PROBLEM TO BE SOLVED: To provide a method for producing a stretchable nonwoven fabric for paper diapers, which can improve functionality and aesthetics required for paper diaper products. That is, the present invention provides a method for producing a disposable diaper that is excellent in functionality, aesthetics, and fit when worn. An elastic yarn beam winding body in which several elastic yarns are wound in parallel in a beam state and arranged on a bobbin is arranged at an elastic yarn feeding position in a manufacturing process of a stretchable nonwoven fabric for paper diapers, and an elastic yarn beam A stretchable nonwoven fabric for paper diapers is manufactured by positively rotating the winding body to feed the yarn while unwinding the elastic yarn beam, and inserting and fixing a large number of fed elastic yarns between the nonwoven fabrics. Also, an elastic yarn beam winding body in which a large number of elastic yarns are rolled up on a bobbin in a beam state, and the length (Lm), the number of yarns (E), and the fineness (Ddtex) of the wound elastic yarns Is an elastic yarn beam roll-up body for manufacturing disposable diaper stretchable nonwoven fabric, which satisfies the following formula. 1 <L / (E × D) <7 [Selection figure] None |
