Polyester Needle Punched Nonwoven for Liquid Filter Raw Materials

1. Material & Filtration Principle Constructed with impregnated polyester or polypropylene fibres, the filter medium develops a sturdy, chemical-proof and highly porous fibre structure. When fluid flows through the material, its compact fibre framework captures suspended contaminants, sediments and tiny particles relying on physical blocking and deep-bed filtration effects.

2. Typical Applications It is extensively adopted as either preliminary filter media or core filtration layers for domestic water purification equipment, industrial liquid filter cartridges and filter bags.

3. Application Advantage Thanks to its reliable filtering performance, the nonwoven material extends the service cycle of finished filter products effectively.

4. Cost-Effective Performance Less frequent filter element replacement cuts overall operating costs, delivering an economical option to sustain stable water cleanliness.
