Nonwovens are used for water and air filtration application as well.

The NW materials have high heat resistance, ease of strikethrough. They can serve efficiently at long service life. They also have a positive impact on reducing energy costs.

Conventional filter media such as paper, cloths, glass or carbons were replaced with this new generation NW materials which are combining several different types of nonwovens.

Due to their uniform structure, high tensile strength and tear resistance, retention capability, chemical and abrasion resistance, air permeability the nonwovens used in filter media bring advantages.

Mainly, spunbond, airlay, spunlaid, meltblown, needlpunch, thermobond Technologies are used for the production of NW filter media. In some rare applications, Hydroentanglement and Wetlaid are also used.
