Problems solved by technology

Among the existing disperse dyes in my country, a considerable number of varieties have poor heat migration resistance, which will make the color fastness of dyed polyester fabrics worse after heat setting or soft, waterproof finishing, such as C.I. Disperse Blue 183 and Disperse Blue EX- SF300% etc.; therefore it is necessary to research and develop a new class of disperse dyes suitable for dyeing polyester and its blended fabrics and having excellent washing fastness, good lifting power and other dyeing properties
The existing document CN101289414 provides a new type of dye compound, which has good performance in washing and sublimation fastness, but there is still room for further improvement

Abstract

The invention provides a disperse blue monomeric compound (I) suitable for hydrophobic fiber material dyeing, its application, and a disperse blue dye made of the monomeric compound as raw material. The disperse dye prepared by the invention can be used for dried powder and particle state supply dyeing by means of liquid state and cream state after fine particalization or spray drying method, etc. By dyeing hydrophobic fiber materials with the disperse dye prepared by the invention, the elevating power is excellent, the pH stability is good, the color yield is high, and especially the sublimation resistance, friction resistance to friction and washing color fastness are excellent. (formula I).

Description

[0001] (1) Technical field [0002] The invention relates to a disperse blue monomer compound suitable for dyeing hydrophobic fiber materials and its application, and a disperse blue dye prepared by using the monomer compound as a raw material. [0003] (2) Background technology [0004] In terms of its color spectrum, the largest output of disperse dyes in my country is blue. With the development of polyester / spandex blended fibers, there is an urgent need in the market for a color fastness to washing, perspiration, and staining when applied to polyester and spandex fabrics. Dyeing rate, lifting power and other dyeing properties are consistent or have little difference. Especially when dyeing deep shades, such as blue-black dyes that are widely used, people have higher requirements for their dyeing performance and fastness. There are large differences in fastness, especially in terms of washing fastness, the difference can reach one level or above. Among the existing disperse...
