The invention provides a blue-to-black disperse dye composition, which mainly comprises one or multiple blue dye ingredients A shown as the structure formula (I), one or multiple red dye ingredients B shown as the structure formula (II) and one or multiple orange dye ingredients C shown as the structure formula (III). The disperse dye composition has the advantages that the dying bottleneck of the existing ordinary disperse dye under the alkaline condition is broken through, the problems of white powder, color points and dyeing defect generation caused by the dyeing under the acid condition, the contamination on the inner wall of dyeing equipment caused by low polymers, and the like are solved, the dyeing quality is effectively improved, the stability and the reproducibility of the process are ensured, and the once success rate of the dyeing is improved. In addition, the prepared disperse dye has higher alkali resistance capability and can be applied to an alkali burnt-out process, the defect of single acid burnt-out color is overcome, and the requirements of the society on the aesthetic perception and the variety on clothing and decorations are met.
Description
(1) technical field
The present invention relates to a kind of blueness to black disperse dye composition, be applicable to the printing and dyeing or the alkaline burnt-out printing process of hydrophobic fiber material.
(2) background technology
At present, the dyeing of trevira adopts dispersed dye under solutions of weak acidity, to dye usually, but refining, the alkali decrement of trevira before dyeing, and soap boiling and reduction clearing after the dyeing are all carried out under alkaline condition.Therefore, be prone to cause that dyeing is uneven when dyeing in the acid bath, dye bath pH value fluctuation range is big, and the variation of coloured light is big, the dyeing poor reproducibility.
Slurry, finish on the polyester textile can be effectively removed in dispersed dye dyeing under alkaline condition; Overcoming other degradation production such as polyester oligomer separates out in acid bath and produces the shortcoming of dying defect; Often do not need reduction clearing can satisfy the fastness requirement, and have the effect that cloth cover is clean and tidy, Fabric Style is good.Many expert's research shows, to the requirement to some extent of pH value, generally should be controlled at pH=8.5 ~ 10.0 in the dispersed dye basic dyeing.If pH value＜8.5, the removal of oligopolymer is just abundant inadequately, and still the absorption contamination of article and more serious equipment contamination are dyed in generation.If pH value＞10.0 then require highly especially to the alkali resistance of dyestuff, the kind that in existing dispersed dye, can be used for carrying out basic dyeing just is restricted greatly.Therefore, the high alkali-proof dispersed dye of research preparation have good market outlook.
High alkali resistance disperse dye and alkaline burnt-out printing process are two prerequisites that realize alkaline etching.Burnt out printing technology is to carry out etching with acid mostly now, though sour burnt out printing technology comparative maturity, the burnt out printing product colour is single, does not have mature and stable painted burnt out printing technology.Terylene/spun rayon piece goods if can adopt alkaline burnt out printing technology, and when alkali was removed regenerated cellulose fibre, if the dispersed dye of selecting have alkali resistance, the terylene that is not then rotted by alkali just can dye simultaneously.Therefore, the alkaline burnt out printing of terylene/spun rayon piece goods is except that the style that acid burnt out printing is arranged (transparent or semitransparent), and the ground colour of burnt out printing part just can demonstrate shades of colour, and this is that acid burnt out printing can't realize.
(3) summary of the invention
The object of the invention is to provide the disperse dye composition of a kind of blueness to black, and its PH interdependence is wider, not only is suitable for the dyeing down of conventional acidic conditions; Also be applicable to neutral and alkaline condition dyeing down; And can be used for terylene alkalescence burnt-out printing process, and can be suitable for a bath single stage method dyeing separately or with other reactive dyestuffs, and can obtain good Color; Practice thrift the energy, reduced production cost.
The technical scheme that the present invention adopts is:
