Digital printing is free of plate making and pollution, especially in the sense of pattern level and convenience, and is gradually accepted by the market.
 
 
 
Du Yuzhou, President of China Textile Industry Association, said at the National Textile Science and technology conference that during the 12th Five Year Plan period, the textile industry will break through 50 key technologies, covering new spinning, weaving, printing and dyeing, high-performance industrial textile processing and other fields. Digital printing technology will play an increasingly important role in this technological wave.
 
 
 
The industrial era of digital printing is coming. "Digital printing equipment is revolutionary to the textile industry," said Dr. Xu Songyi of Zhejiang Institute of industrial economics When visiting printing enterprises in Zhejiang Province, the reporter learned that many enterprises pay close attention to the industrialization application trend of digital printing technology and hope to know the industrialization trend of digital printing. Traditional printing enterprises are looking for a way out in the face of upgrading and transformation, and the industrialization of digital printing will bring a spring breeze to enterprises.

From proofing to industrialization
 
 
 
Digital ink jet printing ready
 
 
 
At present, the digital ink-jet printing market is becoming more and more popular, and even many Taobao sellers regard "digital printing" as the key word of clothing products.
 
 
 
Li Li, deputy general manager of Hangzhou Honghua Digital Technology Co., Ltd., said: "nowadays, the fashion cycle is shortened and the pattern changes a lot. More and more consumers are pursuing unique fabric pattern. In order to meet the market demand, the fabric manufacturers have developed a large number of patterns to provide choices for clothing brands, so that the printing plant can receive orders, reduce batches and increase varieties. "
 
 
 
The traditional printing process consumes the cost and time of plate making. Small batch orders increase the cost of fabrics using the traditional printing process and increase the difficulty of receiving orders. Digital ink-jet printing is not only accurate in color, but also natural and smooth in color transition. Although it is more expensive than ordinary flat screen printing, it is worth the money for fashion conscious consumers.
 
 
 
The popularity of digital printing is closely related to the popularity of fashion, so is the market of digital ink-jet printing.
 
 
 
Printing of wool fabrics is facing a good opportunity
 
 
 
Chen Rongqi, member of Expert Committee of China printing and dyeing industry
 
 
 
With the rapid development of domestic economy, people's living standards have improved significantly. Consumers who pay attention to the quality of life begin to pay attention to wool textiles, which brings a good opportunity for digital printing of wool fabrics. Digital printing is suitable for high-grade wool fabrics, which have the characteristics of small batch, exquisite pattern and strong fashion sense.
 
 
 
It should be noted that the fabric preparation for digital printing of wool fabric is generally subject to chlorination treatment, which can significantly improve the color depth, brightness and clarity of the spray printing pattern. In addition, paste, hygroscopic agent, acid releasing agent and other factors have obvious influence on the spray printing effect. The digital printing of wool fabric should also be considered in combination with the whole dyeing and finishing process to achieve good printing effect without affecting the high-grade style of wool fabric.
 
 
 
The ink used for digital jet printing of wool fabric is mainly acid ink or active ink produced by some foreign large companies. The color depth, color light and color fastness of the ink are very important. In addition, the adaptability of the nozzle is the most important, otherwise the ink blocking the nozzle will be a very annoying thing.
 
 
 
The digital printing of wool fabric is now rising quietly in the industry, which is also an important direction of the development of digital printing technology after silk.

Print personalized textile products

The traditional printing process is long, which not only has complex process and long cycle, but also directly affects the quality of printing. Today, the demand of textile market is becoming more and more diversified and individualized. Facing the requirements of small batch, multi variety and short cycle of customers, if digital printing technology is adopted, a series of processes and equipment such as traditional process description, production, screen making and carving can be omitted. Only a few primary colors can be used to allocate tens of millions of colors, and samples can be provided to customers in time Organize small batch or even single production.
 
 
 
In the traditional printing mode, printing enterprises have introduced digital means such as printing CAD system, laser Phototypesetter, flat screen ink-jet, circular screen ink-jet, wax spray screen machine to improve the processing process, but the cost and time consumed by traditional printing plate making, no matter how, is difficult to meet the requirements of modern printing trend of small batch and multiple varieties. Digital printing has its own advantages in this respect.
 
 
 
Zhejiang Modern Textile Industry Research Institute digital technology center is engaged in the production, application, research, promotion and related services of digital printing business entity, with imported high-speed digital inkjet printing machine.
 
 
 
We are optimistic about the development of digital printing industry in the future. The faster, the better
 
 
 
Yang Puxian, senior engineer of Jiangsu textile industry design and Research Institute
 
 
 
As the digital printing is line by line inkjet printing, the speed is not as fast as that of round screen and flat screen printing. If the speed of the equipment is increased, the precision of the printing products will be reduced, which will affect the quality of the products. Especially for some coarse and thick fabric, it needs the penetration of ink, which affects the printing effect quickly, and the printing speed of more complex pattern will be slower. If the production speed of equipment is slow, the productivity will be relatively low, and the production time will be relatively long, so the depreciation cost of machinery and equipment will be greatly increased, which is the cost that must be paid.
 
 
 
The quality and price of ink is also a key factor in the industrialization of digital printing. The coordination between ink and digital printing color matching software is a key factor. What kind of ink is used for what brand of machine and the matching software are related to compatibility, while the price of ink is directly related to the cost of digital printing.
 
 
 
At present, the research of digital ink-jet printing technology mainly focuses on the following aspects: first, the development of ink-jet printing machine; second, the development of intelligent CAD system and its related software; third, the development of ink. For the first and second aspects, there are extensive researches abroad and they are becoming more and more mature. For the third point, domestic enterprises are still working together with developed countries to study ink formulations suitable for all kinds of fibers and fabrics. The ink for digital ink-jet printing in foreign countries is expensive, and it needs to be debugged when used with domestic digital printing machine.
 
 
 
Promote the development of wool fabrics
 
 
 
Chen Weiguo, Professor of Zhejiang University of science and technology
 
 
 
As a high-grade clothing fabric, printed wool fabric is mainly produced in response to the needs of fashion clothing. There are many changes in pattern to reflect the personalized requirements of small batch production of fashion.
 
 
 
At present, the most advanced screen printing machine is suitable for the high-speed operation of high-yield production. For the small batch of wool fabric printing processing, it needs to go through the process of pattern design, draft tracing, screen making, etc., not only processing time is long, but also the cost is not low. At the same time, the general printing enterprises do not have the conditions for the post-processing of wool fabrics, which limits the production of printed wool fabrics. In addition, in the screen printing process, to achieve the accuracy of multi-color pattern, it may cause waste of fabric. In the complex printing technology, such as discharge printing, this phenomenon is more serious. Digital printing solves these problems in traditional wool printing, and promotes the quality and quantity of printed wool fabric.
 
 
 
Break through the limitation of pattern coloring
 
 
 
Xu Changyuan, marketing department of Hangzhou Kaiyuan Computer Technology Co., Ltd
 
 
 
The production process of digital printing gets rid of the process of color separation, plate making and screen making in the production process of traditional printing, thus greatly reducing the production time. The way of accepting patterns can be achieved by various advanced means such as CD-ROM, e-mail, etc. generally, the proofing time does not exceed one working day, some of them only need a few hours, while the traditional proofing time is generally about one week. The shortening of proofing cycle and the reduction of proofing cost bring more market opportunities to enterprises. Choose any pattern, without considering pattern type and chromatic number, printing color can reproduce almost any color in nature. Digital printing technology for designers, can fully realize their own design ideas.
 
 
 
Digital printing technology can adopt digital pattern. Through computer color measurement, color matching and printing, the color of digital printing products can reach 16.7 million kinds in theory, breaking through the limitation of color matching of traditional textile printing and dyeing patterns, especially in the printing of high-precision patterns such as color gradient and cloud pattern, digital printing has more advantages in technology. The added value of fabric and clothing produced by digital printing technology is relatively high.


Several problems should be paid attention to
 
 
 
Zhang Jun, general manager of Jinshu silk printing and dyeing Co., Ltd
 
 
 
Digital ink-jet printing technology has been paid more and more attention and has a broad development prospect, but several problems should be paid attention to. First of all, the production status of enterprises is generally sensitive, and the printing speed is slow. In general, the traditional printing factory prints at the speed of several meters to tens of meters per minute, but the digital ink-jet printing takes several minutes to print one meter, so the printing speed is relatively low. Secondly, the digital printing machine is more "delicate", the daily maintenance cost is high, the nozzle life is the key, replacing a nozzle is very common. Thirdly, the digital ink-jet printing fabric needs to be processed before printing, so that the fabric can meet the requirements of ink-jet printing, which requires skilled printing technicians. In a word, the development of digital ink-jet printing is still restricted by the production cost, which will be gradually reduced with the popularity of digital printing, but the cost of digital printing will be several times that of traditional printing, which is determined by the characteristics of digital printing.
