Abstract
A novel filtration medium, preferably of the closed loop belt type, comprising a woven substrate which is overlaid by a disparate layer comprising a plurality of individual thermoplastic resin particulates which are controllably spaced apart from one another and bonded at fixed spaced apart locations to one to another and to the strands of the woven substrate. These resin particulates serve to define the pore structure and pore size for the medium. A method for the manufacture of the filtration medium is disclosed.
