Abstract
The invention relates to a yellow disperse dye capable of dyeing in acid and alkaline baths. The structural formula of the yellow disperse dye is shown in the specification, wherein, R1 is CH3, OCH3, OC2H5 or NHCOCH3; R2 is CH3 or NHCOR3; and R3 is H, CH3 or C2H5. The dye provided by the invention can be used for dyeing and printing of terylene and blended fabrics thereof, and especially is suitable for high-temperature high-pressure dyeing. In weak acid and strong alkaline baths (pH = 4.0-14), the yellow disperse dye can acquire the same dyeing shade and depth, and has good reproducibility and excellent sublimation and washing fastness.
Description
Technical field
The present invention relates to a kind of dispersed dye, specifically relate to all stainable Yellow disperse dye in a kind of acidity or the alkali bath.
Background technology
When adopting high-temperature and high pressure dyeing process that dispersed dye are dyeed, acetic acid commonly used and primary ammonium phosphate are regulated the pH value, and the pH value generally is controlled at 5～6, with guarantee to dye the coloured light of fabric and the circulation ratio of the degree of depth.Especially the dispersed dye of some high washing fastness, its dye bath will be strict controlled in PH=4.0-4.5, otherwise will cause dying to such an extent that the heterochromatic and degree of depth of fabric reduces, and promptly dyeing reproducibility is not good.
Yet polyester piece good dye prefinishing, all under alkaline condition, carry out as processing such as: alkali decrement, concise, destarch, cleaning after the dyeing is also carried out under alkaline condition, and the dyeing that has dispersed dye only needs to carry out in slightly acidic (PH=5-6) is bathed, and brings inconvenience for integral dying technology.Therefore along with the progress of weaving and printing technology, research and develop a kind of can in alkaline dye bath, dyeing and also can guarantee simultaneously that the reproducible dispersed dye of textile dyeing become the important topic that domestic and international printing and dyeing circle need to be resolved hurrily.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can all can stablize dyeing in acidity or alkaline dye bath, the good acid-alkaline of textile dyeing circulation ratio is bathed painted Yellow disperse dye.
For reaching above-mentioned purpose, the present invention has adopted following technical scheme: a kind of acid-alkaline is bathed painted Yellow disperse dye compound, and its general structure is:

A kind of yellow disperse dye composition comprises above-mentioned each or the compound more than.
A kind of yellow disperse dye composition comprises above-mentioned wantonly two or three s' compound.
Acid-alkaline of the present invention is bathed painted Yellow disperse dye, is not subjected to the influence of dye bath acid-basicity during dyeing, is particularly suited for dyeing in alkali bath, makes the realization of the Dyeing in Alkali Bath technology with plurality of advantages become possibility.The front and back that guaranteed overall dyeing and finishing technology connect, and reach the purpose of simplifying technology and energy-saving and emission-reduction.
Acid-alkaline of the present invention is bathed painted Yellow disperse dye, when adopting Dyeing in Alkali Bath, can further remove the grease in the fabric and the residue of destarch, improves dyeing quality; Also can save the acetic acid, lubricant and the oligopolymer that add when weak acid is bathed dyeing and prevent materials such as agent, effectively save cost.
It is gorgeous that acid-alkaline of the present invention is bathed painted Yellow disperse dye coloured light, gives color depth, and have excellent washing and sublimation fastness, and favorable reproducibility can be arranged in pairs or groups with dissimilar dispersed dye, has development prospect widely.
