4223 Abstract FILTRATION FABRIC PRODUCED BY WET LAID PROCESS A nonwoven filtration fabric is composed of a plurality of fiber components of dissimilar denier and length which are evenly intermingled and bonded together in a sheet, including a first fiber component of staple polyester fibers of high denier and a textile length, a second fiber component of staple polyester fibers of low denier and shorter length than the first fiber component, a third fiber component of wood pulp fibers of shorter length than the first fiber component, and a suitable binder. The fabric is formed by a wet laid process in which the dissimilar fiber components are evenly mixed and distributed in a homogeneous slurry. A filter media made of the fabric has a high tensile strength, even pore size and distribution, low pressure drop, and is suitable for macrofiltration applications, such as filtering milk.
