15、ent in equipment investment of 2.8 million yuan is 25 to 500,000 yuanFlexible manufacturing, flexible production, flexible production,The flower-type conversion takes only a few minutesThe trajectory of digital printing technologyTraditional printing since no matter use flat screen, rotary screen is

16、 inseparable from the network, plate making cost and time consumed, however, no matter how to also cannot meet the modern printing trend of small batch and many varieties, thus to develop digital printing no version, no pressure. The basic principle is the same as the inkjet printer.Ink-jet printing

17、 technology can be traced back to 1884, the American people C.H.R ichard in syringe into the water, the pressure of needles flew out of the droplets, if control droplets direction, can form the image on the paper, ink printing is called fog. At the time, there was a problem with the needle and ink,

18、and the effect was very bad. It didnt enter the practical stage until 1960. The printing of inkjet technology for barcode processing or product serial number ten years ago is called a spreader.Digital jet printing is a system project involving CAD technology, network communication technology, precis

19、ion machining technologyAdvanced technologies such as fine chemical technology are the product of the fusion of information technology and traditional technologies such as machinery, textiles and chemical industry.Because digital jet printing technology involves a lot of computing and control, it is

20、 impossible to say without todays high-speed computerDigital jet printing technology. For now, the development of digital jet printing technology basically synchronous with the computers ability to work, and computer technology development are still no signs of abating, with the development of compu

21、ter technology can be expected in the futureThere will also be high-speed development of digital jet printing. The technology also benefits from the technology of integrated circuits, such as etching and precision assembly. This is demonstrated by the increasing frequency of modern, multi-nozzle jet

22、s.Gradually popularization of computer technology in the 90 s, continuous digital jet printing machine, to 1995, such as carpet, wall hanging design rugged already mature application on textiles. The Austrian company ZIMMER pioneered the digital jet printing press for the carpet, with a resolution o

23、f 9-18, using the valve spray technology and not using the usual sprinkler. Its production is fast enough to reach 16 / min. But because the spray drops are very large and the resolution is very low, it cant be applied in the fabric of clothing.In 1995 appeared the on-demand inkjet digital jet print

24、ing machine, then mainly adopts thermal bubble type nozzle, resolution 300 dpi, then gradually developed to 600 dpi, 4 color is given priority to, the basic can be applied to the fabric.Using piezoelectric nozzle in 1999-2000 of digital jet printing machine have more countries, including the Netherl

25、ands, Japan, Switzerland, the United States, Italy and China aprint company, resolution of up to 360 720 dpi, 6 / h, because of the very small amount of the minimum inkjet piezoelectric nozzle (textile applications can reach 6P1), the product design of the production is more delicate, the color is a

26、lso more uniform and natural, so popular, the application face also gradually expands.At present, various new digital jet printing machines have appeared, mainly using piezoelectric shower heads. The highest printing speed has been developed from 1 / h in 90 years and 6 / h in 2000 to 080-150 / h. U

27、se dyes from 4 to 6-8 and 2x6-8. The application process is maturing; Control software functions gradually improve.Digital jet printing technology development, therefore, is basically from the continuous shooting to the on-demand jet development, from the hot bubble type nozzle to the piezoelectric

28、nozzle shift, from 4 to 6-8 color color shift.At present, the development of digital printing technology is showing the trend of the group and the hundred flowers.From basic theory to production equipment, from application process to dye development, and even equipment, color control methods and sof

29、tware are in full research and development.In the 90 s, the digital printing products on display at ITMA exhibition vendors from 1 to 5, nearly five years of ITMA show the products on display manufacturers and rapid development of digital printing, according to the report of digital printing on ITMA

30、2003 exhibitors as many as 23, including equipment, dyes, process technology and other aspects. In particular, traditional printer manufacturers and dye producers have invested a lot of enthusiasm.Such as STORK and ZIMMER has been respectively introduced four models of the digital printing machine,

31、CIBA, BASF, Dystars top dyes and additives production enterprises as far as we know have been introduced to them repeated improvement of digital printing dye. Even last December 5, the ministry of economic affairs with many enterprises r&d alliance, the development of digital inkjet printing system

32、technology industrial wide type the international enterprise development and digital printing machine with so much strength reflects their direction of development of textile digital printing.The application of digital printing technology and advanced mode of productionAt present, digital printing t

33、echnology can not only apply to individuation, small batch production and printing and dyeing enterprises, but also has entered into the mass production area. In Europe, within 500 meters of order basically taken by digital printing machine, only use the digital printing system a new type of printin

34、g and dyeing enterprises have appeared many, and network design, production, sales networks, and achieved good economic benefits. Arguably, we are embracing a new era of digital textiles.We have helped companies in Hong Kong, shenzhen and Shanghai to establish a number of sample workshops with digit

35、al printing and improve the overall economic benefits of enterprises. We have set up several factories in Thailand, Malaysia and at home to produce digital printing products, all of which are profitable. Now we are entering a new economic era and the textile industry booming in the last century, com

36、pared to traditional economy era textile production environment, great changes have taken place in as shown in table 3The new economic age of the traditional economyCustomers can be selective and globalConsumer demand is cheap and reasonable, and the basic needs are personalized and diversifiedThe m

37、arket is relatively stable and fast and volatile and unpredictableLow cost, high quality customer, fast deliveryThe market method is standardized, serialized, large quantities single, small batch, many varietiesThe global distribution of technical resources is relatively centralizedCompetitive facto

38、r performance is more than flexible production and response speedAs you can see from table 3, the environment for maintaining mass production of textiles has changed in the present and future.Printed textiles are especially the first to be used in the current mode of production to adapt to this chan

39、ging environment.In order to survival and development in the new environment, to win in the fierce global competition, enterprises must change the product manufacturing strategy, seeking to implement the new production mode to shorten time-to-market, improve quality, reduce product cost and other ob
