    摘要： An extendable nonwoven fabric which comprises a web of long filaments of mainly 3 µm to 15 µm in diameter that is prepared by stretching at least in one direction at a stretching ratio of 3 or more, and which fabric is 150% or more in elongation when it is elongated at right angles to the direction of stretching, a composite extendable nonwoven fabric which is made by laminating an elastomeric material with the extendable nonwoven fabric, and a method for producing the extendable nonwoven fabric, in which the extendable nonwoven fabric is low in basis weight, large in the degree of elongation, and excellent in strength and touch feeling and suitably used as the elastic material for sanitary fittings.

    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 µm to 15 µm 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.
