    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 pair of stretching pulleys (3a,3a) are rotatably mounted on a pair of support plates (3,3) within a housing (1). A belt (3b) is wound around the upper part of the stretching pulley and a number of turn pulleys. A film (F) introduced onto the stretching pulley is held between the belt and the stretching pulley and is transferred. Air flow generated by a fan (51) and heated with a heater (5) is blown against the film through a louver and circulates through bellows mounted to the housing to return to the fan. The stretching pulley is partially cooled in a water bath (4c). The support plates are rotatably connected to screw shafts, thereby changing a distance and angle between the plates. The stretch width or stretch ratio of the film is thus adjusted with the change of the distance and angle.
