Because digital inkjet printing technology involves a lot of calculation and control, it can be said that digital inkjet printing technology is impossible without today's high-speed computer. At present, the development of digital inkjet printing technology is basically synchronized with the working ability of computers, but the development of computer technology still shows no signs of weakening. With the development of computer technology, it can be predicted that the future digital inkjet printing technology will also develop at a high speed. At the same time, the manufacturing technology of nozzle also benefits from the related technologies of integrated circuits, such as etching and precision assembly. The continuous appearance of modern high-frequency multi-nozzle nozzles proves this point.
With the gradual popularization of computer technology in the 1990s, continuous digital jet printing machine appeared, and by 1995, it has been applied to coarse textiles such as carpets and wall hangings. An Austrian company took the lead in exhibiting the digital jet printing prototype of carpet, with the resolution of 9- 18, using valve jet technology without using the usual nozzle; Its production speed is very fast, which can be 16/ min. However, due to the large droplets and low resolution, it can not be used for clothing fabrics.
1995 The digital inkjet printer appeared on demand. At that time, hot bubble nozzles were mainly used with a resolution of 300dpi. Later, it gradually developed to 600dpi, mainly in four colors, which can basically be applied to fabrics.
During 65438-0999-2000, digital jet printing machines with piezoelectric nozzles were exhibited in Holland, Japan, Switzerland, USA, Italy, China and other countries, with the resolution of 360~720dpi, 6/h. Because the minimum ink-jet volume of piezoelectric nozzles is very small, the products produced are finer in pattern, more uniform and natural in color, which is popular and the application fields are gradually expanding.
A variety of new digital inkjet printers have emerged, mainly using piezoelectric nozzles; The highest printing speed increased from1h in 990 and 6/h in 2000 to 0.80-1.50/h; The use of dyes developed from 4 colors to 6-8 colors and 2X6-8 colors; The application technology is becoming more and more mature; The function of the control software is gradually improving. It can be seen that the development of digital inkjet printing technology is basically from continuous shooting to on-demand spraying, from hot bubble nozzle to piezoelectric nozzle, from 4 colors to 6-8 colors.
Undoubtedly, the emergence and successful application of digital printing technology is undoubtedly a major technological revolution in the textile industry, which is of milestone significance. The economic and social benefits brought by digital printing will have a far-reaching impact on the world, especially on China, a textile printing and dyeing country. Like the previous industrial upgrading and transformation, the emergence of new digital jet printing technology is both a challenge and an opportunity. China textile enterprises must seize the opportunity in the upcoming transformation.
