Abstract

PURPOSE:To obtain a monwoven fabric with good dust collecting efficiency by using a low cost and stably supplied fiber through a mechanism wherein a synthetic fiber and a rayon fiber are combined as a fibrous substrate for a dustproof filter and treated by needling bcfore treated under heat and pressure. CONSTITUTION:As a fibrous substrates of a dustproof filter such as a dustproof mask and the like, 50-95wt% of polyolefin fiber selected from palypropylene fiber or composite fiber comprising polypropylene and polyethylene with 1-3 denier and 50-5wt% of celllosic fiber such as rayon and the like with 1-3 denier are blended and treated by needling to form a sheet like material of which fibers are intermingled, thereafter are passed between the nip of heating rolls to fuse polyolefine fiber. By this method, a substrate with low air passing resistance and high dust collecting efficiency is obtained by using a low cost and stably supplied fiber.
