FILTER CARTRIDGE CONSTRUCTION AND PROCESS FOR FILTERING PARTICLE-CONTAINING PAINT COMPOSITIONS

摘要

A filter element for filtering a particle-containing paint composition or a particle loading slurry composition which is a precursor to a particle-conta ining paint composition is provided. The filtration element comprises at least one filtration layer formed from woven polymer fibers and having substantially uniform pores and two spacer layers. The spacer layers have raised projectio ns to create a space between adjacent spacer layers having contacting projectio ns. The filtration element has a pleated or spirally wound configuration.
