摘要:
This invention aims to provide a composite sheet having a layer of inelastically stretchable continuous fibers improved so that a possible unevenness in fiber diameter may be minimized. A composite sheet 10 comprises an elastically stretchable layer 3 and an inelastically stretchable layer 2 formed with inelastically stretchable continuous fibers 6 bonded to at least one surface of the elastically stretchable layer 2 intermittently in one direction. The continuous fibers 6 are oriented substantially in one direction thereof so that the composite sheet 10 may present a ratio S 1 /S 2 of 3.0 or higher where S 3 represents a tensile strength in this one direction and S 2 represents a tensile strength in the direction orthogonal to this one direction.
摘要:
A composite web 10 including an elastically stretchable web and an inelastically stretchable web bonded together is stretched on a course defined between at least two nip roll pairs 31, 32 to obtain an elastically stretchable composite sheet 20. The composite web 10 is brought into contact with a peripheral surface of at least one roll of each nip roll pair 31, 32 over an area of the peripheral surface defined by a quadrant of this roll's circular cross section.
