METHOD FOR PRODUCING ELASTIC NONWOVEN FABRIC SHEET, AND ELASTIC NONWOVEN FABRIC SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an elastic nonwoven fabric sheet that has high elongation and also resists perforation.;SOLUTION: A method for producing an elastic nonwoven fabric sheet includes the steps of forming a napped fiber on the surface of a filament nonwoven fabric, passing the filament nonwoven fabric and an elastic resin material extruded in molten state through a nip roll, and fusing together the napped fiber of the filament nonwoven fabric and the elastic resin material, to form a composite sheet, and drawing the composite sheet.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
