Water soluble pigment ink-jetting printing ink

Abstract

This invention has disclosed a kind of water soluble pigment type to gush out and print blackly Colored ink, it is by the pigment, water soluble organic solvent, deionized water, Antiseptic, hand in and unite the acrylic acid resin, the surface-active agent by oneself, moist Wet pharmaceutical, dispersant, it is worth 10 that pH regulates the pharmaceutical. Group's cost inventing The water soluble pigment type textile printing ink shows the following characteristics 1) 25deg.C viscidity of hour is 6Mpa.S, 2) PH is worth 10.0, Between dyne 45 of surface tension / centimeter. Have bright in luster, And the fabric is dealt with before not needing going on, the aftertreatment is very simple Wait for the advantage, namely only need to bake proper hot 190deg.C to the fabric 5 minutes of 210deg.C cylinder press for one minute, but does not need the uapour to steam, Water-washing can get print stamp the finished product.

Description

Technical field: [0001] The invention belongs to an ink and a preparation method thereof. Background technique: [0002] Digital inkjet printing technology is a brand-new textile printing technology. Through the computer-controlled printing system, special dyes or pigments are directly sprayed on cotton, linen, silk, chemical fiber and other fabrics to print various patterns and patterns. Compared with traditional printing, the digital jet printing process has five characteristics: high production efficiency, high product quality, arbitrary batch production, energy saving, and basically no pollution. The ink used in digital inkjet printing is divided into two types: dye type and pigment type. Dye-based inks are divided into three types: disperse dyes, acid dyes, and reactive dyes. For digital inkjet printing using dye-based inks, the fabric must be treated before and after, and the printed products have the characteristics of poor water fastness, poor light fastness, and e...

AI Technical Summary

Problems solved by technology

The main disadvantages of dye-based digital printing inks are: 1. Not universal, different fibers need to use different dye inks, such as cellulose fibers need to use reactive dye inks, protein fibers need to use acid dye inks, polyester fibers need to use disperse dyes Ink, etc., and the replacement of ink needs to clean the nozzles and pipes, which is troublesome to operate

2. The stability of the ink is poor. When the storage temperature and other conditions change, it is easy to cause the crystallization of the dye, which will cause the nozzle and pipe to be blocked, and affect the printing effect.

3. The light fastness of printing color is poor

Not only the process is complicated, water and energy are wasted, but also there is a certain degree of environmental pollution
