DuraFiber, an adhesive melt blowing technology, features a single step process of melt extrusion, fiberization, and laydown on a moving substrate of hot melt adhesive. Unlike spiral, slot, or bead technologies, the DuraFiber process produces a layer of thousands of discontinuous fibers, where each fiber acts as an indenpendent bonding point between substrates. The system allows the user to control the diameter and density of the fibers, thereby creating a multitude of peel strength and coverage combinations. DuraFiber backsheet lamination reduces or eliminates film distortion and bleed through. Invisible ply bonding combines one or more layers of tissue/towel paper using a fine layer of fiberized adhesive in a single stripe or multiple stripes per converted product laydown. Procter ＆ Gamble patented the combining of multi-ply paper laminates in the early 1990s.
