Digital-printing active ink suitable for wide-width micro-piezoelectric printer

Abstract

The invention relates to a digital-printing active ink suitable for a wide-width micro-piezoelectric printer. The digital-printing active ink is characterized in that an ink formula system contains the following ingredients by weight percent: 5-15wt%of active dye, 5-40% of humectant, 1-10wt% of viscosity regulator, 0.1-1wt% of bactericide, 0-1wt% of pH buffering agent, 0-5% of surfactant, 0-2% of dispersing agent, 0-10% of cosolvent and the balance of deionized water. The digital-printing active ink disclosed by the invention has the characteristics that the performance parameter can favorably adapt to the wide-width micro-piezoelectric printer, and has good printing stability on the type of printer; the digital-printing active ink has good reaction activity and excellent fixation performance on fabric such as cotton, hemp, hair and silk, and has good washing fastness, good perspiration fastness, good friction fastness and good light fastness on the fabric; the digital-printing active ink is wide in color range and excellent in color expressive force; and through a strict high / low temperature ageing experiment, the digital-printing active ink is good in storage stability.

Description

technical field [0001] The invention relates to a water-based reactive dye ink, in particular to a reactive dye ink suitable for wide-width micro piezoelectric printers. Background technique [0002] In recent years, textile printing technology has increasingly developed towards digital technology. There are several reasons for this: First, the requirements for environmental protection. The waste of dyes and chemicals in traditional flat screen and rotary screen printing is the most serious. Discharge into the environment will Cause serious environmental pollution, digital printing technology is based on the design pattern, through the RIP (Raster image processor) software on-demand injection, so there is basically no waste of dyes and chemicals, and save energy to a large extent. The second is that if some small batches and multi-variety orders use the traditional printing method, screen making, color matching, long production cycle, and uneconomical, such small batches and...

The second is that if some small batches and multi-variety orders use the traditional printing method, screen making, color matching, long production cycle, and uneconomical, such small batches and multi-variety orders can be digitally printed without any minimum minimum The order quantity meets the needs of customers in a timely manner

In terms of the stability of the ink, the current technology still has some defects, and the adaptability to different models is somewhat narrow
