Viledon cooltexx filter media with a cellulose content are used predominantly in Hydrophilic fine-fiber medium with good water wettability.

arrestance only a low pressure drop ensues. Since cellulose can be bonded only
chemically, not thermally, the mechanical strengths will usually be lower than with
polyester spunbonded nonwovens, so that their use is restricted to systems with
low tensile stresses.
