Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an absorptive article with a nonwoven fabric which exhibits high pliability, entire planar uniformity, satisfactory surface smoothness and soft and comfortable touch.

SOLUTION: At least two layers of a spun bonded fabric layer formed of a web by a spun bonding process and a melt-blown process, both based on a raw material extruded with a flexibilizer added in a raw material stage prior to melting/extrusion, are laminated over each other to obtain a nonwoven fabric laminate. This laminate is used as an absorptive article by positioning the spun bonded fabric layer at the outer face of the absorptive article.
