Filtration

Nonwovens Filtration
One of the fastest-growing segments within the industry, filtration offers a wide variety of applications for nonwovens in the filtering of air, bacteria, dust, gases and liquids.

Providing cost-efficiency and performance benefits to customers, nonwovens have become the media of choice for filtration applications, particularly where strength in high temperatures is advantageous.

Key uses for nonwovens include air filtration, fuel and oil filters in cars, food and beverage production, medical uses such as blood or water filtration, and general industrial purposes.

As experts in surface and web inspection for continuous production processes, AMETEK Surface Vision has the applications knowledge required to provide high-quality solutions for the nonwovens industry. Our monitoring solutions are trusted by major roll goods producers worldwide.

    • Nonwovens  Carded
      Carded

      Carding is a mechanical dry-laying process where fibers are combed into a web by a carding machine, a rotating drum covered with fine wires or teeth, providing good tensile strength.

    • Nonwovens Co-Form
      Co-Form

      This process combines short wood-pulp fibers with fine meltblown fibers to create a homogenous, pillow-like sheet – the fiber ratio determines material properties. It is ideal for personal care and medical uses.

    • Nonwovens Lamination
      Lamination

      Nonwoven materials can be laminated to enhance their properties and performance. This process can affect surface integrity, and so requires automated monitoring to reduce waste product.

    • Nonwovens Meltblown
      Meltblown

      Polymers with a low viscosity are extruded into a high-speed airstream upon leaving the spinneret. This results in scattering of the melt, which solidifies and then breaks up into a fibrous web.

    • Nonwovens Needlepunch
      Needlepunch

      Suitable for most fiber types, this process uses needles that are pushed and pulled through the web to entangle the fibers. This allows webs of various properties to be needled together.

    • Nonwovens Slitting
      Slitting

      A slitting machine, or slitter, is used to cut large rolls of nonwoven material into smaller rolls. This may affect the condition of the web, and so requires accurate monitoring.

    • Nonwovens Spunbond and SMS
      Spunbond and SMS

      By melting polymer granules and extruding through spinnerets, continuous filaments can be produced which deposit onto a conveyor, forming a uniform web. This provides a less flexible material with greater strength.

    • Nonwovens Spunlace / Hydroentangled
      Spunlace / Hydroentangled

      Hydroentanglement, also called spunlacing, uses fine, high-pressure water jets to make the fibers become physically entangled in a mechanical bonding process. It is sometimes combined with carding or wetform processes.

    • Nonwovens Wetform
      Wetform

      A mixture of water and fibers is deposited onto a moving wire screen, then drained to form a web. Further drying, rolling and treating follows to create a wide range of materials.

    • Nonwovens  Airlaid
      Airlaid

      This is a versatile dry-laying process where short fibers are fed into an air stream, then sent to a moving belt or perforated drum, where they form a web.
