At the ITMA exhibition in Birmingham, England in 2003, the digital printing demonstrated to the people has shown a trend of development from proofing to scale production. For example, the DREAM digital printing machine jointly developed by Ref. Ani, Italy, and Ciba, refinement and spray head manufacturer (ScitexVision, Aprion) can produce up to 150m2/h (35kHz); hot air drying And the belt cleaning device "i. DuPontlnkJet and Artisti 2020 (or Ichi-nose 2020) jointly developed by Tojo Industries, Japan, with a processing width of 1.8 m, the cloth is conveyed by an adhesive tape, and the maximum production speed is up to 50. M2/h.
DuPontlkJet developed Fabric Fast for Artistry printing machines. This is a kind of water-based paint ink. Allegedly, after application on fabrics without pretreatment, all fastnesses after drying are also acceptable. FabricFast ink was developed in collaboration with ink researchers at Trident and Peking University researchers. Printing with Epson printheads produces a variety of colors. It can also be used for digital printing machines such as Mimaki, Roland, Mutoh and Stork. The available fabrics are cotton, polyester/cotton blended, nylon, viscose, and silk fabrics, which can be heat treated at 150°C for 2.5 minutes.
According to reports, FabricFast Ink gives textiles a simple and economical method for the rapid production of textile printing with a short process flow. This is an aqueous coating ink that does not require the use of a large amount of steam as a dye ink for fixing. FabricFast inks have the feel of dye-based inks, have a high light fastness, and can meet the various colors required by consumers.
In addition, a new coating ink is recommended by John Provost et al. and BASF company Juergen Weiser. That is, a newly developed multifunctional polymer is used as a dispersant without adding viscosity in a paint ink. This coating ink is called Helizarin EVOP-100, which has the same printing effect as the traditional paint screen printing and has good adhesion. Because He-lizarin EVOP-100 has no adhesive and low viscosity, Insignia has high color intensity, good vividness, high definition, and good friction and washing fastness.
At ITMA 2003: Helizarin EVP-100 ink debuted for the first time, only CMYK four basic colors, has now been expanded to eight Lee color (increase the golden, red, dark blue and gray), allegedly have been printed in the digital Paint ink holds a seat. Its successful application is related to the new method of fabric foresight. After pretreatment by the new method, not only the degree of cleaning, the amount of color, and the vividness are improved, but also the types of fibers such as cotton, rubber, polyester and their blends, and polyamides are expanded.
