摘要： A longitudinally stretched nonwoven fabric and a method for producing the same, which nonwoven fabric is a web mainly composed of long fiber filaments of 3 .mu.m to 15 .mu.m in diameter and made by short distance stretching in one direction at a stretching ratio of at least 5, and which production method is characterized in the steps of: maintaining the spun filaments in a draftable state; cooling the filaments with a cooling fluid, then guiding the filaments onto a conveyer with inclining the flow of filaments toward the transferring direction, and sucking by a reduced pressure from the back side of said conveyer, and further subjecting the web of filaments to short distance stretching in the longitudinal direction.
