Hygiene

Nonwovens Hygiene
Low production costs and the capability to be manufactured with qualities such as softness and resistance to infection make nonwoven fabrics an important material for disposable hygiene products.

Nonwoven materials provide breathable, absorbent hygiene products for both adults and children. Defect detection is important to ensure product integrity and deliver the expected performance quality.

The main uses for nonwovens in this segment are for diapers, adult incontinence pads and feminine hygiene products. Other disposable hygiene products, such as chemical-treated moist wipes also rely on nonwoven materials.

AMETEK Surface Vision supplies nonwovens manufacturers globally with the inspection solutions they need to ensure high quality products. Our systems have been trusted by major roll goods makers for decades, providing accurate online detection, classification and visualization of surface defects and web imperfections.

    • 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.
