    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.

    摘要： The present invention relates to a method of producing a transversely aligned web comprising the steps of extruding melted resin from a spinning nozzle to direct the metal resin downward, blowing off a primary airflow at a high temperature and at high velocity from an annular primary airflow nozzle, blowing off a pair of secondary airflows at a high temperature from a pair of secondary airflow nozzles, colliding with the pair of airflow blown off from the pair of secondary airflow nozzles each other below the spinning nozzle, spreading the colliding secondary airflow at least partly in the width direction of the conveyor, and piling on the conveyor the spun filaments so that transversely aligned web is formed of the filaments which are aligned in the width direction of the conveyor.
