Regarding the ability of filter textiles, Luo Yifeng, director of the National Special Synthetic Fiber Information Center, cited the metaphor of the Japanese industry. A carbon fiber accidentally fell into the lake, leaving researchers unexpectedly to obtain an effective way to manage the water environment. It is said that in recent years, Japan has developed a special water-based environment that utilizes the special features of carbon fiber to achieve the purification of rivers, lakes, and industrial wastewater. Although the principle is not yet clear, the fact is that microorganisms in water like to attach to carbon fiber, so they can pass Repeatedly attracting and improving the water environment. In fact, this is only one of the leopards used in filter textile applications. In addition, there are steel, coal, aluminum, cement, even automotive, food more industries need a variety of filter materials, which is the industry's textile industry, there are many bright spots. This field is worth exploring Yao Mu, an academician of the Chinese Academy of Engineering, said that textiles for filtration have a long history. Today, technological advances and demand for use have led to a dramatic leap in the product range of filter textiles. For example, the paper machine speed is generally less than 500 meters/minute, high-speed paper machines can be increased to 1200 meters/minute or even higher, and the papermaking blankets are subjected to more than three times the normal tensile force, and are subject to friction, wear and fatigue. With even greater and faster press forces, the life of the papermaking felt is reduced to a few hours. Another example is the filtration and collection of various industrial fine dusts, the filtration of many industrial liquid particles, and the filtration of water in sewage treatment plants. In the words of Yao Lao, the use of filter textiles not only ensures the purity and quality of products in many industries, but also provides advanced technology and material basis for environmental protection and implementation of the "Clear Water Blue Sky" program. At the 2009 China Filter Textile Innovation Forum, everyone was full of different goals and expectations. Manager Wu of Shanghai Jierun Silk Textile Industry Co., Ltd. said that they have a bamboo carbon fiber product that has been used in clothing and household products. Occasionally, customers used bamboo carbon fiber as filter material, but they found that they can absorb sulfur dioxide, carbon monoxide and other toxic Odor, the company explored the application of bamboo carbon fiber in filter nonwovens. He pondered that although the idea is still not perfect, companies that want to contact the production and application of filtration products should seek cooperation in research and development. Shijiazhuang Changshan Textile Co., Ltd. is an advantageous enterprise of cotton textiles. It is interested in new industrial textile projects in its development strategy. Ms. Leung of the company's technology center is here to listen to the industry. She said that she has also participated in the geosynthetic materials forum held before and is now investigating in many ways, hoping to select a good project. Yantai Spandex Co., Ltd. developed Newcastle meta-aramid fiber, the current annual output has reached 4300 tons, it not only fills the gaps in the country, but also has become the world's second-largest producer. Sun Maojian, chairman of the company, said that the excellent performance of Neurama meta-aramid was gradually recognized by the industry, and the promotion of applications in many fields is very important. Low carbon economy trigger point According to data from the China Industrial Textiles Industry Association, in 2008, the amount of fiber used for filtration reached 376,900 tons (including 260,000 tons of cigarette filters). According to the normal rate of industrial development, the total processing volume will reach about 450,000 tons by 2011. The output of filtration textiles reached 410,000 tons in 2008, an increase of 12.64% year-on-year. As the country's investment in controlling environmental pollution is increasing, filter materials have a large market in China. It is estimated that the total annual income of China's environmental protection industry will reach 880 billion to 1,000 billion yuan in 2010. Sun Huaibin, director of the China Textile Economy Research Center, said that low-carbon economy has been used as a development model by western countries, and that the developed countries are also taking the low carbon economy to say things in foreign trade contacts with developing countries. He said that although this is due to the transfer of industrialization from developed countries to developed countries, developed countries have responsibilities, but we still regard environmental protection as a major issue, and textile planning clearly stipulates energy saving and emission reduction indicators. , And in the adjustment of the list of different treatment of advanced or backward process methods. “The dramatic increase in the output value of the textile industry will inevitably bring about the problem of pollutant discharge and energy consumption and water consumption. But on the other hand, there is a lot of space for textile companies to save energy and reduce emissions.†This is the view of a professor at Donghua University, who believes that Reducing the "carbon footprint" is a long-term and continuous work. An important aspect of the efforts for a low-carbon economy is to establish upstream and downstream communication. It is no wonder that the head of the business department of Shougang Environmental Protection Division stated that there is still a gap between the technology promotion and information promotion of filter material manufacturers. As a result, environmental protection units are not familiar with textile materials and have not used their length. It is no wonder that most filter textile companies believe that the “introduction and development trend of bag type dust removal in iron and steel companies†introduced by the Chief of Commerce is the most specific. Yao Laoyu warns that industrial textile companies must have a correct understanding of the industry. Filtration textiles have to be reprocessed into filtration equipment and installed in filtration systems. In addition, we should admit that we are not familiar with the use of post-processing and final products, and are not familiar with the relevant requirements and the corresponding regulations and standards. We are not familiar with the issues emerging in the new era and the problems that must be solved. Therefore, industrial textile companies must provide services for the production and processing of final roads and the use of final products, and do a good job supporting supporting angles. Zhu Minru, chairman of the China Industrial Textiles Industry Association, told reporters that in the direction of product development for filtration textiles, high-performance fibers with excellent properties should be studied and developed. For example, research and development of high-performance fibers such as polyimide fibers with excellent performance that have not yet been industrialized; improvement of product quality and stability of industrialized high-performance fibers such as polyphenylene sulfide, meta-aramid, and aryl sulfone; development of suitable In the production of high-efficiency low-resistance filter material of various materials of ultra-fine fibers; accelerate the development and industrialization of high-performance filter membrane. From the point of view of processing technology, composite nonwovens have the advantage that no single material can compare with, and thus become the inevitable trend of development of filter materials at present and in the future. It is understood that the China Industrial Textiles Industry Association is currently developing the textile industry standard “woven filter cloth†and “acupuncture nonwoven filter material†as well as the national standard “measuring method for woven filter cloth bubble point aperture†and “weaving Filter cloth permeability measurement method". Experts stated that the technical requirements and test methods for filter materials such as high-temperature smoke and dust, as well as the new product standards and the corresponding detection method standards for emerging composite nonwoven filter materials, must also be adapted to the development of the product. This is also a necessary means to speed up the transformation of results and strengthen convergence with the downstream.
Filtration textiles are good for healthy low-carbon economy
