Nonwovens are driving the growth of nonwoven filter media

Nonwovens dominate To understand the growth of nonwovens(China Filter Material Factory) in filtration, one must understand the close relationship with membrane filtration(Non-Woven Filter Material Company) media. Microporous and reverse osmosis membranes arerapidly developing in many liquid applications. Most membrane applications aregrowing at a rate of 8% to 10% per year. Those who treat water and wastewatergrow by more than 15% each year. Lighter levels of filtering at many market segmentsrequire lighter weight, and some industry experts believe that this or higherlevel of growth will be sustainable for many years. The main beneficiaries offilm growth and market penetration are still non-woven fabrics used incombination with films of various configurations. For example, in the global $30 million nonwoven market, nonwoven wet polyester substrates support reverseosmosis membranes in spiral wound modules. These modules have been found insystems located mainly in arid areas where seawater is converted to drinkingwater. Almost all microporous membrane filters sold use spunbond fabrics aspleated supports and separators. Nonwovens have annual sales of approximately $35 million.
