Abstract
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 blue to black disperse dye composition, be applicable to the printing and dyeing of hydrophobic fiber material or alkaline burnt-out printing process.
(2) background technology
At present, the dyeing of trevira, usually adopts dispersed dye to dye under mildly acidic conditions, but the refining of trevira before dyeing, Alkali reduction, and soap boiling after dyeing and reduction clearing are carried out all in the basic conditions.Therefore, easily cause dyeing uneven when dyeing in acid bath, dye bath pH value fluctuation range is large, and the change of coloured light is large, and reproducibility is poor.
Dispersed dye dye slurry, the finish can effectively removed on polyester textile in the basic conditions, overcome other degradation production separate out in acid bath as polyester oligomer and produce the shortcoming of dye defect, often do not need reduction clearing can meet fastness requirement, and there is the effect that cloth cover is clean and tidy, Fabric Style is good.Many expert's research shows, required by having, generally should control in pH=8.5 ~ 10.0 in dispersed dye basic dyeing to pH value.If pH value < 8.5, the removal of oligopolymer is just abundant not, and the absorption still producing dye product is stain and the contamination of more serious equipment.If pH value > 10.0, then require high especially to the alkali resistance of dyestuff, the kind that can be used for carrying out basic dyeing in existing dispersed dye is just restricted greatly.Therefore, the dispersed dye of the high alkali resistance of research preparation have good market outlook.
High alkali resistance disperse dye and alkaline burnt-out printing process are two prerequisites realizing alkaline etching.Present burn-out printing technique is carry out etching with acid mostly, although sour burn-out printing technics comparing is ripe, burn-out printing product colour is single, does not have mature and stable painted burn-out printing technique.Terylene/spun rayon piece goods, if adopt alkaline burn-out printing technique, while alkali removes regenerated cellulose fibre, if the dispersed dye selected have alkali resistance, then just can not dyeed by the terylene that alkali rots simultaneously.Therefore, the alkaline burn-out printing of terylene/spun rayon piece goods apart from acid burn-out printing style (transparent or semitransparent) outward, the ground colour of burn-out printing part just can present shades of colour, and this is that acid burn-out printing cannot realize.
(3) summary of the invention
The object of the invention is the disperse dye composition providing a kind of blueness to black, its PH interdependence is wider, dye under being not only suitable for conventional acid condition, dye under being also applicable to neutral and alkaline condition, and can be used for terylene alkalescence burnt-out printing process, and one-bath one-step dyeing dyeing can be suitable for separately or together with other reactive dyestuffs, and can good Color be obtained, save the energy, reduce production cost.
