Provided is a strong, flexible wet laid non-woven fibrous element comprised of polymeric fibrids as a binder. The polymeric fibrids have a softening point below the softening point of the fibers in the non-woven element, and are preferably cellulose acetate fibrids. Such non-woven elements can exhibit excellent wet web strength and dry strength, and are particularly applicable as filter elements. In a preferred embodiment, the non-woven element is comprised of glass fibers (1), synthetic short fibers (2) and the polymer fibrids (3). Such non-woven element exhibits excellent chemical resistance and a usefulness as a filter element in removing particulates from gases at lower temperatures. |
