Digital inkjet printing is a new type of printing technology. Compared with traditional printing technology, the digital inkjet printing production process does not require the traditional color printing, coloring, film making and web making processes in the production process, and the process route is shortened. Thereby, the production time is greatly shortened, and the consumption of the net-making labor, the network making site and the printing net is reduced, and the proofing cost is greatly reduced due to the simplification of the process. Digital inkjet printing can accept patterns by means of CD-ROM, mail, etc. Generally, the proofing time is no more than one working day, and the traditional proofing cycle is generally about one week. The shortening of the proofing cycle and the reduction of costs have brought more market opportunities and profit margins to the company.
Promoting structural adjustment and technology upgrades Digital inkjet printing technology breaks the limits of traditional printing's color registration and flower back length. Because digital inkjet printing technology can use digital patterns, color measurement, color matching, and printing through computer, breaking through the color limitation of traditional textile printing patterns, especially in the printing of high-precision patterns such as color gradient and moiré. Digital inkjet printing has more technical advantages. In addition, the traditional printed patterns are often limited by the length of the "flower back", and the digital inkjet printing does not have the concept of "flower back", thus greatly expanding the space of textile pattern design.
Since the digital inkjet printing production process all realizes computerized digital production, the production flexibility is greatly improved, and the production batch is not subject to any restrictions. Some products can even be delivered on the same day, and it is desirable. In addition, due to the application of computer technology, printing a series of patterns of different shades of the same pattern, as well as the designer's modification of the pattern and color at any time during the production process, are the technical advantages of digital inkjet printing.
Digital inkjet printing has brought a technological revolution to the traditional textile printing and dyeing industry, which is in line with the development trend of the textile market from mass production mode to individualized and rapid response transformation. It is important for promoting the structural adjustment and technological upgrading of the textile printing and dyeing industry. significance.
Promoting the goal of energy saving and emission reduction Because printing and dyeing processing is a hot processing and wet processing process, it needs to consume a large amount of energy and water resources and produce printing and dyeing wastewater in the processing process. The printing and dyeing industry is the focus of energy saving and emission reduction in China's textile industry. In recent years, the printing and dyeing industry has done a lot of work in energy conservation and emission reduction, and has achieved remarkable results. However, with the continuous rapid development of the industry, the total amount of water consumption and total pollutant emissions continue to increase. Printing and dyeing wastewater discharged from the printing and dyeing industry has become one of the key pollution sources in China's industrial system. At the same time, the high cost brought about by water consumption and pollution control has seriously weakened the competitiveness of enterprises and has become a bottleneck restricting the healthy and sustainable development of the textile printing and dyeing industry.
The "Twelfth Five-Year Development Plan for the Textile Industry" proposes that the energy consumption per unit of industrial added value is reduced by 20% compared with 2010, the industrial carbon dioxide emission intensity is reduced by 20% compared with 2010, and the water consumption per unit of industrial added value is reduced by 30% compared with 2010. The main pollutant emissions are 10% lower than the 2010 development target. The textile printing and dyeing industry has a long way to go.
The use of dyes in the digital inkjet printing process is “on-demand†by the computer, which can greatly reduce the consumption of dyes in the production process and the resulting printing and dyeing wastewater. Compared with traditional flat and rotary screen printing, digital inkjet printing has the following advantages in energy saving and emission reduction: (1) Digital inkjet printing produces less waste water than flat and rotary screen printing. The process of digital inkjet printing and round screen printing is printing-drying-steaming-washing. The washing process is to remove the paste on the printing cloth. Because the amount of paste used in digital inkjet printing is very low, The amount of water used for washing is much lower than that of flat and rotary screen printing. (2) Digital inkjet printing technology is directly controlled by a single computer, which is lower than the electricity and water consumption required by the traditional printing and dyeing production line. (3) Digital inkjet printing controls the form of printing nozzle operation by computer input digital form, and realizes on-demand printing, so that the COD production per unit output is lower than that of flat and rotary screen printing. (4) The color value of digital inkjet printing washing wastewater is only tens of times, and the color of flat and rotary screen printing washing wastewater is as high as 500-600. In general, compared with the traditional printing process, the amount of digital inkjet printing dyes is saved by 20% to 40%, and the water consumption is saved by 40% to 60%.
Promote the printing and dyeing industry from the big change to the United States, Japan and Western Europe in the textile printing and dyeing industry value chain, export high-tech content, high value-added products, control the market channels and technology, occupy the two ends of the industrial chain. China's printed fabrics and exports are large, but there is still a considerable part of printed fabrics that need to be imported. Among the export profits of printing and dyeing products, China's fabric manufacturers only get 10% of them. In the traditional textile printing and dyeing industry, under the business model of sample processing, the living space of printing and dyeing enterprises is getting smaller and smaller.
Digital inkjet printing technology provides technical support for the production of high-quality, high value-added printing products, and will become an important means to promote the upgrading of printing industry, enhance the international competitiveness and added value of printing products, and improve the profitability of enterprises, and accelerate the printing of traditional textiles in China. The process of “changing from big to strong†in the industry.
