Abstract:
1. A process for making a composite sheet which comprises: providing an elastically stretchable layer having upper and lower surfaces; providing an inelastically stretchable fibrous layer formed with inelastically stretchable continuous fibers that are laid down upon a support so that the continuous fibers lay upon one another without being bonded together thereby forming the inelastically stretchable fibrous layer; orienting said inelastically stretchable continuous fibers in a first direction; positioning said inelastically stretchable fibrous layer on at least one of the upper and lower surfaces of the elastically stretchable layer; and intermittently bonding said elastically stretchable layer and said inelastically stretchable fibrous layer to each other in said first direction and a second direction orthogonal to said first direction, wherein the step of orienting said inelastically stretchable continuous fibers substantially in said first direction causes a tensile strength S
