Description
Technical field
The present invention relates to a kind of reactive dye compositions and the tint applications on filamentary material thereof.Particularly, the present invention relates to navy blue reactive dye composition and the tint applications on filamentary material thereof.
Background technology
Triphendioxazine type reactive dyestuffs are continue the new color system of Application and Development after prevailing anthraquinone type reactive dyestuffs in blue active dye for many years.
The coloring intensity of triphendioxazine type reactive dyestuffs, higher than anthraquinone type and azo reactive dye, is 4-6 times of anthraquinone type, and coloured light vividness and anthraquinone type approach, and fiber is had to very high substantivity.
The triphendioxazine precursor structure, for plane, linear ring more than five yuan, be orange.Introduce amino or substituent amino to precursor structure, be blue.As introduce hydroxyl or alkoxyl group, take on a red color.These groups of introducing generally double as the abutment of active group simultaneously.
The triphendioxazine blue active dye is dye wherein with fastest developing speed.External each major company, as the companies such as Bayer, Hoechst, Sumitomo, vapour bar, De Sida are all competitively delivering numerous patents aspect the new variety of this class blue active dye of exploitation.
The characteristics of triphendioxazine type blue active dye are bright-coloured, the excellent every fastness of coloured light and good dyeability.The development research of current these class blue active dye new variety mainly concentrates on and improves degree of fixation, adapts to low salt dyeing, improves level-dyeing property and consistency and improve fastness to chlorine-bleaching and light fastness.It should be noted that the chemosynthesis complexity of triphendioxazine type blue active dye.Wherein the oxidation ring-closure reaction is essential step.Reaction not only relates to the purity of product but also affects the vividness of dyestuff.The spent acid that reaction produces has a strong impact on environmental protection.This is also the focus of each major company's research and development.
Another approach that improves the defect of triphendioxazine type blue active dye be adopt with the same color and luster of other type or heterochromatic damp reactive dyestuffs carry out composite, to learning from other's strong points to offset one's weaknesses, reduce the cost, the broadened application scope, give full play to its characteristics.
The patent that external each major company delivers aspect composite has:
