Definitions for "Filter paper"
Porous paper used for filtering liquids.
A permeable web of randomly orientated fibres, generally cellulose (I.e. wood pulp, cotton) or glass fibre is formed from water draining from a carefully prepared suspension of these fibbers fed to a continuously travelling, endless belt of wire mesh - a paper making machine. The preparation and type of fibre controls the permeability within any one thickness and weight per unit area of grade. Various grades are available with these variations and also with resin addition to give strength to the paper when wet. A further variation arises with a crepe finish whereby the effective area of paper for a given weight is considerably increased. A wide range of filter papers is available commercially for the removal of particles from liquids and gases.
