In the past, people's ideas, filtration is a profound, but also mysterious concept, with the filtration market has steadily increased year by year, and the high profits, causing more and more people pay attention and funding, especially non-woven production technology development is very fast, the application field is gradually replaced by paper, machine weaving, glass and other materials, no doubt the market requires a higher technology content of new non-woven fabrics, manufacturers of return on investment is also higher.

However, blindly into the market filtration is not practical, need to innovative thinking, cutting-edge technology, at the same time, but also output with low cost and high efficiency products. These characteristics make filtration industry survived a severe economic crisis. At the beginning of the new year, whether novice or veteran producer are in full swing in the development of new technology, develop new uses, in order to meet the high standards of the downstream customers requirements.

By the non-woven industry association (Inda) released an official report shows that the market filtering is in healthy development trend: from the angle of the filter material production, from America 2007 filtering market sales reached $31 billion, over a period of five years as a benchmark, the annual growth rate of 2.4%, Inda is expected in 2012 sales will increase to $35 billion. The fastest growing industry in the filter market is the industrial cleaning dust bag filter (HVAC), air filter, air filter, high efficiency filter (HEPA/ULPA), disposable face mask and automotive air conditioning filter. Including cellulose filter media, industrial filter material consumption in 2007 was 108.735 tons, the output value of $643000000, to 2012 increased by 14%, to $754000000. Which transportation, heating, ventilation and air conditioning (HVAC) accounted for 80% of the market share of the filter, 2007 consumption of 108.735 tons. In addition, air conditioning filter market will grow rapidly, even though the market is now less than 1% years of growth, but in high efficiency and high profit driven, its growth rate will reach 8% by 2012.

American Hollingsworth & Vose (H&V) has been an advocate of advanced technology, the product has been applied to the engine and a variety of industrial filtration, efficient and special filtration, clean room, water, liquid filtration and various air purification, vacuum cleaner and biological engineering filtration. Mayman Angelica, director of business development department, said the market for the highest requirements of the filter is small, long working life, low energy consumption and good performance, to develop a Capaceon technology for the H&V, for heavy air filter, folding air filter and lubricating oil and fuel filter. Capaceon technology can significantly increase the service life of the filter, improve the filtering efficiency, or reduce the size of the filter. In Capaceon. Last year H&V and launched a NANOWEB and Nanowave new technology, NANOWEB for gas turbine engine and heavy air filtration market. It has two kinds of extension product, one is that with synthetic fiber non hygroscopic filter, and the second is flame retardant type filter. At the same time, the company also plans to launch Nanowave extension of the varieties, by increasing the area of the filter medium to improve the mechanical performance of the filter.

Another company is committed to the development of new technology is the United States Ahlstrom company, its products are mainly used in the field of transportation. Mr. Jerome Barrillon, deputy manager of the sales department liquid filtration company said, "the market for fuel and water separation and filtration products require large amount of research, therefore, we are committed to the new water and fuel separation technology. In addition, the development of new materials has also been carried out, one of which is a new Disruptor technology, the traditional filter is very small in the filtration of viruses and bacteria such as particles, can make great pressure by water or liquid, so the flow rate is very slow, whereas the Disruptor uses a unique composite technology, containing aluminum ions onto the micro nano fiber glass fiber, made by wet method, the nano fibers create numerous holes in the web in those tiny particles, interception, and the impact on the flow resistance is small, not."

As with PGI, Ahlstrom also increase investment in new technologies. The company's industrial filter market is concentrated in North America, the main purpose of the liquid filtration, including milk, water and automotive industry, liquid filtration and separation. The company intends to use the existing Lineair brand to enter the air filtration market in 2010, such as spray paint shop, hospital and industrial gas turbine, etc..

Felt Southern is a manufacturer of 22 years experience in the production of filter materials, products are mainly used in industrial air filtration, such as a large number of flue gas and coal enterprises, power plants, cement plants, steel mills and asphalt plants, according to the company's sales department deputy director Lox Konesky - a folding filter material, its advantage is to produce low pressure drop and high penetration rate, especially suitable for high temperature pollution serious occasions.

Johns Manville is a has 25 years experience in the production of the company and master the advanced filter material production technology, mainly for air and liquid filtration market, such as ventilation and air conditioning (HVAC), automobile industry and efficient means of HEPA / ULPA, vacuum cleaners, toxic gas filtration, cooling oil, food and beverage, water treatment and swimming pool filtration, recent company also pharmaceuticals, machinery manufacturing, health care, chemical plant and a variety of industrial filter field made substantive breakthrough, the company filter separation manager Christian Hassmann Mr. said "through the use of nano fiber, and after wet, dry, spunbond and melting
