The ink of the T-shirt printing machine is called paint ink, water-based, and its composition is as follows: coloring agent, dispersing medium (water, organic solvent), antibacterial agent, pH adjuster, moisturizer, etc., as for the pigment ink, it must be dispersed Agents and adhesives, etc. 1. Coloring agent Textile inkjet printing is divided into dyes and pigments, and there are also inks that use dyes and pigments mixed with coloring agents. It is noted that not all traditional printing dyes can be used as the coloring agent for the ink of the digital direct-injection garment printing machine. The currently developed dyes for the digital direct-injection T-shirt printing machine are mainly reactive dyes, acid dyes, and disperse dyes. . 2. Anti-bacterial agent Anti-bacterial agent can prevent the digital direct-injection garment printing machine ink from mildew during storage, and prevent the ink channel in the digital direct-injection printing machine from being blocked by ink mold. 3. PH conditioner PH conditioner is to avoid the dye hydrolysis and ensure the stability of the dye solution. On the other hand, it is to make the ink nearly neutral and avoid corrosion to the nozzle and ink system of the digital direct-injection garment printing machine. Therefore, it is usually necessary to participate in a suitable PH conditioner to control the PH value at 8 or so. 4. Surfactants Surfactants have two effects: one is to control the surface tension of the ink to make it accustomed to the request of the digital direct-injection T-shirt printing machine; the other is to help the dyestuffs improve the stability of the dye solution. Surfactants are usually glycols or naphthalenesulfonic acids. 5. The moisturizer moisturizer is used to prevent the nozzle ink from drying out too quickly and causing clogging, causing ink jet obstruction. On the other hand, it can adjust the dispersion and penetration of the ink on the fabric. 6. Dispersant Dispersant is especially used for pigment-based digital direct-injection T-shirt printing inks for the dispersion of pigments. Commonly used dispersants are polystyrene-maleic anhydride, polyacrylic acid (ester) and so on. 7. Resin Regarding pigment-based digital direct-injection garment printing machine inks, because pigments have no affinity for textile fibers, it is necessary to rely on the effect of resin binders to color textiles. Commonly used resin adhesives include polyacrylic acid, water-based polyurethane, and UV curing adhesives. The ink composition of the digital direct-injection garment printing machine can be roughly divided into the above seven components. Following the discovery and synthesis of new substances, the above seven components will be continuously updated, and more environmentally friendly and lower-consumption new substances will gradually replace the original There are materials to complete the optimized production and use.
