[0042] Table 2 is the ink ratio of the other three colors of cyan, yellow and black (CYK) in the CMYK four-color inkjet.

[0043] Component

[0044] The preparation method is the same as in Example 1, and the cyan, yellow and black inks made according to the above proportioning ratio are processed on the PressVu UV UV curing digital printer produced by U.S. Witt (VUTEK) together with the magenta ink made in Example 1. Cotton, polyester-cotton and silk fabrics are printed with smooth inkjet, bright colors, very good printing performance, clear and vivid patterns on fabrics, good hand feeling and excellent water resistance.

Abstract

UV solidified printing ink for digital code printing and dyeing is composed of polyurethane acrylate, prepolymer, activity monomer, dyestuff, light initiator, dispersant agent and other addition agents. The prepolymer has the character of low viscosity and good flexibility. The ink doesn't contain organic solvent and has wide material adaptation, storage stability and softness.

Description

technical field [0001] The invention relates to an ultraviolet light curing ink and a preparation method thereof, in particular to an ultraviolet light curing ink for digital printing and dyeing and a preparation method thereof. Background technique [0002] Digital printing and dyeing technology is a brand-new textile printing technology. It uses a computer-controlled printing system to directly spray special ink on cotton, linen, silk, chemical fiber and other fabrics to print various patterns and patterns. Compared with the traditional production process, the digital printing and dyeing process has five major advantages: first, high production efficiency, second, good product quality, third, arbitrary batch production, fourth, energy saving, and fifth, basically no environmental pollution. Digital printing and dyeing technology has been more and more widely used in the world in recent years. This is the product of the combination of computer technology and printing and dy...
