Air filtration plays an important role in improving air quality and hygiene. The demands for air quality and hygiene at work places have increased greatly due to new regulations and a change in health consciousness.

Chemical bonding process with the light weight foam will result in the binder bonding of the fabric surface. Very little energy is required for evaporation of the water contained in the binder. Nonwoven fabrics for filtration application were produced from polypropylene (PP) and polyester (PET) fibres using the hydroentanglement and chemical bonding techniques. Three different pressures of AquaJet, 60, 120 and 200 bar were selected as variable parameters for the trial. The chemical binder applied by the weight of material was 25% and 40%, with 30% of solid in the resin. The physical, mechanical and performance properties were measured and compared.
