A kind of red disperse dye composition

Abstract

The invention discloses a red disperse dye composition, which is characterized by comprising the following components: a dye monomer A with a mass fraction of 60-90%; a dye monomer B with a mass fraction of 8-30%: a mass fraction It is 0.5-10% dye monomer C; wherein: dye monomer A is C.I. disperse red 145, dye monomer B is C.I. disperse red 153, and dye monomer C is C.I. disperse orange 29; the red disperse dye of the present invention, The dye not only has excellent alkali resistance, especially in deep color dyeing, due to the addition of C.I. disperse orange 29, the yellow light will not subside and be reinforced when dyeing dark colors. Under the combined action of yellow light and yellow light, a very deep yellow light-red effect is exhibited. The invention improves the dye depth of the dye and effectively solves the problem of poor color light when the existing red disperse dyes are dyed dark.

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,...

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
