During the seminar, the representatives also visited the zhejiang yongxin printing and dyeing co., ltd. located in jiaxing city, zhejiang province with great interest, and highly evaluated the successful experience of yongxin in equipment and process innovation and enterprise management.

　　"Innovation, energy saving, environmental protection, efficiency" became the key words of the seminar

　　"According to the economic growth plan put forward by the state during the 12th five-year plan period, the pace of economic growth in China seems to be slowing down, but in fact, it is a process from fast to good, with more emphasis on the benefits and quality of economic growth, and more emphasis on the harmonious development between human and nature. Under such a macro background, the textile printing and dyeing industry needs to transform the mode of economic growth through scientific and technological innovation, and improve the unit output value, added value and profit margin of products with the help of advanced finishing technology of printing and dyeing. Gong jinli stressed in his opening speech that in the next five years, the textile, printing and dyeing industry will face the arduous task of energy conservation and emission reduction in terms of energy consumption, water consumption and COD content. Gong jinli pointed out that how to build a resource-saving and environment-friendly industrial structure and achieve sustainable development of the industry requires in-depth exploration and cooperation among enterprises in various fields such as dye production, equipment manufacturing and post-processing.

　　At present, our country has not enough resources to support behind the dyeing and finishing technology, also do not have enough environmental capacity to carry high pollution mode of production, the maximum control the consumption of non-renewable resources, reduce waste emissions in production process, will become the main target of the printing and dyeing enterprises production and technology development in the future and the breakthrough direction. Wang jiyong put forward Suggestions from three aspects when he made the theme report of "preliminary exploration on sustainable development of printing and dyeing industry". First, local governments and enterprises can try to plan and build printing and dyeing industrial parks, explore the development mode of low-carbon recycling economic parks, and realize centralized heating and pollutant treatment in the parks. This move for a small scale, a single product printing and dyeing enterprises, can greatly reduce operating costs and environmental pressure. Secondly, a batch of advanced equipment with high degree of automation, low energy consumption and low pollution should be implemented as soon as possible, and the outdated production technology and equipment with long process, high energy consumption and water consumption and large bath ratio should be eliminated. With the help of digital on-line detection and control technology, automatic distribution system of dyeing materials, waste heat recovery and utilization device and other advanced production systems, printing and dyeing production is transformed from extensive to refined. Third, further promote the application of advanced technologies such as biological enzymes in the modern printing and dyeing industry to promote the "green dyeing and finishing" revolution.

　　Professor liu zengjie, a member of hebei provincial printing and dyeing committee, said: "the interaction among printing and dyeing enterprises, dyeing additive manufacturers and equipment manufacturers is one of the highlights of the seminar. The three parties play a vital role in enabling more technicians from the front-line of production to pay attention to, understand and think about the development problems of the printing and dyeing industry, promote independent innovation of dyeing and finishing technology, equipment and industrial structure optimization.

　　New technologies, new materials and new technologies lead the way for future development

　　Under the guidance of relevant national and industrial policies and in the face of opportunities and challenges under the new situation, relevant units of the textile, printing and dyeing industry in China have the courage to innovate and keep forging ahead, and have made a series of important achievements and progress in the development and application of new technologies, new equipment, new processes, new auxiliaries and new materials in finishing after printing and dyeing.

　　At the meeting, technical representatives from the front-line production of enterprises communicated their research results through thematic reports, keynote speeches and interactive discussions. Xu changyuan, engineer of hangzhou kaiyuan computer technology co., LTD., explained in detail the application of online acquisition system in dyeing and finishing informatization. Xu changyuan said that hangzhou kaiyuan has long been committed to the automation of textile printing and dyeing, information technology and product research and development, its domestic pioneering printing and dyeing enterprises production process, equipment operation and energy consumption indicators real-time data collection and control system in the domestic major enterprises application effect is good.

　　Dyeing and finishing industry is a large energy consumption, waste gas purification, heat recovery is one of the key energy-saving emission reduction, but also dyeing and finishing enterprises to reduce production costs, improve the production environment needs. Naturally, this topic has become a hot topic in all previous seminars on finishing after printing and dyeing. At this symposium, Chen liqiu, a senior engineer from the dyeing and finishing committee of the Chinese textile engineering society, put forward the solution of combined heat pipe waste heat recovery heat exchanger. According to Chen liqiu, the waste gas purification and heat recovery device of the shaping machine adopts superconductivity heat exchanger, which can effectively improve the production capacity of dyeing and finishing enterprises, reduce energy consumption, and significantly reduce the emission of SO2 and CO2. After being used in dyeing and finishing plants in guangdong and other places, good economic and social benefits have been achieved.

　　In research and development and application of new finishing technology, jiangnan university shu-gen wang, a professor from the college of textile and garment "ring of reactive paste in the application of functional textiles deodorization finishing" project, deputy director of the jiangsu province textile engineering society Gu Hao of "the new development of multi-functional composite finishing of textiles" project, as well as the equipment of peoples' institute of Dr XiaoGong "antibacterial deodorizes and deodorant processing related fundamental problem" and other research projects have caused a lot of attention from the representatives.

　　"It is necessary for the development of the printing and dyeing industry to strengthen the research and development and innovation of printing and dyeing of new fiber fabrics and to develop post-finishing technology with advanced technical content." Wang jiyong says, "dye whole, the key is whole." At present, the whole industry is facing a more serious situation, the energy cost and the price of production materials continue to rise, which brings increasing pressure on enterprises. In this case, the value brought by post-finishing is more prominent, because such as non-hot, anti-bacterial, flame retardant, anti-static and other advanced post-finishing technology can greatly improve the product quality level and added value, and become the key factor for enterprises to decide the victory or defeat in the market competition.

　　It is reported that the national printing and dyeing finishing academic seminar sponsored by the China textile engineering society, China textile engineering society dyeing and finishing professional committee to undertake, has been successfully held seven sessions. Has become an important platform for academic exchanges in the industry, with a wide range of influence. This seminar has received a positive response from the textile engineering dyeing and finishing professional committees of various provinces and cities in China. After expert selection, nearly 70 papers were selected into the proceedings of the eighth national symposium on finishing after printing and dyeing, which has a strong academic and practical value.
