Abstract

The invention discloses a colorant for digital printing of polyester fabric, comprising, by weight, 60-80% of disperse red, 8-15% of disperse pink, 5-15% of a dispersing agent, 2-5% of a dye leveler,2-5% of an anti-wrinkle softener, and 1-5% of an irrigation inhibitor. The invention also discloses a production technique of the colorant, characterized by comprising the steps of (1) adding cold water into a vat; (2) adding the dye leveler and the irrigation inhibitor into the vat; (3) adjusting PH via glacial acetic acid; (4) after first heating, adding the disperse red No. 60, the disperse pink BG and the dispersing agent, and maintaining; (5) continuing to perform heating, maintaining the temperature, and performing color matching. The colorant has the advantages of good chromatic stability and bright color, high color yield, clear outline of printed patterns, good water fastness and friction fastness, and good environmental friendliness and safety.

Description

technical field [0001] The invention belongs to the field of dyeing and printing of polyester fabrics, in particular to a coloring agent for digital printing of polyester fabrics and a production process thereof. Background technique [0002] At present, digital printing has been widely promoted and applied in the market, but in the printing process, there are disadvantages such as unstable shade, low dyeing rate, unclear printing outline, not bright color, and poor rubbing fastness. [0003] Disperse Red 60#, also known as 1-amino-2-phenoxy-4-hydroxyanthraquinone, is the main dye for dyeing polyester, with bright shade and excellent light fastness. It is often combined with disperse yellow RGFL and disperse blue 2BLN to form the three primary colors, and it is suitable for high temperature and high pressure dyeing. It can be used for direct printing of polyester and nylon fabrics, and also for digital printing. However, the application of disperse red 660# in digital prin...
