Dyeing and printing industry is the most important step in creating added value and enriching design and color in textile industry. It is the technology intensive industry with complicated technology, many parameters and production, management control elements. So every innovation of dyeing and printing industry involves many aspects, such as technology, equipment, chemical innovation.

Since the 12th Five-Year Program, dyeing and printing industry in our country has made great progress, which cant depart from the support of dyeing and printing equipment, for example, low liquor ratio dyeing machine, continuous pretreatment equipment, digital printing equipment, energy conservation emission reduction equipment, the fourth generation machine of modular tail gas treatment, etc. Moreover, magnetically levitated electric machine is also included. All of them have made great improvements during the 12th Five-Year Program.

At present, the overall level of dyeing and printing equipment is not low, and the cost performance is high. But there are gaps in a few aspects, such as the accuracy and durability of the equipment is a bit poor, the consumable parts are not good enough, so there is gap between control level of automation and equipments of dyeing and printing abroad. As the downstream consumer, the dyeing and printing enterprise rely more on the textile enterprises, a tiny part of the enterprises will research on their own in the aspects, therefore, the dyeing and printing enterprises hope that they could promote and make perfect equipments, controlling the cost effectively, and keeping price advantage, leading to high quality and inexpensive price.

Intellectualized dyeing and printing is of great significance

China puts forward “made in China 2025” in 2015, the important part of the planning is“smart manufacturing”, the integration between Internet and traditional industries will make the manufacturing go to the commanding heights in a new round of development, “smart manufacturing” will be the main direction in the future.

As a technology-intensive industry, theres a particular meaning for dyeing and printing industry to realize intelligence. The intelligence will impact the industry in five aspects in the short term. One is to reduce labor costs and improve production efficiency; secondly, to raise the level of technology and management; thirdly, to improve the energy conservation and emission reduc- tion as well as clean production level; fourthly, to improve the quality and stability of the product; fifthly, to increase the speed of market reaction and strain capacity. With the constant improvement of the intelligent level and the integration of the Internet, the smart manufacturing will play a more and more important role in the industrys transformation and upgrading.

The constant improvement of intelligent dyeing and printing industry will provide a better foundation for the integration of traditional manufacturing industry and the Internet, the combination of Internet and traditional manufacturing will inspire new vitality and development space. Through intelligent manufacturing, some digital and intelligent development will make cloud production, cloud market and cloud design impossible. In addition, the intelligent degree of industry will also unceasingly to enhance. The single intelligent equipment will transfer to the whole factory intelligent, and the business intelligence will convert to the whole industry with a higher level and wider range. Recently, the dyeing and printing industry focus on developing intelligent production and management. Otherwise, intelligent design and service will enter into a wider development space fused with the Internet in the future.

Digital printing remains development

In recent years, with technological progress and equipment upgrade, the digital printing develops fast and remains wider development space in the future. From angles of technical skill, the digital printing remains bottleneck to break through in the short term. Compared with the traditional printing, each of them has its own advantage. So the digital printing develops gradually and couldnt replace the traditional printing with a sudden.

The development speed of digital printing depends on the development of technology and equipment. At present, the digital printing has made a lot of technical breakthroughs and carried on the corresponding promotion in the market, so the market prospect is wide. They have take advantages in terms of precision, high speed, and digital. In aspect of equipment, the development of digital printing also needs the innovative equipments which are more cost-effective and conducive to the industrial production. Theres also drop space for ink costs and sets of chemicals, its beneficial for development of digital printing in this field of researching.

Represented by digital ink-jet printing and eight-color printing, the speed of printing increased greatly through years of accumulation. The cost of ink reduced and the obvious technological progress. Various factors have made the digital ink jet printing enter into a period of rapid development. For example, the eight-color printing achieved fine printing of eight separate colors through traditional transformation of flat screen, rotary screen and roller printing. Zhejiang R.G.B Textile Printing and Dyeing Co., Ltd., Zhejiang Saintyear Textile Co., Ltd., Yuyue Home Textile Co., Ltd., and Jiangsu Chenghong Co., Ltd. are the leading enterprises in this area. In the aspect of digital printing, Hangzhou honghua Co., Ltd., Heimai Digital Technology Co., Ltd., Hangzhou Kaiyuan Computer Tech. Co., Ltd., Italy MS are very active with constant innovative productions.

Equipment innovation needs the unit between ups and downs

At present, the imported equipment used by domestic dyeing and printing enterprises occupies certain proportion; there is cooperative R&D between dyeing and printing enterprises and textile machinery enterprises, for example, Qingdao Phoenix Dyeing and Printing Co., Ltd. That is very special, they give priority to domestic equipment and join hands with the textile machinery to research and develop. In addition, there are also excellent enterprises, for example, CHTC Fongs Industries Co., Ltd. that does so well and is popular with the dyeing and printing enterprises.

Dyeing and printing is a relatively complex process, different product possess different craft and requirement as well as different equipment to achieve. such as the natural fiber and polyester fiber dyeing, different properties and craft lead to different equipments, In addition, the process of dyeing and printing is long, pretreatment, dyeing printing and finishing process involve many aspects; there are many testing steps, the dyeing and printing process take the proportion of 60% - 70%. The numbers of machines for testing is large, involving many varieties; Dyeing points a lot of kinds, different flow machine, air machine, jigger, seven or eight kinds of dyes and different kind of technology leads to different equipment; For the different dyeing process of fiber, yarn, and grey cloth, there are lots of equipment categories, moreover, the market space is large, and occurred more innovative ideas. So the innovation of printing and dyeing equipment is a systematic project, needing the textile enterprises constant innovation to support.
