The first and the second outer layers including a plurality of short fibers, a triggerable binder, and at least one of the first or second outer layers including a plurality of long fibers. The middle layer including a plurality of short fibers, a triggerable binder, and optionally a plurality of long fibers. The dispersible nonwoven web having a weight percent of the long fibers in at least one of the first or the second outer layers that is greater than a weight percent of the long fibers in the middle layer.
