Abstract

An improved intimate cardable fiber blend containing polytetrafluoroethylene fibers, dual glass fibers and polyphenylene sulfide fibers and a filtration felt including a needled batt of the intimate cardable fiber blend made by mechanically blending the polyphenylene sulfide fibers and glass fibers with polytetrafluoroethylene fibers, carding the blend to form a nonwoven batt and needling the batt to provide a felt.
