Embodiment 1

[0057] Composite target:

[0058]

[0059] Raw materials include m-nitroaniline, epichlorohydrin, aniline, benzyltriethylammonium chloride, hydrochloric acid, sodium nitrite, etc.

[0060] Preparation of coupling components: 148.56g of 100% epichlorohydrin, 18.63g of aniline with a purity of 100% and 0.36g of benzyltriethylammonium chloride were sequentially added into a coupling reaction kettle, and stirred until completely dissolved. After keeping the reaction at room temperature for 36 hours, the excess epichlorohydrin was evaporated by rotary evaporation, and a taupe viscous substance was formed. Add 50ml of 30% acetic acid and stir until completely dissolved for use.

[0061] Diazotization reaction: Add 27.6g of 100% m-nitroaniline, 500ml of water and 50ml of 36% hydrochloric acid to the diazotization reaction kettle and heat and stir until completely dissolved. Add 47.33g of 30% sodium nitrite solution dropwise, maintain the diazotization reaction at 0-5°C and normal...

Embodiment 2

[0067] Composite target:

[0068]

[0069] Raw materials include p-nitroaniline, epichlorohydrin, 3-amino-4-methoxyacetanilide, benzyltriethylammonium chloride, hydrochloric acid, sodium nitrite, etc.

[0070] Preparation of coupling components: Add 148.56g of 100% epichlorohydrin, 36g of 100% 3-amino-4-methoxyacetanilide and 0.72g of benzyltriethylammonium chloride in the coupling reaction kettle, Stir until completely dissolved. After keeping the reaction at room temperature for 36 hours, the excess epichlorohydrin was evaporated by rotary evaporation, and a dark gray-brown sticky substance was formed. Add 50ml of 30% acetic acid and stir until completely dissolved for use.

[0071] Diazotization reaction: Add 27.6g of 100% m-nitroaniline, 500ml of water and 50ml of 36% hydrochloric acid to the diazotization reaction kettle and heat and stir until completely dissolved. Add 47.33g of 30% sodium nitrite solution dropwise, maintain the diazotization reaction at 0-5°C and n...

Embodiment 3

[0077] Composite target:

[0078]

[0079] Raw materials include 2-bromo-4,6-dinitro-aniline, epichlorohydrin, m-acetanilide, benzyltriethylammonium chloride, sulfuric acid and nitrosyl sulfuric acid, etc.

[0080] Preparation of coupling components: 148.56g of 100% epichlorohydrin, 30g of 100% pure m-acetanilide and 0.6g of benzyltriethylammonium chloride were successively added into the coupling reaction kettle, and stirred until completely dissolved. After keeping the reaction at room temperature for 36 hours, the excess epichlorohydrin was evaporated by rotary evaporation, and a taupe viscous substance was formed. Add 50ml of 30% acetic acid and stir until completely dissolved for use.

[0081]Diazotization reaction: Add 52.404g 100% 2-bromo-4,6-dinitro-aniline and 103.6g 98% sulfuric acid to the diazotization reaction kettle in turn, stir until completely dissolved at 20-30°C, then slowly add 63.5g of 40% nitrosyl sulfuric acid, heat up to 50-55°C and keep it warm for...

Abstract

The invention relates to a crosslinkable active disperse dye compound as well as a preparation method and application thereof. A structural formula of the disperse dye compound is one or more as shown in the specification. The preparation method of the crosslinkable active disperse dye compound comprises the following steps: preparing coupling components, carrying out diazotization and coupling reaction, wherein amino of aminoaniline-containing compounds in the synthesized compound structure is substituted by an active group which is 3-chloro-2-hydroxypropyl, and the substituent group can be formed into a crosslinkable epoxy ethyl active group under an alkaline condition. The crosslinkable active disperse dye compound is applied to inkjet ink. The crosslinkable active disperse dye compound is capable of printing on polyester fibers and cotton fibers at the same time, and prepared into inkjet ink for being applied to printing of blended fabrics such as polyester cotton, so that the defect that the cotton-polyester blended fabric paint is poor in hand feeling during printing, poor in washing fastness, long in mixed dye printing process flow and severe in mutual-staining of dyes is solved.

Description

technical field [0001] The present invention is a divisional application with the application number 201410397890.4, the title of the invention: a crosslinkable reactive disperse dye compound and its preparation and application, and the filing date is August 13, 2014. Background technique [0002] With the rapid development of computer technology in the field of textiles, the application fields of inkjet printing technology are mainly expanded into the following three aspects: desktop jet printing, inkjet jet printing and fabric jet printing. The purpose of inkjet printing of fabrics is to replace the traditional printing technology: because inkjet printing equipment can be used in conjunction with a computer, image design, sample scaling and printing can be combined to meet short-process, small-batch, and multi-variety requirements. On request, even custom graphics can be done. Especially with the continuous update of inkjet printing equipment, the continuous improvement o...
