Composite disperse dye of the present invention by aforementioned specific blending ratio preparation, can obtain black tone, dyes by ways customary in the industry, can obtain that form and aspect are full, fastness to rubbing good, color rendering is good, the dyeing and weaving thing of environmental protection and economy.
The dye composition of formula used in the present invention (I)~formula V can be synthetic by mode well known to those skilled in the art easily, and wherein component A also can also can adopt the commercial goods with reference to the method preparation of introducing among the patent CN1208057; B component can also can adopt the commercial goods according to the method preparation of introducing among patent JP61019664, the JP11158402; Component C can also can adopt the commercial goods according to the method preparation of introducing among the patent US4904796; Component D can also can adopt the commercial goods according to the method preparation of introducing among the patent US5550217; Component E can also can adopt the commercial goods according to the method preparation of introducing among the patent CN1195003.
Because the singularity of dye industry is difficult to also there is no need to make pure product, can have the impurity in some preparation process usually, also allows to contain the physics impurity of a spot of moisture and trace when dye composite of the present invention is made finished product.
Composite black disperse dye of the present invention generally needs to add auxiliary agent and disperses during application.After for example with structural formula (I), (II), (III) and (IV) represented former dyestuff mixes by above-mentioned proportioning, in the presence of auxiliary agent, water or other wetting agent, carry out corpusculed with pulverizers such as sand mill or shredders; In addition also can with structural formula (I), (II), (III) and (IV) represented former dyestuff in the presence of auxiliary agent, water or other wetting agent, carry out corpusculed with pulverizers such as sand mill or shredders respectively and handle the back and mix with above-mentioned ratio.Usually, auxiliary agent is 0.8-5 with the ratio of former dyestuff weight: 1.In addition, also can directly buy each commercial dye from the market and do assembly.
Described auxiliary agent is dispersed dye dispersion agent commonly used, diffusants etc. when composite, one of preferred following or its several mixture arbitrarily: anionic dispersing agents such as naphthalene sulfonic acidformaldehyde condensation product, alkyl naphthalene sulfonic acid formaldehyde condensation products, benzyl naphthalene sulfonic formaldehyde condensation compound, sulfonated lignin.Particularly, naphthalene sulfonic acidformaldehyde condensation product such as dispersing agent NNO, alkyl naphthalene sulfonic acid formaldehyde condensation products such as Dispersant MF (condensation compound of methyl naphthalene sulfonic acid and formaldehyde), benzyl naphthalene sulfonic formaldehyde condensation compound such as dispersing agent CNF etc., sulfonated lignin such as sodium lignosulfonate (as commercial dispersants Reax83A, Reax85A) etc.
Composite black disperse dye of the present invention can adopt common dip method to dye, and also can be used for direct printing.Wherein, common dip method is put into dye vat and is contaminated as polyester textile is carried out pre-treatment, dyes completely, and cold water cleans to neutral, and strand is done, and carries out reduction clearing again, oven dry; Direct printing is as dying pre-treatment with fabric, oven dry, and setting at printing machine seal dispersed dye mill base, is evaporated again, utilizes the decatize mode to make dye fixing on the fabric, washing at last, stentering forming.
Composite black disperse dye of the present invention, the liquid state after can corpusculed, emulsifiable paste attitude or with spray-drying process etc. carry out dried powdery, graininess is supplied with dyeing.When dying hydrophobic fiber material on the composite disperse dye of the present invention, by adjusting proportion among different, can obtain to have that coloured light is gorgeous, fastness to rubbing reaches the good black dyeing and weaving thing of color well, be the good composite black disperse dye of dyeing behavior of a economic environmental protection.
