Oerlikon Neumag is the leading world-wide supplier of M&J Airlaid Technology. The core of the Airlaid Technology is the patented Fibre Forming System that enables the production of wide width webs based either on 100% pulp fibres or homogeneous mixtures of different fibres and powders. Typical raw materials are fluff pulp, Bicomponent bonding fibres and Super Absorbent Powder for absorbent core material.

Airlaid Technology

The M&J Airlaid Technology is extremely flexible with regard to which raw materials and fibre lengths can be used and combined in the same process. The Patented Forming technology enables the mixing of different short and long fibres and powders in the same forming head where the components are homogeneously mixed before formation. Due to the formation geometry this homogeneous mix is maintained during web formation, ensuring optimal use of all the components in the web. This means that webs can be engineered with specific end uses in mind. Whether it is single or multilayer products each layer can be designed to meet the needs at that particular place in the web, for instance acquisition, spreading and absorption layers. The ability to mix powders homogeneously into the web also means that bonding powders can be used in the process. A most important feature of the Airlaid Technology is the ability to produce products free of undefibrated material and lumps of rolled up fibres. These are removed from the forming head and recycled to the defibrators before the web is formed.

The Airlaid Principle

The Airlaid principle is to lay the fibres or fibre / powder mixture onto a horizontal moving forming fabric / wire through a horizontal forming outlet system. The forming head acts as a buffer tank, evening out any variations in the fluff pulp sheet, or the raw material supply in general. It distributes the fibres across and along the machine direction, ensuring excellent CD/MD profiles, before they via a horizontal forming screen are deposited on the forming wire, under which a vacuum is constantly maintained for even web formation.

Advantages of the Airlaid Technology

Airlaid Products

By applying the previously mentioned bonding methods, either alone or in combination with each other, products can be produced that cover a wide range of everyday products such as sanitary napkins, tabletop products, dry and wet wipes, health care and a number of other applications.

Bonding methods:

• Thermal Bonding


• Latex Bonding


• Multi Bonding


• Spunlacing (Hydroentanglement)


• Other bonding methods such as hydrogen or X bonding, calender bonding etc
