A water-based pigment jet ink comprises 1-12wt% of a nanopigment, 1-5wt% of a dispersant, 1-15wt% of a modified polyurethane resin emulsion (solid content), 5-25wt% of a humectant, 5-15wt% of an osmotic agent, 0-2wt% of a surfactant, 0-2wt% of a PH adjusting agent, 0.1-0.5wt% of a sterilization antiseptic, and the balance deionized water. The ink has the advantages of excellent preservation stability and printing smoothness, particle nanometer level, complete chromatogram, substantially increased comprehensive properties comprising the light resistance, the water resistance, the chemical resistance, the scratch resistance, high brightness, the high and low temperature resistances, the ageing resistance and the like, and application range enlargement.

The invention discloses a steam-cleaning free printing process for disperse dye. The steam-cleaning free printing process is characterized by comprising the following steps of: (1) matching the premixed steam-cleaning free printing slurry with the disperse dye and a thickening agent and printing the mixture on fabric in a rotary screen printing machine or a flat screen machine by using a manual printing process according to the conventional process; (2) baking the fabric for 4-10 minutes at the temperature of 110-130DEG C before descending the screen printing machine; and (3) baking and developing while shaping at the temperature of 160-180DEG C and classifying and packaging to form a printed finished product, or carrying out soft padding treatment or functional special treatment, drying,tentering, shaping, classifying and packaging to form the printed finished product. By using the process, the rate of graded products of every 100 meters can be improved by 1-2 percent and the process can be freely compatible with the colors of paint while printing the disperse dye, thereby thoroughly eliminating the pollution of printing sewage and water with color to the environment. The printed finished products have bright color, are transparent, attractive, elegant and luxury and feel soft and smooth.

The invention provides an imidazole-based anionic dye dyeable modified copolyester masterbatch, and preparation and application thereof. The imidazole-based anionic dye dyeable modified copolyester masterbatch is characterized in that a comonomer of the imidazole-based anionic dye dyeable modified copolyester masterbatch comprises terephthalic acid, glycol, N-2-(3,5-dicarboxyl phenyl) ethyl-N'-methylimidazole chlorine salt and 2-methyl-1,4-butanediol according to the molar ratio of 1:1.2-2.5:0.1-0.4:0.03-0.25. The imidazole-based anionic dye dyeable modified copolyester masterbatch prepared by the invention is blended with unmodified PET polyester to obtain a polyester product which has good anionic dye dyeability, the polyester product can be dyed at normal temperature and under normal pressure or can be subjected to boiling dyeing under normal pressure, the dye-uptake can be above 85%, dye cannot leak easily, and the imidazole-based anionic dye dyeable modified copolyester masterbatch can be applied to the field of garment, home textile, agriculture, industry and the like.

The invention relates to an azo dye compound and the application thereof. The compound is the combination of at least two dyes with A in the general formula (I) selected from any structure of (a), (b)or (c); any combination with A to be at least one from (a), at least one from (b) or at least one from (c); or the combination of at least one dye shown by the general formula (1) and at least one general disperse dye, or / and a dye as shown by the formula (2). Each substituent is shown as the claim of right. The compound can dye polyester and blended fabric thereof under the condition of strong alkalinity with pH more than or equal to 11 and less than or equal to 14; the alkalinity condition can effectively remove slurry and oil on the fabric, and overcomes the defect that decomposition products can be separated out in an acid bath, and cause dyeing defect. The cloth and the fabric adopting the azo dye compound are neat and have excellent styles. In addition, the polyester fiber and the blended fabric thereof can be pretreated with alkalinity and be dyed in a bath and at one step, thus improving the efficiency, and reducing the manufacturing cost and the waste water from dyeing.
