Abstract

Non-woven matl. is used as a filter material for liquids or gases as a replacement for conventional woven filter materials, or for filter materials incorporating supporting cloths, is cheaper due to the lack of weaving. Pore size distribution is such that freedom from preferential flow passages in the material is obtd. The filter material consists of a fibre mat of natural or synthetic material which is knitted mechanically in a manner previously used for silk in which fibre bundles are partially looped around adjacent bundles and partially cross-linked at random to other bundles. This mat is treated with a bonding agent such as resin applied by a heat treatment process opt. cured at high temp.
