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 web formed from inelastically stretchable continuous fibers that are formed with a melt extruder and subjected to hot air blast sideways relative to a nozzle of the melt extruder and suction from a suction box, said inelastically stretchable continuous fibers being substantially unfused to one another; orienting said inelastically stretchable continuous fibers in said inelastically stretchable fibrous web in a first direction while separating any fused ones of said inelastically stretchable continuous fibers; positioning said inelastically stretchable fibrous web 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 web to each other in said first direction and a second direction orthogonal to said first direction.
