Problems solved by technology

[0003] In the prior art on the market, some researchers improve the dyeing performance of dyes, especially blue disperse dyes, by compounding dyes. However, the effect is not ideal, the color fixation rate is not high, and the color fastness and weather resistance are average. Poor, unable to meet the needs and expectations of the supply and demand market for dyes, for this reason, the development of a dye or compound dye with excellent dyeing performance and high color fixation rate is the main topic of the current dye industry

Embodiment 1-6

[0025] The semi-finished products and additives of component A with structure such as (I), component B with structure such as (IIa) and component C with structure such as (IIIb) are pre-dispersed and crushed by adding water, and then ground and dispersed by grinding. The pipeline is sent to the spray drying tower for drying, and the dustproof agent and dispersant are evenly added at the same time, and finally the finished product is packaged. The specific process is shown in Table 1.

Abstract

The invention discloses a blue disperse dye compound, which belongs to the technical field of fine chemical engineering. The blue disperse dye compound provided in the invention comprises, by mass, 50 to 70% of component A, 6 to 10% of component B and 0.4 to 1.0% of component C, with the balance being auxiliary agents. The blue disperse dye compound has brilliant colored light, good dispersibility and color fastness and superior level-dyeing properties, and is especially applicable to printing and dyeing of terylene and terylene / spandex fabrics.

Description

technical field [0001] The invention relates to a blue disperse dye compound, belonging to the technical field of fine chemicals. Background technique [0002] With the development of polyester fibers, especially the rapid development of polyester / spandex fabrics, people have higher and higher requirements for textiles. Dyes have better application properties and various color fastnesses. [0003] In the prior art on the market, some researchers improve the dyeing performance of dyes, especially blue disperse dyes, by compounding dyes. However, the effect is not ideal, the color fixation rate is not high, and the color fastness and weather resistance are average. Poor, unable to meet the demand and expectation of the supply and demand market for dyes, for this reason, the development of a dye or compound dye with excellent dyeing performance and high color fixation rate is the main topic of the current dye industry. Contents of the invention [0004] The invention provid...
