PROBLEM TO BE SOLVED: To provide a method for producing a stretchable nonwoven fabric for disposable paper diapers in which functionality and sensuousness required for disposable paper diaper can be improved and a method for producing the disposable paper diaper excellent in functionality, sensuousness and a fitting property, etc., obtained when worn. SOLUTION: The method for producing the stretchable nonwoven fabric for paper diapers comprises arranging an elastic yarn beam-winding body for winding several elastic yarns onto a bobbin in a beam state in which several elastic yarns are parallel arranged at an elastic yarn-feeding position in production process of the stretchable nonwoven fabric for paper diaper, positively rotating the elastic yarn beam-winding body, feeding elastic yarn while reeling the elastic yarn beam and inserting many numbers of elastic yarns fed into spaces between nonwoven fabric and fixing these yarns. The elastic beam winding body for production of stretchable nonwoven fabric for disposable paper diapers is obtained by winding many numbers of elastic yarns on the bobbin in the beam state in which many numbers of elastic yarns are parallel arranged. In the elastic yarn beam winding body, the yarn length (Lm) of wound elastic yarn, yarn number (E) and fineness (Ddtex) satisfy the formula: 1<L/(E×D)<7. COPYRIGHT: (C)2006,JPO&NCIPI
