Extendable nonwoven fabric and method for producing the same

摘要

An extendable nonwoven fabric which comprises a web of long filaments of mainly 3 mu m to 15 mu m 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.
