Business Club Nov. 18th, 2009 News A Foreword In recent years, China's textile printing and dyeing industry has developed at a rapid rate, and its printing output has also increased. In 2001, the country’s printing and dyeing output was 17.83 billion meters, of which 4.367 billion meters was printed fabrics, accounting for 24.41% of the printing and dyeing output, an increase of 11.82%. In 2002, the national printing and dyeing output was 21.087 billion meters, an increase of 18.34%, of which the printed fabric was 4.984 billion meters, an increase of 14.18%. , accounting for 23.57% of printing and dyeing output; from January to December 2003, the printing and dyeing output reached 25.132 billion meters, an increase of 20.43% over the same period of last year. The printing output has not yet been announced. If the calculation is based on the proportion in 2002 (23%), the printing output of China in 2003 is estimated as 5.7 billion meters.
At the same time, the epidemic cycle of clothing is getting shorter and shorter, the pattern changes faster and faster, the production requirements are getting higher and higher, the order quantity is getting smaller and smaller, and the pattern piracy is rampant. Although printing companies have introduced digital methods such as printing CAD systems, laser imagesetters, flat screens, rotary screen ink jets, and wax-jet screens to improve the processing process in traditional printing methods, the printing and dyeing plants are the concept of polluting plants. Has caused a deep impression. At the same time, in the international market, the export of printing and dyeing products in our country is also increasingly hindered by the "non-trade barriers" including the environment. In terms of current technology, the digital printing market is the best way to solve many problems in the printing field.
Second, the technical characteristics of the digital printing machine Digital inkjet printing system printing process compared with the traditional printing process has fundamentally changed, the process streamlined to the design, printing, post-processing, eliminating the draft, production (or network, Engraving), screen (or rotary screen) installation simplifies equipment commissioning, slurry adjustment and other processes; the simplification of the process flow eliminates the equipment (film making machine, engraving machine, etc.) and film, screens, rollers, etc. Consumables.

Circular net, flat screen printing and digital printing contrast analysis.
The development track of the three digital printing technologies The traditional printing since the use of flat net, round net can not be separated from the net, but the cost and time consumed by the plate-making, no matter how can not meet the trend of small-lot, multi-variety modern printing, and therefore developed No version, no pressure digital printing. The basic principle is the same as the inkjet printer.
Inkjet printing technology dates back to 1884, American C. H. Richard puts water in the syringe and applies a pressure needle to fly out of the droplet. If the droplet is controlled to run in the direction, an image can be formed on the paper, called a fog ink print. At that time, because of problems with needles and ink, the effect was very poor. It was not until 1960 that it officially entered the practical stage. In the past ten years, inkjet technology was used for bar code processing or printing of product serial numbers, called printers.
Digital jet printing is a systematic project that involves cutting-edge technologies such as CAD technology, network communication technology, precision machining technology, and fine chemical technology. It is a product of the fusion of information technology and traditional technologies such as machinery, textiles, and chemicals. Since digital jet printing technology involves a lot of calculation and control, it can be said that without today's high-speed computers, there can be no digital jet printing technology. For now, the development of digital inkjet printing technology is basically synchronized with the working capability of computers. However, the development of computer technology has not shown any signs of abating. With the development of computer technology, it can be expected that digital jet printing technology in the future will also have high speed. development of. At the same time, the manufacturing technology of the nozzle also benefits from the related technologies of the integrated circuit, such as etching, precision assembly, and the like. The constant emergence of modern high-frequency, multi-nozzle nozzles proves this.
Computer technology gradually became popular in the 1990s, and continuous digital jet printing machines appeared. By 1995, mature applications had been applied to rugged textiles such as carpets and wall hangings. ZIMMER company in Austria took the lead in exhibiting digital inkjet printing prototypes for carpets, with a resolution of 9-18. Valve spray technology was used, and nozzles in the usual sense were not used; the production speed was very fast, reaching 16/min. However, due to the large droplet size and low resolution, it cannot be used in apparel fabrics.
In 1995, there was a drop-on-demand digital jet printing machine. At that time, it mainly used thermal bubble nozzles with a resolution of 300 dpi. Later it gradually developed to 600 dpi, with 4 colors as the main application.
From 1999 to 2000, digital jet printers using piezoelectric nozzles were exhibited in many countries, including the Netherlands, Japan, Switzerland, the United States, Italy, and China Honghua, with a resolution of 360 to 720 dpi, 6/h. The minimum discharge volume of the piezoelectric nozzle is very small (up to 6p1 for textile applications), the product design is finer, and the color is more uniform and natural, so it is very popular and the application area is gradually expanding.
At present, a variety of new types of digital jet printing machines have emerged, mainly using piezoelectric nozzles; the highest printing speed has been developed from 1/h in fiscal year 1990, 6/h in 2000 to 080-150/h, and the use of dyes has grown from 4 colors. To 6-8 colors and 2X6-8 colors; the application process is becoming more and more mature; the control software function is gradually perfected.
It can be seen that the development of digital jet printing technology has basically evolved from continuous shooting to on-demand jetting, from thermal bubble jets to piezoelectric jets, and from 4 colors to 6-8 colors. At present, the development of digital printing technology is showing a trend of dominating and flourishing.
From basic theory to production equipment, from application technology to dye development, and even equipment, color control methods and software are all under research and development.
In the 1990s, the number of digital printing product exhibitors at the ITMA exhibition went from 1 to 5, and the exhibitors of digital printing products at the ITMA exhibition in the past 5 years witnessed rapid development. It is reported that there are many exhibitors of digital printing at ITMA2003. Up to 23, including equipment, dyes, process technology and other aspects. In particular, the traditional printing machine manufacturers and dye manufacturers have invested great enthusiasm, such as STORK and ZIMMER have already launched four models of digital printing machines, CIBA, BASF, Dystar and other top dyes and auxiliaries manufacturers according to us Learn that many improvements have been made to their digital printing dyes. Even the Ministry of Economic Affairs of Taiwan signed a R&D alliance with many companies on December 5 last year to develop “industrial wide-format digital inkjet printing system technology.†These international companies have developed digital printing machines with such great efforts that reflect their Judgment on the development direction of textile digital printing.
Four digital printing technology applications and advanced production methods At present, digital printing technology can not only be applied to personalized, small-batch production and printing and dyeing enterprises proofing, but has entered the field of mass production. In Europe, orders within 500 meters are basically played by digital printing machines. New printing and dyeing companies that only use digital printing systems have appeared many times, combined with network design, network production and online sales, and have achieved good economic benefits. It can be said that we are ushering in a new era of digital textiles.
We have assisted companies in Hong Kong, Shenzhen, and Shanghai to establish a lot of proofing workshops that use digital printing to improve the overall economic benefits of the company. We have set up factories in Thailand, Malaysia and China to mass-produce digital printing products, all of which have become profitable. Now that we are entering a new economic era, compared with the traditional economic era in which the textile industry has flourished in the last century, the environment for textile production has undergone major changes. Looking at the current and future development prospects, the environment for maintaining mass production of textiles has changed. Printed textiles are especially the first to bear, and current production methods cannot adapt to this changing environment.
In order to survive and develop in a new environment and win in a fierce global competition, companies must change their product manufacturing strategies and seek to implement new production models to achieve goals such as shortening time to market, improving product quality, and reducing product costs. The customer can accept the time and price to meet the customer's demand for personalized customized products, and mass customization is made for this demand.
Mass customization is an emerging enterprise production and management model. Its goal is to produce customized products in large quantities, which is undoubtedly the ideal production method for manufacturing. Therefore, the concept of large-scale custom production has attracted people's attention as soon as it is proposed. It has become a research hotspot in the world in recent years. It has been successfully implemented in some enterprises and is becoming the mainstream production mode of manufacturing in the 21st century.
Mass customization production is guided by the system's thinking, with the view of overall optimization, and by fully tapping the potential of the enterprise, with the support of technologies and ideas such as standardization technology, computer technology, modern design methodology, and concurrent engineering, the ultimate realization is based on The special needs of each customer provide the process of customizing the product with high-volume production efficiency. High-volume custom production combines the advantages of high-volume production with low-cost production and customized production to meet the individualized and diversified needs of customers, enabling companies to adapt to the rapid changes in the market and provide customers with real needs at acceptable times and prices. The product. The difference between mass customization and traditional mass production is shown in Table 4.
The goal of high-volume custom production is to produce customized products with high-volume benefits. For users, the products obtained are customized and personalized. For manufacturers, the products are mainly produced in large quantities. Way formed.
The emergence and gradual maturation of digital jet printing technology has successfully solved this problem. Only a few primary colors can be used to transfer thousands of colors, enabling customers to provide sample in 24 hours, and it is convenient to organize small batches according to customer needs. , Even single-piece production, color can also be arbitrary; when the digital jet printing technology and information network technology are further integrated, you can carry out three-dimensional simulation and tailor-made for customers on the network, to achieve a completely personalized business model.
For example: Cus~mClmh. Com is one of the manufacturers that use digital printing technology in custom clothing companies. Their products include computer prints, trademarks made of fabrics, ties and scarves.
Cus~mClomh. Com applies a six-color inkjet printer. Customers can choose from 12 to 150 different patterns. They can also use the templates provided in their web pages to design their own, or pay for the company to tailor it to their own wishes. This method is highly operable and can completely avoid the inconvenience caused by large stocks.
At the same time, the epidemic cycle of clothing is getting shorter and shorter, the pattern changes faster and faster, the production requirements are getting higher and higher, the order quantity is getting smaller and smaller, and the pattern piracy is rampant. Although printing companies have introduced digital methods such as printing CAD systems, laser imagesetters, flat screens, rotary screen ink jets, and wax-jet screens to improve the processing process in traditional printing methods, the printing and dyeing plants are the concept of polluting plants.
