Filtration is one of the fastest growing segments for nonwovens. Air filters control air purity in a wide range of industrial and domestic processes, from computing and telecommunications, to personal protection and medical care. Stricter environmental legislation, combined with raised health awareness, ensures the continuous demand for clean air. At the same time the need to reduce energy consumption for lower cost is ever present.

Our Daltex® filtration nonwovens have been designed and engineered in partnership with our customers to create solutions to some of the most demanding applications. Incorporation of additives and the flexibility to laminate to other materials, particularly meltblown, make these materials ideally suited to the increasing demands of the filtration market.

Daltex® nonwoven spunbond materials are highly air permeable, maximising air flow while minimising air flow resistance. Manufactured from polypropylene, our nonwovens have excellent chemical resistance and the inclusion of flame retardant and anti-microbial additives can provide added functionality in specific applications.

The diverse nature of our fabrics ensures they can be used in many air filtration devices helping to remove a wide range of contaminants from the air including dust, pollen, mould and bacteria. The industry standard, EN779:2012, defines filter efficiency dust holding capability and effect on pressure drop. The material characteristics, including fibre diameter, porosity, air permeability and thickness, classify our nonwoven polyproylene spunbond Daltex® Lowbond™ and Lowbond™ Ultra as G4 and M5 respectively.
