Problems solved by technology

[0005] In the Chinese invention patent No. ZL2005100503745 applied by Runtu Company, a combination plan of C.I. Disperse Red 145, C.I. Disperse Red 153 and C.I. The problem of poor compatibility of Red 50
[0006] In another Chinese invention patent with the patent number ZL 2009100274246, a separate combination of C.I. Disperse Red 145 and C.I. Disperse Red 153 is proposed without adding any other components. This solution proposes to solve the problem of existing red disperse dyes. Synchronization of dyeing rate and alkali resistance

[0028] According to the dye components shown in Table 1, dye monomer A, dye monomer B, dye monomer C, and auxiliary agents are blended with water, ground and dispersed with a sand mill, and then spray-dried to obtain a composite medium-temperature disperse red dye. Wherein the composition of A is the commercially available C.I. Disperse Red 145 dyestuff, the composition of B is the commercially available C.I. Disperse Red 153 dyestuff, the composition of C is the commercially available C.I. Disperse Orange 29 dyestuff, and the auxiliary agent selects the commercially available dispersant MF or sodium lignosulfonate or a mixture of both.

Abstract

The invention discloses a red disperse dye composition, which is characterized by being prepared from the following components in percentage by mass: 60-90 percent of a dye monomer A, 8-30 percent ofa dye monomer B, and 0.5-10 percent of a dye monomer C, wherein the dye monomer A is C.I. Disperse red 145, the dye monomer B is C.I. Disperse red 153, and the dye monomer C is C.I. Disperse orange 29. The red disperse dye provided by the invention not only has excellent alkali resistance, but also does not fade and can be reinforced due to the addition of C.I. Disperse orange 29 when deep color dyeing is carried out, and has a very deep yellow light red effect due to the combined action of red, blue and yellow light. According to the invention, the deep dyeing property of the dye is improved,and the problem of poor color light during the deep dyeing of the existing red disperse dye is effectively solved.

Description

Technical field: [0001] The invention relates to a disperse dye, in particular to a red disperse dye composition for replacing C.I. disperse red 167. Background technique: [0002] At present, C.I. Disperse Red 167 is the main red dye in the market. Since the dyeing pH of C.I. Disperse Red 167 is 4~5, the problem of C.I. . [0003] At present, the red dyes blended by various dye companies are based on C.I. Disperse Red 145 and C.I. Disperse Red 153 as the basic components, and then combined with other components to obtain red disperse dyes with different shades and dyeing properties, such as: [0004] In the Chinese invention patent No. ZL2004100257869 applied by Longsheng Company, a combination scheme of C.I. Disperse Red 145 and C.I. Disperse Red 50 is proposed, which can solve the problems of inconsistent color and light and color fastness. [0005] In the Chinese invention patent No. ZL2005100503745 applied by Runtu Company, a combination plan of C.I. Disperse Red 145,...
