发明名称 NONWOVEN FILTER MATERIAL
摘要 A nonwoven filter material for use in the filtration of fluid. The filter material comprises an inner layer of a plurality of continuous filaments in surface to surface contact with at least one outer layer of a blended fibrous web. The inner layer of continuous filaments and the outer layer of fibrous web are bonded together by an aqueous binder. A filter thusly constructed permits the inner layer of continuous filaments to act as a surface filtration and the outer layer of fibrous web to act as an in-depth filtration of fluid contaminants.
