Description
Technical field
The present invention relates to fine chemistry industry and technical field of textile printing, relate in particular to class bis-azo type dispersed dye and an application thereof.
Background technology
The bis-azo type dispersed dye account for 10% left and right of dispersed dye, it is yellow, orange, red, purple, blue etc. that kind mostly is, commonly DISPERSE YELLOW 23 and DISPERSE ORANGE 30 200 29, wherein DISPERSE YELLOW 23 is one of low temperature three primary colors commonly used, coloured light is rich and gaudy, and application performance is good, can under weak basic condition, dye, but easily decomposite P-aminoazobenzene, be put into the forbidding dyestuff; Rich and gaudy, the every fastness of DISPERSE ORANGE 30 200 29 coloured light is better, and the good especially pH of dyeing interdependence wide ranges can be painted under weak basic condition.DISPERSE YELLOW 23 and DISPERSE ORANGE 30 200 29 structures are as follows:
In recent years, demand along with dyeing energy-saving and emission-reduction development, the trevira Dyeing in Alkali Bath has appearred being applicable to, the dispersed dye of pre-treatment, the bath single stage method that dyes, structure as shown in patent CN101649129B, CN101265369B, CN102660146B, CN101284800B, CN102746713B, CN101143969B, CN102618080B, these structures are the monoazo type disperse dye mostly.Dispersed dye described in patent have strong basicity resisting or possess strong basicity resisting and scale resistance simultaneously, be applicable to trevira, polyester superfine fibre alkali bath and pre-treatment, one-pass bath method for dyeing dyeing, also be applicable to the short flow process dyeing of polyester/cellulose fiber blended fabric, can solve the obstinate colouring problems such as the pre-treatment of long-term puzzlement trevira is insufficient, oligopolymer is separated out, bring the cloth cover of fabric clean and tidy simultaneously, style is good, the effect of good hand touch.
Alkali-proof dispersed dye in above-mentioned these patents, wherein the Yellow disperse dye structural formula mostly is the monoazo phenyl amines, also has Anthraquinones as solvent yellow 16 3; The orange disperse dye structural formula is the monoazo class, and similar is in DISPERSE ORANGE 30 200 288 shown in patent CN101812248B and DISPERSE ORANGE 30 200 30:2; Red disperse dyes structural formula benzothiazole monoazo class, similar is in Red-1 200 45 and Red-1 200 53; The blue disperse dye structural formula is benzothiazole or benzisothiazole monoazo class, and similar is in EX-SF DISPERSE BLUE EX-SF 300 148 and EX-SF DISPERSE BLUE EX-SF 300 367.In the above structure containing groups such as the cyano group that directly is connected with phenyl ring, ester group, amide group, carbonyls.Other form and aspect are composite and obtain by these dyestuffs.
The dispersed dye of tetrazo class are also many research so far, red, bright red, the bright red of tetrazo structure, carbuncle dispersed dye as shown in patent GB2095272B, CA914161B, US3712882B, its distillation, Exposure to Sunlight, washing fastness are all better, but alkali resistance is not good; The Huang of tetrazo structure and orange disperse dye shown in patent GB1329745B, GB1322595B, GB998705B, its similar, in DISPERSE YELLOW 23, easily decomposites P-aminoazobenzene; Yellowish-brown, reddish brown, the pad-dry-cure dyeing that orange disperse dye is applicable to polyester-cotton fabric of the structure of tetrazo shown in patent US3904596A; The dyestuff that disperses such as golden yellow, yellow, reddish brown and orange of tetrazo structure shown in patent GB1099097B, GB1020299B, GB1387811B, GB1533121B, its distillation, Exposure to Sunlight, washing fastness are all better, because containing the groups such as hydroxyl, alkoxyl group, amide group in its structure, be not suitable for dyeing under alkaline condition; The indigo plant of the structure of tetrazo shown in patent GB1334006B and dark blue dispersed dye, be applicable to the dyeing of polyester cotton, has certain alkali resistance; The blueness of the structure of tetrazo shown in patent GB2088890B fall apart dye sublimation, Exposure to Sunlight, better, the wide pH scope of washing fastness, good enhancing, reducing resistance; Announced the tetrazo dispersed dye of three kinds of general formulas in patent EP0624683B1, and clearly proposed to dye under the alkaline condition of buffer system, the pH scope is at 8-11.Patent US4398913A research is applicable to the dispersed dye of alkaline discharge printing, and wherein coloured part (being alkali-proof dispersed dye) is announced the dispersed dye of following two tetrazo structures.
