Embodiment 1～22

[0023] According to the data shown in Table 1, dye monomer A, dye monomer B, dye monomer C, dye monomer D, dye monomer E and methylnaphthalenesulfonic acid formaldehyde condensate (dispersant MF), naphthalenesulfonic acid Formaldehyde condensate (diffusing agent NNO) and sodium lignosulfonate (lignin 85A, 83A) were mixed with water, ground and dispersed with sand mill, and then spray-dried.

[0024] Among them, dye monomer A and dye monomer B can be selected from C.I.DISP BLUE291:3# produced by Zhejiang Runtu Co., Ltd., dye monomer C can be selected from Disperse Orange 298# produced by Zhejiang Runtu Co., Ltd., and dye monomer D C.I.DISPBLUE291#, Disperse Blue 291:5#, Disperse Blue 291:4# produced by Zhejiang Runtu Co., Ltd. can be selected, and DISPBLUE 30:2# produced by Zhejiang Runtu Co., Ltd. can be used as the dye monomer E. Orange 288#.

Abstract

The invention discloses an environmental-friendly disperse dye compound of high fastness series, mainly comprising 5-95 weight portions of the mixture of dye monomers A as shown in formula (1-1) and dye monomers B as shown in formula (1-2), and 5-60 weight portions of dye monomers C as shown in formula (2). The disperse dye compound of the invention has excellent compatibility, wide application range of pH value in dyeing, high upgrading performance, high color yield, good level dyeing property and good color fastness, which is a disperse dye compound with excellent comprehensive performances.

Description

technical field [0001] The invention relates to a disperse dye composition, which is especially suitable for dyeing and printing of polyester and blended fabrics. Background technique [0002] With the recent rapid development of new polyester fibers and the improvement of people's requirements for textiles, correspondingly, higher requirements are put forward for the dyeing performance and environmental protection performance of the dye itself. That is to say, it is required not only to have good lifting power and fastness performance in all aspects, but also to have good environmental protection performance to avoid the impact on the human body and the environment. However, the disperse dye compositions in the prior art cannot or cannot satisfy the two requirements at the same time. SUMMARY OF THE INVENTION [0003] The invention provides a disperse dye composition which is environmentally friendly, economical and excellent in various fastness indexes, especially in ter...
