness level 6, washing fastness level 4, ironing fastness Grade 4, dry friction grade 4~5, wet rubbing fastness grade 4, chlorine immersion fastness grade 3~4.

[0020] The former powder of reactive brilliant blue and C.I. reactive blue 220 are prepared by the above method,...

Embodiment 2

[0022] Reactive brilliant blue raw powder and C.I. reactive blue 220 raw powder were prepared by the above method, Yuanming powder was mixed according to the mass-weight ratio of 80:10:10, and 2% of dustproof agent FC-3 was added to standardize to obtain commercial products.

Embodiment 3

[0024] Reactive Brilliant Blue former powder and C.I. Reactive Blue 220 former powder are obtained by the above method, sodium lignosulfonate is mixed according to the mass-weight ratio of 75:10:15, and 2% of dustproof agent FC-3 is added, standardized to obtain commodity.

Abstract

The invention discloses a complex active brilliant blue dye which is characterized by comprising the active components of a brilliant blue dye shown in formula I and C. I. reactive blue 220 in the weight ratio of (60-80): (10-25). The novel complex active brilliant blue dye can be applied to the dip dyeing process at 50-60 DEG C, continuous pad dyeing process and printing process, has a substantivity Rf value of 0.9, moderate reactivity and saline and alkali tolerance, and is also applicable to cold pad-batch dyeing. The colored light controllability is good, the dyeing lifting force is good, the product solubility is more than 150g / l at 20 DEG C, and the product performance is superior to that of the traditional reactive brilliant blue dye.

Description

technical field [0001] The invention belongs to the technical field of dyes, in particular to a novel composite reactive brilliant blue, and simultaneously provides a method for manufacturing the brilliant blue dye. Background technique [0002] Traditional reactive blue generally uses C.I reactive blue 19 as the main component. The dye has strong reactivity, poor stability in salt and alkali resistance, high printing and dyeing requirements, and is easy to dye flowers or appear color spots; the shade is not bright enough to produce redder and brighter colors. Contents of the invention [0003] The purpose of the present invention is to provide a new type of composite brilliant blue for the current printing and dyeing industry technical requirements of high strength, high solubility, deep color dyeing, bright shade, good dyeing controllability, clean production, energy saving and emission reduction. dye. The dye has bright shade, high solubility, especially good solubilit...
