Zhu Beina, chairman of China's < a href= "http://www.91se91.com/news/index_c.asp" > cotton textile industry < /a > Association, introduced P's domestic and foreign cotton market supply and demand situation, market characteristics and future cotton development trend this year.

However, as Gu Ping, vice chairman of the China Textile machinery and equipment industry association, said, the printing and dyeing industry is not only under the pressure of rising prices of raw materials, but also constrained by increasingly stringent environmental policies.

Gu Ping said that for printing and dyeing industry, upgrading technology, technology and equipment and key.

In the moment, printing and dyeing machinery is developing towards environmental protection, energy saving, short process, digital monitoring and intelligent. The on-line monitoring and control technology of printing and dyeing process parameters is one of the most potential technologies in the world's printing and dyeing industry. It is an effective way to improve the technical level of traditional printing and dyeing industry and solve many problems of printing and dyeing.

< p > of course, apart from the technology mentioned by Gu Ping, the participating experts also shared the contribution of dyeing and printing equipment to energy saving and emission reduction and the practical application in production.

Mr. Wang Xingnan, general manager of Shanghai Hui Yu Chemical Co., Ltd. made a speech entitled "innovative UV curing printing and finishing technology."

He introduced the innovative idea of the technology and adapted to the environment.

Through the main comparison of printing methods and the problems of various printing methods in fabric application, the paper puts forward how to get the best solution for pigment printing and how to achieve all printing requirements under the lowest energy consumption.

Based on the concept of green environmental protection advocated by the state, the environmental protection route has become an inevitable choice for the printing and dyeing industry. It is also the only way out for the sustainable development of the printing and dyeing industry. This technology is just in line with the requirements of green environmental protection. It does not require water to finish dyeing and finishing. Instead of using foam and air to replace it, it saves a lot of water energy. And based on the fast chemical reaction mechanism of free radicals, it does not need any heat to replace high energy hot air drying crosslinking process.

At the same time, at the same time, in the modern printing and dyeing plant, steam has already been used to solve the pollution caused by coal burning in every enterprise. However, there is still a coal fired heat pfer oil stove in the dyeing and printing plant, which provides the combustion source for the heat setting machine. P

With the improvement of the state requirements for environmental management, coal-fired boilers are restricted in more and more places or have been restricted, and coal-fired heat conduction oil furnace is also limited. What energy replacing coal is a common problem in many printing and dyeing enterprises. Combined with experience in various places and experience in energy-saving and emission reduction of natural gas, Mr. Fu Ji tree, the general worker of Zhejiang Yi creation printing and dyeing Co., Ltd., has published the technology of "energy saving and emission reduction technology reform" on the existing problems of the heating mode of coal fired thermal oil furnace, the advantages of the natural gas energy, the selection of natural gas energy, the technical reform process and key points, the effect of energy saving and emission reduction and the cost analysis.

< p > in fact, on the 17 day, the thirteenth China International a href= "http://www.91se91.com" > dyestuff industry < /a > organic dye and Textile Chemicals Exhibition was also held in Shanghai.

At this exhibition, environmentally-friendly additives continue to be the focus of attention.

During the "12th Five-Year" period, the textile industry will break through 50 key technologies, covering the fields of new spinning, weaving, printing and dyeing, high performance industrial textiles processing and so on. The environmental protection of textiles and < a href= "http://www.91se91.com" > textile > /a > has been attached great importance to, and the "green fabrics" which are harmless and pollution-free have become the mainstream of production and consumption.

< /p >

< p > at the scene of the conference, many technical representatives of enterprises took an environmental stance and shared their understanding of dye auxiliaries.

In the view of Xu Chengxiang, director of marketing department of WIKO chemical, with the development trend of personalized fashion, the demand for printed fabrics has increased steadily. However, its process equipment and procedures are very long. Besides the high emission, the reproducibility and stability of all parts of the fabric have always been a great challenge. The introduction of self activated slurry equipment will help to improve the stability of production.

In addition, with the maturing of all kinds of software and hardware and matching ink and technology of digital printing, matching and linking of screen printing and digital printing is also an important topic.

He explored the help of printing liquid fuels for environmental protection and so on. Besides the importance of quality, he also grasped and analyzed the reproducibility of printing quality, key elements of dyeing and printing, and discussed the key points of digital printing and the comprehensive elements of screen printing.

Since the reform and opening up to the outside world, China's printing and dyeing industry has entered a period of rapid growth. The printing and dyeing industry started from this point. When China's low-end demand for printing and dyeing was gradually saturated, with the opening of the international market, China's printing and dyeing integrated into the Global trade chain and became the world's processing vehicle. However, when the world economy was in a predicament due to the subprime crisis, China's labor force advantage was no longer, and the printing and dyeing industry also entered a critical period of pformation and upgrading. P

However, in the current complex situation, it is not feasible for Chinese printing and dyeing enterprises to rely on technology as a way to break through.

Ma P, the chief engineer of Shanxi Cai Jia printing and dyeing Co., Ltd. discussed the principle of the cotton fabric - low temperature continuous linking bleaching technology. By using the self-developed low temperature bleaching agent, the process innovation and breakthrough were achieved, which reduced the reaction temperature, shortened the reaction time, greatly reduced the amount of steam, water, electricity and chemical supplies, and reduced the pH value and COD of the sewage, so as to achieve the effect of energy saving and emission reduction.

Through popularization and application, corresponding matching process plans were studied for different equipment and process types, so as to promote popularization.

< p > Zhang Jianguo, manager of Sheng Hong group, elaborated on dyeing and finishing of 300T's spinning dyed printing fabric, which is a popular fabric in recent years. After a series of dyeing and finishing, its texture is light, soft and smooth, and its fabric is delicate. It is loved by consumers.

Taking the dyeing and finishing of 300T nylon dyeing and printing as an example, the whole process of dyeing and finishing of this kind of high molecular weight yarn was systematically introduced, including the pretreatment, dyeing, printing and finishing processes. The technical problems in the processing of the products were summarized, and a mature solution was put forward.
