Web bonding

Airlaid webs have little strength in their unbonded form. Therefore, it needs to be strengthened. This is affected by bonding, a vital step in the production of airlaid nonwovens. The choice of method is at least as important to ultimate functional properties as the type of fiber in the web.

There are three basic types of bonding:

  • Chemical
  • Thermal
  • Mechanical

 

Type of bonding processes based on final product

Final application: absorbent core material for baby diapers, feminine hygiene and incontinence products

HBAL – Hydrogen Laid process = Fluff pulp + calender bonding

TBAL – Thermal Bonding AirLaid process = Fluff pulp + bonding fibers

Final application: absorbent cores and different types of wipes

SBAL/BBAL – Spray or Binder Bonding Airlaid process = Fluff pulp + binder dispersion

MBAL – Combination of SBAL/BBAL bonding in combination with TBAL – Thermal Bonding

Airlaid process = Fluff pulp + bonding fibers + binder dispersion

HLAL – Hydro Laced Airlaid process = Combination of airlaid with spunlace technology

 

NEWS! Unique bonding process for biodegradable wipes

Final application: Disposable, flushable, dispersible and 100% biodegradable wipes

CAMPEN Machinery has perfected a 20-year-old technology to combine airlaid with the spunlacing process to produce a nonwoven for wet and dry wipes which is up to 100% disposable and biodegradable. This nonwoven is characterised by extremely soft wipes with a very high tensile elongation making this raw material a sustainable product without compromising on quality.

Furthermore, the process makes it possible to use different types of man-made or natural fibers in a homogeneous mixture or in a sandwich construction. This gives the customer the opportunity to design and produce a variety of unique final products with different product performance.
