Airlaid Specification

Properties

Compared with normal wet-laid paper and tissue, Airlaid Paper paper is very bulky, porous and soft. It has good water absorption properties and is much stronger compared with normal tissue.

Nonwoven Fabric is a fabric-like material made from long fibers, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as woven nor knitted. Nonwoven materials typically lack strength unless densified or reinforced by a backing. In recent years, nonwovens have become an alternative to polyurethane foam.

 

Main characteristics are:
  • Soft, does not scratch.
  • Non-linting, no dust, no static.
  • Strong, even when wet, can be rinsed and reused.
  • Clean, hygenic, can be sterilized.
  • Textile- like surface and drape.
  • Can be dyed, printed, embossed, coated and made solvent resistant.

 

 

 

 

 

 

 

Unlike the normal papermaking process, air-laid paper does not use water as the carrying medium for the fibre. Fibres are carried and formed to the structure of paper by air.

The raw material is long fibered softwood fluff pulp in roll form. The pulp are defibized in a hammermill. Defibration is the process of freeing the fibres from each other before entering the papermachine. Important parameters for dry defibration are shredding energy and knot content. Normally an air-laid paper consists of about 85 % fibre. A binder must be applied as a spray or foam. Alternatively, additional fibres or powders can be added to the pulp which can then be activated and cured by heat.
