Embodiment 1～12

[0035] According to the feeding ratio shown in table 1, dye component A, component B, component C and methylnaphthalenesulfonic acid formaldehyde condensation product (dispersant MF), naphthalenesulfonic acid formaldehyde condensation product (diffusion agent NNO) or Sodium lignosulfonate (lignin 83A, 85A), mixed with water, ground and dispersed with a sand mill, and then spray-dried.

[0036] The dye monomers can be commercially available or self-prepared.

[0037] The preparation method of the structural formula (I) is: after diazotization of 2-cyano-4-nitroaniline, it is formed by coupling with m-acetamido-N, N-methoxycarbonylmethyl;

[0038] The preparation method of the structural formula (II-1) is: after diazotization of 2,4-dinitro-6-chloroaniline, it is formed by coupling m-acetylamino-N,N-methoxycarbonylmethyl;

[0039] The preparation method of structural formula (II-2) is: after diazotization of 2,4-dinitro-6-bromoaniline, it is formed by coupling m-acetamido-N,N-m...

Abstract

The invention discloses a disperse bougainvillea dye composition. The weight percentage of raw materials comprises: component A: 1% to 99%, component B: 1% to 99%, component C: 0% to 10%; The component A is the compound shown in the following formula (I), the component B is the compound shown in the formula (II), and the component C is the compound shown in the formula (III). The disperse bouquet red dye composition described in the present invention has excellent compatibility, bright color and light when dyeing, wide application range of pH value, good lifting power, high color yield and good fastness, and is mainly suitable for polyester / spandex Fiber dyeing, and polyester / spandex fibers have particularly high washing fastness and sublimation fastness. It is a disperse dye composition with excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of disperse dyes, in particular to a disperse bordeaux dye composition suitable for polyester fiber printing and dyeing. Background technique [0002] Today, when people are pursuing fashion, the fabric and color of clothing have increasingly become the object of attention. Polyester / spandex is favored by fashionistas because of its comfortable feel and high elasticity. The appearance of maroon in disperse dyes has further opened up people's horizons. Disperse Hongyu 73# was once the most important dye in the dye industry because of its unique maroon shade. However, due to the poor sublimation fastness of Disperse Hongyu 73#, the printing and dyeing performance on polyester / spandex textile fibers cannot meet people's requirements. Therefore, it is an urgent problem to be solved in the printing and dyeing industry to develop a kind of disperse dye with excellent dyeing performance on polyester / spandex fibe...
